THE SAMSUNG GALAXY S4—a svelte, elegant phone—is an enticing gadget, and the first time you hold it in your hands, you’ll immediately want to put it through its paces: calling friends, browsing the Web, checking your email, and more. As you’ll see in the rest of this book, it can do some remarkable things that make you feel as if the phone has superpowers.

To help you unlock all those powers, though, you need a solid understanding of how the Galaxy S4 works and familiarity with all its different parts. You’ll want to know where all its buttons, keys, and ports are located, for example—not to mention how to get to your Home screen and panes, and use some of the device’s amazing new features, like its ability to let you navigate by merely moving your eyes.

THREE-QUARTERS OF THE WAY up on the right side of the Galaxy S4, you’ll find a small, rectangular silver button. It may be only a single button, but it’s a hardworking one, and it performs multiple functions. Press it with your S4 turned off, and your S4 springs to life. Press and release it when your S4 is turned on and active, and it puts the phone into Standby mode. If your S4 is turned on, press and hold it and a screen appears that lets you do the following:

When you put the Galaxy S4 on Standby using the Power/Lock button, the screen stops responding to touch. It blacks out, indicating that the screen is locked. Always lock the screen before putting the Galaxy S4 in your pocket or bag to avoid accidental screen taps and potentially embarrassing unintended phone calls. In fact, every time you leave the phone untouched for a certain amount of time—as little as 15 seconds to as much as 10 minutes (Brightness)—the screen automatically locks itself.

While the screen is locked, the Galaxy S4 still operates behind the scenes, checking email and Facebook on schedule. You can still get phone calls and text messages, and even listen to music while the screen is locked.

When you again want to use the Galaxy S4, you’ll need to unlock it. Press the Power button or the Home key. Then put your fingertip on the screen and slide it to the right or left. Your Galaxy S4 is now ready to do your bidding. You’ll get notifications about missed calls, text messages, and so on. If you’ve set up a PIN on your phone so that only someone with a password can use it, you’ll have to type in the PIN before you can use your phone. (See Screen lock for details on how to set up a PIN.)

You can adjust the amount of time it takes for the Galaxy S4 to lock itself. You can also turn off Locked mode entirely. And for added security, you can also require that a password be used to unlock your S4, or even that a specific finger swiping motion be performed on the keyboard before it can be unlocked. For details, see Screen lock.

AT THE TOP OF the Galaxy S4, you’ll find a 3.5-millimeter headset jack. Notice that it’s a head set jack, not just a garden-variety head phone jack. It doesn’t just let you listen; it accepts incoming sound as well. That’s so you can plug a headset (like an earbud headset) into it and use it for making phone calls.

THE SCREEN IS WHERE you and the Galaxy S4 do most of your communicating with each other. Compare the Galaxy S4’s screen to that of almost any other phone, and you’ll immediately notice how roomy it is—5 inches, measured diagonally (technically, that’s 1920 x 1080 pixels). It’s got extremely high resolution (443 pixels per inch, for the techie crowd). When you turn it sideways, it switches to a widescreen TV and movie format.

Proximity sensor. Have you ever noticed that when you’re talking on your S4, the screen often goes blank? That’s thanks to the proximity sensor. It senses when your face is close to it during a phone call and automatically turns off and blanks the touch screen as you keep talking. It does this to save power, and so you don’t accidentally touch the screen while talking and perform some unwanted task.

Accelerometer. As its name implies, this sensor measures acceleration and motion. The Galaxy S4 uses the accelerometer to sense the orientation of the screen and turn it to either landscape or portrait mode. But clever app makers use it for other things as well, such as automatic collision notification, which detects when you’re in an accident and then automatically makes a call for assistance for you. There’s even an app that works with the phone’s magnetometer to detect potholes as you drive, and create a log about their locations, which you can then email to your local department of public works. (It’s called Pothole Agent. Search for it on Google Play, as described on Using Google Play Store.)

Gyroscope. This measures motion and is used for a host of features. For example, the S4 uses the gyroscope in concert with the accelerometer to interpret motion gestures you make and let you operate the phone by waving your hands.

Infrared gesture. This sensor uses infrared light to sense your gestures so that you can control the S4 without touching it. Yes, you read that right. You can control it by waving and other gestures thanks to this sensor. And as you’ll see later in this chapter, you can even control scrolling by moving your eyes. (You’ll learn all about these tricks later in this chapter on Pinch and Spread.)

THE GALAXY S4 MAKES sure to keep you updated with information about its current status and any news, updates, and information it thinks is important. It does so by displaying a variety of icons in the status bar at the top of the screen. The status bar is divided into two parts. On the right side, you’ll find icons that inform you about the current state of the Galaxy S4, such as signal strength, 3G or 4G connection status, the time of day, and so on. At left is the Notification area, which alerts you when you have email or voice messages waiting, an event on your calendar is about to occur, and more.

When you see a notification on the left side of the status bar, drag down the Notification panel to see more details. You can also act upon the notification by tapping its icon after you drag it down—like checking your email or running an app that you’ve just downloaded. There’s also a Clear button that makes all notifications go away.

Most of the time you use your Galaxy S4, you’ll be tapping on virtual buttons on the keyboard. But down at the bottom of the Galaxy S4, there are three keys, one fat, black physical one and two virtual ones that light up only when you touch them. From left to right, here’s what they do.

Repeat after me, Dorothy: There’s no place like home, there’s no place like home.…Wherever you are on the Galaxy S4, press the Home key and you’ll come back to the familiar Home screen. You won’t even need to tap your ruby slippers together.

Now, take a look back to the screen you get to when you hold down the Home key. Tap the Google icon at center bottom and you enter the world of Google Cards—a series of compact panels that give you any information important to you. Google Cards can keep you apprised of the weather, any trips you have coming up, what the traffic is like on the way to work, and more. See Using Cards in Google Now for details.

FOR TRANSFERRING FILES AND syncing music and movies between your computer and the Galaxy S4, there’s a micro USB port at the bottom of the phone. A micro USB port is much smaller than the normal one on devices like printers. To connect the S4 to your computer, you’ll need a micro USB cable, one of which comes in the Galaxy S4 box. The S4 can connect to both Macs and PCs. When you connect your S4 to a computer by USB cable, your phone gets power and charge from the computer. But it charges at a much slower rate than when you use the normal charger.

The Micro USB port is also a charger port. Connect the charger attachment to one end of the USB cable and the other end to your phone to start the charging process. If you use power-hungry features like video and GPS, you may have to charge the S4 every night. If you stick to mostly phone calls and text messages, you may be able to get by with charging only two or three times a week.

You can use the Galaxy S4 while it’s charging, unless the battery has run down completely. In that case, it’ll need to build up a charge before you can turn it on.

This port does one more thing as well. The S4 may be small enough to fit in the palm of your hand, but it’s still a big-time entertainment machine. That’s because it’s HDMI (High-Definition Multimedia Interface) capable. With it, you can view videos and photos taken on your Galaxy S4 right on your computer or TV screen—as long as they also have HDMI ports. Plug one end of the cable into your Galaxy S4, the other into your PC or TV, and you’re ready to go. What does that have to do with the USB port? Plenty: You can buy a special attachment to connect your phone to an HDMI device. See Connecting to the TV by Cable for details.

When you connect your Galaxy S4 to a PC for the first time, your PC may not recognize it. That’s because your PC may need special drivers (small pieces of software) to communicate with the Galaxy S4. Windows will try its mightiest to find the drivers, but there’s a chance it won’t be able to locate them. If it doesn’t, you can go over to the Samsung help website (www.samsung.com/us/support/) and search for Samsung Galaxy S4 drivers. Then download the drivers and follow the instructions for installing them.

IS YOUR RINGER TOO loud? Too soft? Get it just right by using this long silver key on the S4’s upper left. Press the top part to make the volume louder, and the bottom one to make it softer. When you press, a ringer volume app pops up on your screen, showing you how much louder or softer you’re making the ring.

THE GALAXY S4 HAS a battery cover. Yes, that’s right, an actual battery cover—you can remove the battery and replace it with a new one, unlike some other cellphones. To remove the battery, flip the S4 over, put your finger underneath the small plastic slot on the upper left and pull off the battery cover. You’ll see the battery, which you can easily remove by putting your finger into the slot at the bottom and gently pulling up. Don’t pull it hard or yank it.

The Galaxy S4, despite its large screen and considerable capabilities, can go a reasonably long time on one battery charge. But if you use a lot of power-sucking features, you may not even be able to get through one whole day without having to recharge. In addition to turning off the screen or putting it into Standby mode when you’re not using it, there’s a lot you can do to make your battery last:

Be smart about email fetching. The more often the Galaxy S4 checks email, the faster the battery runs down. Either check email manually only when you need to, or increase the interval at which the phone checks. Launch the Email app, press the Menu key, and then select Settings and tap the name of your email account. Tap “Sync schedule”→“Set sync schedule.” You can choose from intervals between 15 minutes and 12 hours, or manually.

Use “Power saving mode.” Power saving mode turns your Galaxy S4 into a power-sipper. To do it, from the Home screen, tap the Settings button, select Settings→“My device” and then turn on “Power saving mode.”

Turn off antennas you’re not using. If you’re not using a Bluetooth headset, and don’t need WiFi or GPS services at the moment, by all means turn them off. They use up tons of power. Pull down the Notification panel, and you’ll find widgets for turning off (and back on) WiFi, GPS, and Bluetooth. Putting the Galaxy S4 into Airplane mode turns off all these settings at once, as well as turning off the radio that connects you to the cellular network. Find the Airplane mode widget by sliding the widgets to the left.

JUST ABOVE THE BATTERY, you’ll also find a small slot for the MicroSD card, which is about the size of a fingernail—and much smaller than the normal SD memory cards used in cameras. Your Galaxy S4 may not have come with an SD card, so you may have to buy one. The S4 can use one that stores up to 64 GB of data. Place the card in the slot with the arrow facing in. You’ll hear a click when it’s in place. After that, replace the battery cover.

After you install the card, and you turn on the phone, you’ll see a notification that the S4 is preparing the microSD card for your use. Then, go to the Home screen and press the Menu key. Select Settings→Storage. Scroll down, and you’ll find a new group of settings under “SD card,” listing information like how much total space is on the SD card and how much space remains. (If that information doesn’t appear, it means that your SD card hasn’t been formatted properly. There’s a simple solution: tap, “Mount SD card.” If your phone doesn’t recognize it after that, tap “Format SD card.” That should do the trick.)

When you’ve done that, turn off the phone’s power and remove the battery cover. You can then slide out the MicroSD card. Then insert a new MicroSD card and follow the instructions in this section for telling your Galaxy S4 to recognize it.

YOUR SAMSUNG GALAXY S4 includes not one, but two cameras, both capable of taking videos as well as photos. The camera on the back, which is the one you’ll normally use for taking photos and videos, has a whopping 13-megapixel resolution. The camera that faces you is primarily designed for video calling and video chat, although you can also take photos with it (self-portraits mostly). It’s got a 2-megapixel resolution. Don’t look for a physical camera button for taking photos; instead, you tap an onscreen button (Taking Still Photos).

TO ENJOY ALL THE services your Galaxy S4 is capable of delivering, you need to have a Google account, and possibly a Samsung account as well. On your smartphone, an account is a central location for managing all the services you can get. The Google one is absolutely necessary, but you may want to set up a Samsung one as well. This section tells you what you need to know about each.

In order to use your S4, you need a Google account. That’s because the S4’s underlying software is made by Google, and uses many Google services, such as Maps, Gmail, and more. If you already have a Google account—if you’ve ever used Gmail, for example—great! You can use that account and all the information and settings you’ve stored in it. Or, you can create a new Google account when you sign in to your S4 for the first time and start fresh.

Dock. Just below the app icons is a row of five icons. They sit in an area called the Dock, and they’re different from the app icons. Unlike the app icons, you can’t delete them. As you’ll see in a little bit, there are other screens you can move to, called panes or panels, but the icons in the Dock stay in place no matter which pane you visit. (The app icons change according to what pane you’re on.) The Phone icon launches the Phone app; the Contacts icon shows you your contacts; the Messaging icon lets you send and receive text messages (it shows how many messages you’ve got waiting); the Internet icon launches your web browser; and the Apps icon reveals a whole new screen called the App Drawer, filled with apps, apps, and more apps.

Press the Launcher icon, and up pops the App Drawer, which includes all the Galaxy S4’s preinstalled applications, plus any apps that you’ve downloaded and installed. There’s more than can fit on one screen, so swipe your finger to the right to get to another screen filled with them. Tap any icon to run the app.

Look up at the top of the App Drawer. There are three tabs: Apps, Widgets, and Downloads (represented by a down-arrow icon). The Apps tab, naturally, shows all your apps. Tap Widgets, and you’ll see all the widgets on your S4—these are handy little gadgets that accomplish tasks for you, like displaying weather or traffic information.

Tap the Download icon, and you’ll see just the apps that you’ve downloaded to your S4. Those apps also show up in the Apps tab, which lists every app on your S4, whether built in or downloaded.

The Galaxy S4 is powered by an operating system from Google called Android, as are many other phones, such as the HTC EVO 4G and HTC One. The Android operating system is constantly getting updated, and those updates are automatically sent to your phone when they’re available. So what you see on your S4 may vary slightly from what you see onscreen here, depending on the version of Android you have on your phone. At this writing, the Galaxy S4 comes with Android version 4.3, nicknamed Jelly Bean.

Also, it’s common for the manufacturer to tweak the phone’s interface, sometimes in significant ways. Samsung adds its own TouchWiz interface, which makes many changes to Android. So when you compare the Galaxy S4 to other Android phones, you’ll notice differences.

There’s still another reason why your Galaxy S4 may differ slightly from what you see in this book. This book happens to be written based on the Samsung Galaxy S4 sold for T-Mobile phones, so it may slightly differ from what you see on phones from other carriers.

HERE’S ONE OF THE many nice things about the Galaxy S4—it’s easy to put your personal mark on it. Wish there were different apps on the Home screen? No problem; you can easily add them. Want to change the location of apps, or move around widgets and add new ones to each of your panes and the Home screen? It’s a breeze. The rest of this section shows you how.

The Home screen and panes have limited real estate—there’s only so much you can put on them. In fact, when the phone is factory fresh, the Home screen and panes may already be full. If you try to put something new on them, like an app or a widget, the S4 won’t let you do it. Nothing happens when you hold your finger on the screen or pane. In that case, you have two options: delete apps or widgets (Folders) or create a new pane (Deleting and Adding Panes).

If you select a picture from the Gallery, you can crop the photo to fit the screen. The S4 suggests a crop for you. You can change it by moving any of the squares that define the crop. Make your selection, tap Done, and you’ll see only the cropped area fill your screen.

This option lets you add apps or widgets to your Home screen or any pane. A widget is an applet that performs a small, specific task, often grabbing and displaying information from the Galaxy S4 or the Internet. When you select this option, you get sent to the App Drawer, with the Home screen or a pane in the background. You’ll see the familiar tabs along the top—Apps, Widgets, and the download icon. Tap either Apps or Widgets, depending on which you want to add. Swipe to see more apps or widgets if there are more than can fit on one screen. If you want to add an app, hold your finger on it. Then drag it up into the brighter portion of the screen above it and let it go.

When you add an app to your Home screen or a pane, you’re not actually moving that app to the screen or pane. Instead, you’re adding a shortcut to the app, and that’s a good thing. When you tap the shortcut, you run the app, just as if you had tapped it in the App Drawer. But there’s a difference: If you delete the shortcuts on the Home screen or pane, you don’t delete the app itself. It still lives on. But, if you delete the app from the App Drawer, it disappears from your S4.

Folders hold information and files, the same way they do on computers. You’ve already got lots of folders on your Galaxy S4, like your folder full of contacts, and bookmarks from your browsers. When you install apps, they may create their own folders as well—the Pandora Internet radio app, for example, creates a folder of your radio stations. You type in a name before placing the folder.

WITH THE GALAXY S4, your fingers do the walking. They do all the work that you do on a computer with a mouse or keyboard. Here are the eight finger strokes you can use on the phone’s screen.

Tapping is as basic to the S4 as clicking is to a mouse. This simple gesture is how you press onscreen buttons, place the cursor for text entry, and choose from menus. Note that’s a finger tap; the screen is designed to detect a fleshy fingertip, not a stylus.

LOOK MOM, NO HANDS! No longer is that only the cry of a child showing off riding a bicycle without touching the handlebars. You can do the same thing with your S4. Amazingly enough, you can control it by just moving your hands without touching the screen, or more remarkably, simply moving your eyes.

These are probably the most mind-boggling new features added to the S4. All you need to do is move your eyes to control the screen. And it’s so easy, that you don’t really need to do anything except what comes naturally, because they follow the way you normally move your eyes when you read.

Smart Scroll. When this is turned on, the S4 uses its camera and software magic to let you scroll through screens and web pages by merely tilting your head. Tilt your head down to scroll down, and up to scroll up. You’ll know Smart Scroll is turned on when you see an eye icon in the status bar. If you prefer, you can instead tilt the S4 forward or back to scroll. But what fun is that?

Smart Stay. This fixes one of the most common annoyances with a smartphone. You’re doing something on the phone, but you haven’t touched the screen for a while, so the screen turns off. Smart Stay fixes that. As long as you’re looking at the phone, it stays on. (Smart Stay is the only feature that’s not brand-new with the S4. It’s been around since the S3, but it works better now.)

Smart Pause. Here’s another very cool feature. While you’re watching a video, if you look away from the screen, the S4 pauses the video. Look back and the video starts playing again.

Here’s another way to control the S4 without touching the screen. You just make gestures above it, like a magician on stage. Air gestures don’t work everywhere on the S4, since apps have to be built to recognize them. So you may need to do some experimentation before you find the ones that do. At this writing, that includes email and the browser.

Quick glance. If your S4 is on a flat surface, facing up, with its screen turned off move your hand to above the sensor and you’ll be able to see various pieces of status information, like missed calls, unread messages, your battery power, and others.

This feature, which originated on the Samsung Galaxy Note II, lets you hover your finger over the S4 to get information from it. For example, hovering over a web page magnifies it, hovering over a picture in the Gallery opens it, hovering over a Calendar event reveals more details about it, hovering over a truncated text message reveals the full message, and so on.

Multi Window is an S4 feature you could easily miss—but don’t. It lets you do more than one thing on the phone at the same time. For example, watch a video while your also checking your email. What could be handier?

The Samsung Galaxy S4 Mini wants to offer a mid-size, affordable phone for those who think the full-size Samsung Galaxy S4 is a bit too big, a bit too pricey.

That the S4 Mini is brand new does not help. The phone is expected to go on sale in July 2013, while the larger Galaxy S4 was released back in April – what a difference a few short months can make.

However, the Mini is actually a bit chunkier than the S4 – by a full millimetre. This ensures that it doesn’t feel quite as slender as its big brother.

That smaller phones tend to be that bit chunkier makes sense, though, as they have to fit roughly the same internal components into a smaller area. The Galaxy S4 Mini only comes in black and white finishes, and has the same faux-metallic (i.e. plastic) finish as the full-size S4.

When the S4 launched, it came in two colours, white and blue. However, now you can get the phone in white, blue, black, red, brown and grey shades. Not all are widely available in the UK, though.

To go with the smaller body, the Galaxy S4 Mini has a smaller screen. It’s 4.3 inches across instead of a full five inches. Many people argue that 4.3 inches is a more sensible size because a body as large as the Galaxy S4’s is just too much for some people – saying that, Samsung’s clever design makes the S4 almost exactly the same width as the Galaxy S3.

The S4 also has a much more advanced screen than the S4 Mini. They use the same basic panel tech – Super AMOLED – but the resolution of the larger phone is much higher, both in plain numbers and relative to its screen inches.

In an IPS-based LCD display, 256dpi would give a pretty sharp image, but as the S4 Mini uses a PenTile display (PenTile is a kind of sub-pixel arrangement) its images won’t be as sharp. In other words, the S4 Mini screen isn’t just a step down in size, it’s a step down in quality too.

Continuing the trend of being cut down in every sense, the Galaxy S4 Mini has 8GB of internal memory while the Galaxy S4 has 16GB. Samsung also produces 32GB and 64GB editions of the 5-inch phone, but they’re not widely available in the UK.

The issue is that most apps can only be installed to the internal memory, not memory cards. However, the 5GB or so that will be accessible in the S4 Mini will be more than enough for most people.

MicroSD memory cards are dirt cheap these days, and 32GB ones can be had for well under £20. It’s a great solution if you want to use your Galaxy phone as a music or media player, and these files can happily live on a memory card.

The processor of the Galaxy S4 Mini is a lot less powerful than the Galaxy S4’s – more proof that this really isn’t just a shrunk-down S4. It uses a Snapdragon 400 dual-core chip running at 1.7GHz.

There is a little less RAM in the S4 Mini too, although not a great deal. The 3G version uses 1.5GB of RAM, which is actually more than features in the Galaxy S3, while the S4 has a full 2GB.

The interfaces of the Galaxy S4 and S4 Mini are almost identical, both based on a recent version of Android with the Samsung custom UI TouchWiz splattered on top.

Extra features include an exercise tracker, language translator, a custom speech recognition app and more. Most feature in both phones, including WatchON, which uses the IR transmitter to let you control your TV (and other equipment) with the phone. This is missing in the Galaxy S3 because the phone does not have an IR transmitter – it’s a neat extra for a lower-cost phone like the Galaxy S4 Mini.

The Samsung Galaxy S4 Mini has a camera that’s roughly a generation behind the Galaxy S4, with an 8-megapixel sensor rather than a 13-megapixel one – seen in most top-end Android phones of 2013.

As this point, we do not know if the S4 Mini uses the same sensor as the Galaxy S3, which also has an 8-megapixel camera. If it does, there shouldn’t be a massive disparity between the image quality of these two phones. As we saw in our comparison of the iPhone 5 and S4, there’s not a huge gulf between good 8-megapixel and 13-megapixel phone cameras.

They are similarly constrained by the tiny size of sensors of this type. We’ll be back with a full look at the S4 Mini’s photo capabilities when we get the chance to take the phone out for a camera test drive.

Like the S3 Mini before it, the Samsung Galaxy S4 Mini is not really a shrunken version of the S4. Its screen is not only smaller but worse too, its processor is slower, it has less storage and a weaker camera. However, in each field it packs enough of a punch to offer a solid mid-range Android experience. If you want everything the S4 has but in a smaller body, however, this isn’t it.

Despite the limitations, I’ve been enamored with taking pictures on the Flip 4. It’s worth shouting out the open palm gesture that Samsung has supported for years that makes hands-free triggering of the camera much easier. And I have to be honest — I mean specifically shooting selfies and content for social media featuring me (and my friends). The Flip 4 is also useful for my video calls with my parents in Singapore, eliminating the need for a phone stand. None of this is new to this year’s Flip, by the way. I just wanted to remind you how much fun and function you can get out of a regular-sized phone that folds.

It’s mostly intuitive and useful but, man, I have such a love-hate relationship with Flex mode. I vividly remember thinking that using the Flip with one hand while leaning back on my couch would be easier if Samsung added its Flex Mode panel to more apps so I could easily scroll through long posts or articles. I was wrong.

On the Flip 4, Samsung introduced a Touchpad feature to its Flex Mode panel, which you can force enable for most apps even if their developers didn’t design a specific layout. You’d use this like it were a laptop trackpad on the bottom of your screen: move your finger around to control a cursor, tap to click links and other elements and drag two fingers up or down to scroll. You can’t pinch to zoom, but honestly that’s not a laptop-like gesture I need here.

In theory, a lot of this makes sense. When you’re using one hand and holding the Flip slightly folded, reaching for elements on the top of the screen with your thumb can be tricky. The trackpad makes it easier to click things at the edge of the panel. But two-finger scrolling in one-handed use simply does not work, unless you somehow can balance the Flip with just three fingers and have the dexterity to use your remaining digits to swipe on the screen.

Those of us without Olympian-level finger gymnastic skills will probably need to leave Flex Mode to scroll. Trouble is, there is no easy way to summon this panel. Worse, it reappears if you straighten and refold the screen, or if you jump to another app and return. I’ve lost track of the number of times I’ve hit the X to dismiss Flex Mode, only to absentmindedly open Telegram to reply to a friend, and be presented with the black box again.

To be clear, this panel only appears if you’ve gone into the experimental Labs area in Advanced Settings to enable it for specific apps. Most people are unlikely to encounter it by default, and the Flex Mode layouts for customized apps like Gallery and Camera are fine.

The minimal functionality of the Flip 4 when it’s closed is a good way to partially unplug from distractions while still remaining reachable — kind of like using a pager (remember those?). Samsung’s new customizable clock face designs are adorable and make the device more attractive. I also appreciate being able to surreptitiously set a timer or snap a selfie when the Flip is small enough to hide in my palm — people are less aware of me taking my 900th selfie of the day when I’m using a tiny square instead of holding out a metal-and-glass slab of a phone.

Without increasing the size of the cover display, the company can’t really do much more. And I’m not sure I want Samsung to go bigger. A larger second screen would tax the battery, which is something the Flip 4 can barely spare. I’d much rather the company gave the next Flip better cameras.

That’s not to say the Flip 4’s cameras are bad. They’re actually surprisingly capable — especially the pair of 12-megapixel sensors on the outside. With larger 1.8-micron pixels than the Flip 3, the primary and ultrawide cameras both delivered impressively colorful and sharp pictures that rivaled the Pixel 6 Pro and iPhone 13 Pro in bright light.

Like the Galaxy S22 Ultra, the Flip 4’s pictures were warmer and more saturated than the Pixel’s, but less red than the iPhone’s. All three handsets produced similarly sharp pictures of buildings at sunset, though Samsung’s images were occasionally a little soft. But they weren’t anything egregious — the bark on a tree I shot against the sun wasn’t as crisp on the Flip for example. But I wouldn’t have noticed if I wasn’t pixel peeping looking for the differences.

As usual, Google has the upper hand at night, with windows on the Empire State Building looking tack sharp, but slightly blurrier on the Flip 4. I also prefer Google’s approach to Portrait mode. The Pixel 6 Pro is better at identifying outlines of subjects and applying a blur to everything else. Samsung’s system is still hit or miss and can look artificial.

Selfies I took in low light with the Flip 4 were similarly splotchy, but the Pixel and iPhone didn’t do much better in those situations anyway. I was pleasantly surprised by how sharp and warm the photos I captured with the Flip’s inside camera in daylight turned out, though. They looked more natural than the Pixel’s shots, and were about as good as the iPhone’s.

Like any mainstream flagship phone, the Flip 4 is equipped with the latest top-tier Snapdragon 8+ Gen 1 chip and has 8GB of RAM. After some initial hiccups while setting up the phone, during which the Flip 4 got noticeably warm, things got smoother. I never encountered any lag as I shot videos, livestreamed to Instagram, screen-recorded my friends’ Instagram Stories or posted photos. It did get hot again when I called my parents via Telegram, but otherwise the Flip mostly remained cool.

Thankfully the days of heavy-handed overlays like TouchWiz are mostly in the past, and Samsung’s phones now ship with fairly clean versions of Android and its One UI interface. There are pros and cons with this — I love Samsung’s Gallery app and the built-in video editor, for example. But I hate that Samsung occasionally still serves up ads in the notifications shade, showing you recommendations from the Galaxy App store. I also find that One UI doesn’t seem to understand Do Not Disturb mode, and frequently lets unnecessary alerts through. Still, the Flip 4’s software is not bloated and is fairly customizable, so you can alleviate some potential frustrations.

My biggest complaint about the Flip 3 was its dismal battery life, and it was the one thing keeping me from recommending it to a more mainstream user. With the Flip 4, Samsung not only used a larger 3,700mAh battery, but also a more power-efficient processor. The results aren’t astounding, but the Flip 4 generally lasts all day.

I usually take it out in the afternoon and come home past midnight with about 20 percent to spare. One Sunday, I took the Flip 4 to an early morning workout and ran around New York and New Jersey all day. By 10pm, it had dropped to 15 percent and was prompting me to enable battery-saving mode.

This is sort of pitiful compared to the battery life of the iPhone 13 Pro, Pixel 6 Pro and S22 Plus, which all stick around longer than a day. But given the Flip 4 has two screens, I’m willing to be more forgiving. Plus, when it came time to recharge the Flip, it didn’t take long — I usually got more than 40 percent of power in about 40 minutes.

On our video rundown test, the Flip 4 clocked 16 hours and 35 minutes, which is five hours more than the Flip 3 and, surprisingly, also more than the Nothing Phone 1. It’s even on par with the Galaxy S22+. Meanwhile, phones like the Pixel 6 and OnePlus 10T delivered results of more than 20 hours.

With its improved battery life and durability, the Flip 4 is a more practical phone than its predecessor and is the first of Samsung’s foldables that’s truly ready for the mainstream. Sure, there are a few minor inconveniences to put up with, like Instagram’s incompatibility with its aspect ratio or the fact that it has considerably less battery life than other phones at this price. But if you’ve been itching to see if a foldable phone might fit in your life (and your pocket), or if you’re a selfie aficionado, the Flip 4 will be a satisfying purchase.

Retina Display is a brand name used by Apple for its series of IPS LCD and OLED displays that have a higher pixel density than traditional Apple displays.trademark with regard to computers and mobile devices with the United States Patent and Trademark Office and Canadian Intellectual Property Office.

The Retina display debuted in 2010 with the iPhone 4 and the iPod Touch (4th Generation), and later the iPad (3rd generation) where each screen pixel of the iPhone 3GS, iPod touch (3rd generation), iPad 2 was replaced by four smaller pixels, and the user interface scaled up to fill in the extra pixels. Apple calls this mode HiDPI mode. In simpler words, it is one logical pixel = four physical pixels. The scale factor is tripled for devices with even higher pixel densities, such as the iPhone 6 Plus and iPhone X.

The Retina display has since expanded to most Apple product lines, such as Apple Watch, iPhone, iPod Touch, iPad, iPad Mini, iPad Air, iPad Pro, MacBook, MacBook Air, MacBook Pro, iMac, and Pro Display XDR, some of which have never had a comparable non-Retina display.marketing terms to differentiate between its LCD and OLED displays having various resolutions, contrast levels, color reproduction, or refresh rates. It is known as Liquid Retina display for the iPhone XR, iPad Air 4th Generation, iPad Mini 6th Generation, iPad Pro 3rd Generation and later versions,Retina 4.5K display for the iMac.

Apple"s Retina displays are not an absolute standard for display sharpness, but vary depending on the size of the display on the device, and at what distance the user would typically be viewing the screen. Where on smaller devices with smaller displays users would view the screen at a closer distance to their eyes, the displays have more PPI (Pixels Per Inch), while on larger devices with larger displays where the user views the screen further away, the screen uses a lower PPI value. Later device versions have had additional improvements, whether an increase in the screen size (the iPhone 12 Pro Max), contrast ratio (the 12.9” iPad Pro 5th Generation, and iMac with Retina 4.5K display), and/or, more recently, PPI count (OLED iPhones); as a result, Apple uses the names “Retina HD display", "Retina 4K/5K display", “Retina 4.5K display", "Super Retina HD display", “Super Retina XDR display”, and "Liquid Retina display" for each successive version.

When introducing the iPhone 4, Steve Jobs said the number of pixels needed for a Retina display is about 300 PPI for a device held 10 to 12 inches from the eye.skinny triangle with a height equal to the viewing distance and a top angle of one degree will have a base on the device"s screen that covers 57 pixels. Any display"s viewing quality (from phone displays to huge projectors) can be described with this size-independent universal parameter. Note that the PPD parameter is not an intrinsic parameter of the display itself, unlike absolute pixel resolution (e.g. 1920×1080 pixels) or relative pixel density (e.g. 401 PPI), but is dependent on the distance between the display and the eye of the person (or lens of the device) viewing the display; moving the eye closer to the display reduces the PPD, and moving away from it increases the PPD in proportion to the distance.

The displays are manufactured worldwide by different suppliers. Currently, the iPad"s display comes from Samsung,LG DisplayJapan Display Inc.twisted nematic (TN) liquid-crystal displays (LCDs) to in-plane switching (IPS) LCDs starting with the iPhone 4 models in June 2010.

Apple markets the following devices as having a Retina display, Retina HD display, Liquid Retina display, Liquid Retina XDR display, Super Retina HD display, Super Retina XDR display or Retina 4K/5K/6K display:

Reviews of Apple devices with Retina displays have generally been positive on technical grounds, with comments describing it as a considerable improvement on earlier screens and praising Apple for driving third-party application support for high-resolution displays more effectively than on Windows.T220 and T221 had been sold in the past, they had seen little take-up due to their cost of around $8400.

"to our eyes, there has never been a more detailed, clear, or viewable screen on any mobile device. Not only are the colors and blacks deep and rich, but you simply cannot see pixels on the screen…webpages that would be line after line of pixelated content when zoomed out on a 3GS are completely readable on the iPhone 4, though the text is beyond microscopic."

Raymond Soneira, president of DisplayMate Technologies, has challenged Apple"s claim. He says that the physiology of the human retina is such that there must be at least 477 pixels per inch in a pixelated display for the pixels to become imperceptible to the human eye at a distance of 12 inches (305 mm).Phil Plait notes, however, that, "if you have [better than 20/20] eyesight, then at one foot away the iPhone 4S"s pixels are resolved. The picture will look pixelated. If you have average eyesight [20/20 vision], the picture will look just fine... So in my opinion, what Jobs said was fine. Soneira, while technically correct, was being picky."

The first smartphone following the iPhone 4 to ship with a display of a comparable pixel density was the Nokia E6, running Symbian Anna, with a resolution of 640 × 480 at a screen size of 62.5mm. This was an isolated case for the platform however, as all other Symbian-based devices had larger displays with lower resolutions. Some older Symbian smartphones, including the Nokia N80 and N90, featured a 2.1 inch display at 259 ppi, which was one of the sharpest at the time. The first Android smartphones with the same display - Meizu M9 was launched a few months later in beginning of 2011. In October of the same year Galaxy Nexus was announced, which had a display with a better resolution. By 2013 the 300+ ppimark was found on midrange phones such as the Moto G.Samsung Galaxy S4 and HTC One (M8) had 1080p (FHD) screens around 5-inches for a 400+ PPI which surpassed the Retina density on the iPhone 5. The second major redesign of the iPhone, the iPhone 6, has a 1334 × 750 resolution on a 4.7-inch screen, while rivals such as the Samsung Galaxy S6 have a QHD display of 2560 × 1440 resolution, close to four times the number of pixels found in the iPhone 6, giving the S6 a 577 PPI that is almost twice that of the iPhone 6"s 326 PPI.

The larger iPhone 6 Plus features a "Retina HD display", which is a 5.5-inch 1080p screen with 401 PPI. Aside from resolution, all generations of iPhone Retina displays receive high ratings for other aspects such as brightness and color accuracy, compared to those of contemporary smartphones, while some Android devices such as the LG G3 have sacrificed screen quality and battery life for high resolution. Ars Technica suggested the "superfluousness of so many flagship phone features—the move from 720p to 1080p to 1440p and beyond...things are all nice to have, but you’d be hard-pressed to argue that any of them are essential".

Due to the peculiar diamond Sub-Pixels layout found in the iPhone X, iPhone XS and iPhone XS Max, the actual density of the Red and Blue Sub-Pixels is lower than that of the Green Sub-Pixels, being reportedly 324 Sub-Pixels per inch.

The Samsung Galaxy S4 is an Android smartphone produced by Samsung Electronics as the fourth smartphone of the Samsung Galaxy S series and was first shown publicly on March 14, 2013, at Samsung Mobile Unpacked in New York City. It is the successor to the Galaxy S III, which maintains a similar design, but with upgraded hardware, more sensors, and an increased focus on software features that take advantage of its hardware capabilities—such as the ability to detect when a finger is hovered over the screen, and expanded eye tracking functionality, it was released the previous year.LTE Advanced mobile network standard (model number GT-i9506). The T-Mobile version of the Galaxy S4, named the model (SGH-M919), was released the same month. The phone"s successor, the Samsung Galaxy S5, was released the next year.

The Galaxy S4 is among the earliest phones to feature a 1080p Full HD display, 1080p front camera video recording, and among few to feature temperature and humidity sensors and a touch screen able to detect a floating finger.

The Samsung Galaxy S4 uses a refined version of the hardware design introduced by the Samsung Galaxy S III, with a rounded, polycarbonate chassis and a removable rear cover. It is slightly lighter and narrower than the Samsung Galaxy S III, with a length of 136.6 mm (5.38 in), a width of 69.8 mm (2.75 in), and a thickness of 7.9 mm (0.31 in). At the bottom of the device is a microphone and a micro USB port for data connections and charging; it also supports USB-OTG and MHL 2.0. Near the top of the device are a front-facing camera, an infrared transmitter for usage as universal remote control,proximity, and ambient light sensors, and a notification LED. In particular, the infrared sensor is used for the device"s "Air View" features.headphone jack, secondary microphone and infrared blaster are located at the top.plastic leather backing, similar to the Galaxy Note 3.

The S4"s 5-inch (130 mm) 1080p Full HDpredecessor, and also features a Pen Tile RGBG matrix. The pixel density increased from 306 to 441 ppi, surfaced with Corning Gorilla Glass 3. An added glove mode option increases touch sensitivity to allow detecting touch input through gloves. The Galaxy S4 is Samsung"s first and one of the earliest mobile phones of all time to feature a 1080p display.

Unlike previous models, the S4 does not contain FM radio support, citing the increased use of online media outlets for content consumption on mobile devices.

While the front cameras of the Galaxy S3 and Galaxy Note 2, both released in 2012, are only able to capture videos at up to 720p HD resolution, the front camera of the Galaxy S4 allows 1080p Full HD video recording for the first time in any Samsung mobile phone.

Unlike the predecessor, the S4 is also equipped with a hall sensor for the S View cover, a self-capacitivetouch screen layer for Air View and thermometer and hygrometer sensors,Galaxy Note 3 out of all historical Samsung flagship devices are equipped with.

Galaxy S4 models use one of two processors, depending on the region and network compatibility. The S4 version for North America, most of Europe, parts of Asia, and other countries contains Qualcomm"s Snapdragon 600 system-on-chip, containing a quad-core 1.9 GHz Krait 300 CPU and an Adreno 320 GPU. The chip also contains a modem which supports LTE.Exynos 5 Octa system-on-chip with a heterogeneous CPU. The octa-core CPU comprises a 1.6 GHz quad-core Cortex-A15 cluster and a 1.2 GHz quad-core Cortex-A7 cluster.IT tri-core PowerVR SGX 544 graphics processing unit (GPU). Regional models of the S4 vary in support for LTE; for Exynos 5-based models, while the E300K/L/S versions support LTE, with the Cortex-A15 also clocked at 1.6 GHz.

On 24 June 2013, a variant supporting LTE Advanced (model number GT-i9506), the first commercially available device to do so, was announced for South Korea.Samsung Galaxy S4 LTE+, but only with Telekom and Vodafone branding.CPU (Snapdragon 800) and GPU (Adreno 330) hardware as the Galaxy Note 3 SM-N9005,

The S4 comes with either 16 GB, 32 GB, 64 GB of internal storage, which can be supplemented with up to an additional 64 GB with a microSD card slot.NFC-enabled battery.

Head tracking features have been extended on the S4, summarized as "Samsung SmartScreen". The new "Smart Scroll" feature can be used to scroll while looking at the screen by slightly tilting head or phone forward or backward,Smart Pause" allows the video player to pause videos if the user is not looking at the screen. "Smart Rotation" tracks the facial orientation using the front camera to match the screen rotation and "Smart Stay" prevents entering stand-by mode by deactivating display time-out while the user is looking at it.

These interaction features were later inherited by the Galaxy Note 3 and the Galaxy S5, but most of those features were gradually removed from Samsung"s flagship phones released afterwards.

The camera app implements numerous new features (some of which were first seen on the Galaxy Camera), including an updated interface, and new modes such as "Drama" (which composes a moving element from multiple shots into a single photo), "Eraser" (which takes multiple shots and allows the user to remove unnecessary elements from a picture), "Dual Shot" (which uses the front-facing camera for a picture-in-picture effect), "Sound and Shot" (which allows the user to record a voice clip alongside a photo), "Animated Photo", and "Story Album" among others. Burst shots at full resolution are supported, but capped at twenty consecutive pictures at any selected resolution.

In addition, the Galaxy S4 is able to capture 9.6 Megapixel (4128×2322) still photos during 1080p video recording, even with enabled digital video stabilization.

While the camera viewfinder user interface of the 2012"s Samsung Galaxy S3, Galaxy Note 2, the competing iPhone 5 and iPhone 5s require switching between photo and video modes, the viewfinder of the Galaxy S4 camera software shows the buttons for both photo and video capture simultaneously. The virtual buttons for video recording, photo capture and camera modes have a metallic texture.

The "Group Play" feature allows ad hoc sharing of files between Galaxy phones, along with multiplayer games and music streaming between S4 phones. The S4 also introduces Knox in the Android 4.3 update, a suite of features which implements a sandbox for enterprise environments that can co-exist with a user"s "personal" data. Knox incorporates use of the ARM TrustZone extensions and security enhancements to the Android platform.

The TouchWiz keyboard application on the Galaxy S4 has a built-in clipboard feature that allows holding up to twenty items such as text and screenshots.

Other new pre-loaded apps include WatchOn (an electronic program guide that can utilize the S4"s infrared transmitter to be a remote control), S Translator, the workout tracker S Health, S Voice Drive, S Memo, TripAdvisor, and an optical character recognition app.

In November 2013, Samsung began rolling out an update to Android 4.3 for the S4, notably adding the Bluetooth low energy support needed for compatibility with the Galaxy Gear smartwatch. However, Samsung halted the rollout following reports from Galaxy S III users that Samsung"s version of 4.3 had caused instability and increased battery usage.

In February 2014, Samsung began rolling out an update to Android 4.4.2 "KitKat" for the S4; the update adds user interface tweaks such as a camera shortcut on the corner of the lock screen, options for setting default launcher and text messaging applications, support for printing, and a new location settings menu for tracking and controlling the use of location tracking by apps.OEMs such as Samsung previously modified their distributions of Android to retain the previous behavior, allowing applications to have unlimited access to SD card contents.

In January 2015, Samsung began rolling out an update to Android 5.0.1 "Lollipop" in Russia and India, an update which brings all the features of Lollipop, such as enhanced performance and lockscreen, including a refined interface with a flatter and geometric look, as seen on the Galaxy S5.

Several different model variants of the S4 are sold, with most variants varying mainly in handling regional network types and bands. To prevent grey market reselling, models of the S4 manufactured after July 2013 implement a regional lockout system in certain regions, requiring that the first SIM card used on a European and North American model be from a carrier in that region. Samsung stated that the lock would be removed once a local SIM card is used.

At the Google I/O 2013 keynote, Samsung and Google revealed that an edition of the U.S. S4 would be released on June 26, 2013 through Google Play, with the HTC One M7, Sony Xperia Z Ultra, Motorola Moto G, and HTC One M8 releasing later on.Android 4.2.2, the phone later updated to 4.4.4, with Samsung provided updates;Nexus devices) and supports LTE on AT&T and T-Mobile"s networks.

At retail, the S4 is bundled with a USB cable, AC adapter, and in-ear headphones.hall effect sensor), the time and battery are displayed in this cover"s window area.

While some users considered all new Galaxy S4 features innovative and legitimately useful, others called them feature creepgimmicks.Smart Pause, Smart Rotation, Smart Scroll, Air View, Air gesture, Story Album and Temperature and humidity sensors.

Additionally, the Galaxy S4 is equipped with an “easy mode” that hides many features and increases the size of on-screen elements for easier readability for novice mobile phone users.

The S4 received many positive reviews, though some criticism. Gigaom"s Tofel says he would recommend the S4 "without hesitation" and says that it"s "Samsung"s defining phone".ReadWrite"s Rowinski described the phone as a "solid" and "first-rate smartphone", but criticised Samsung"s use of "bloatware, pre-loaded apps and features that you will likely never use".

Technology journalist Walt Mossberg described the S4 as "a good phone, just not a great one". Mossberg wrote: "while I admire some of its features, overall, it isn’t a game-changer." He criticized the software as "especially weak" and "often gimmicky, duplicative of standard Android apps, or, in some cases, only intermittently functional." He urged readers to "consider the more polished-looking, and quite capable, HTC One, rather than defaulting to the latest Samsung."

Critics noted that about half of the internal storage on the S4"s 16 GB model was taken up by its system software, using 1 GB more than the S III and leaving only 8.5 to 9.15 GB for the storage of other data, including downloaded apps (some of which cannot be moved to the SD card). Samsung initially stated that the space was required for the S4"s new features, but following a report regarding the issue on the BBC series

The S4 sold 4 million in 4 days and 10 million in 27 days making it the then fastest selling smartphone in Samsung"s history (this has been eclipsed by the Galaxy S5).Galaxy S II took 55 days and the Galaxy S took 85 days.

In the UK, companies which sold the S4 have varied in their reactions to claims by worried customers for replacement batteries under the Sale of Goods Act. Amazon, for example, have simply refunded part of the purchase price to allow for the cost of a replacement battery. O2 however insist that the complete phone, with the faulty battery, be returned to them so that they in turn can send it to Samsung to consider the claim.
