DisplayTester makes it possible to test almost every aspect of your device"s LCD/OLED screen. Using Google Cast it is possible to test the display quality of your TV. It is designed to allow full screen testing also on devices with soft keys (hiding the soft keys in ICS and later, immersive mode in KitKat and later).

When the soft keys are hidden it is not easy to advance to the next screen: First tap to make the buttons appear, then a quick swipe for the next screen before the buttons are hidden again.

Besides obvious features like a touchscreen and biometric sensors, the modern smartphone comes with an array of state-of-the-art hardware in the form of various sensors that help your device sense the environment around it. And if you have a Samsung handset, chances are, you have a handy feature built in that enables you to check if these sensors are functioning 100 percent.

Unbeknownst to a lot of Samsung fans, most Galaxy phones have a secret diagnostic mode built in which can be accessed simply by inputting a little-known code. Best of all, this feature is extremely easy to access and is a handy way of testing out a new or used phone to ensure it"s in perfect running order before you commit to buying it.

Below are the following tests you can perform on your Samsung handset once you"ve input the code and entered HwModuleTest mode. Please note that some may be missing screenshots due to security reasons or the nature of the tests.

To check if your phone"s receiver is working properly, tap on the "Receiver" button to commence testing. Doing so should take you to a white screen, accompanied by a clearly audible dial tone. Once you"re satisfied, simply tap on the back button twice to go back to the main test page.

"Vibration" tests out your phone"s vibration motor. Your screen will go black once you tap on the "Vibration" button, accompanied by a constant vibration. Tap on the screen once to exit this test and go back to the main test screen.

Tapping on the "Sensor" button will yield a test page for a host of sensors — namely the accelerometer, proximity sensor, barometer, light sensor, gyroscope, magnetic sensor, HRM, and fingerprint scanner. I"ll go over all eight of these submenus in separate sections below.

Tapping on the "Sleep" button will test out your device"s sleep functionality. Doing so should immediately put your phone into sleep mode. Once done, wake your phone as you normally would, and you"ll automatically be taken back to the main diagnostic page.

Tap on the "Speaker" button if you want to test out your handset"s audio output, which in turn plays a sample song that you can listen to. Once you"ve verified that your speakers are good, simply tap on the "Speaker" button again to end the test.

The LED test checks for the functionality of your device"s LED notification light. Running the test is straightforward — simply tap on the "LED" button, then tap on the screen to change the LED"s color from red, to green, and finally to blue. Tap on the screen one last time to end the test and go back to the main diagnostics page.

"Low Frequency" tests out your phone"s earpiece, and tapping on the button to commence testing will bring you to the "Low Frequency Test" page. From there, tap on 100 Hz, 200 Hz, and 300 Hz and place your ear against the phone"s earpiece each time you select a frequency to check for low buzzing noise. Once you"ve completed the tests, you can exit back to the main diagnostics page by tapping on the back button twice.

The Hall IC sensor detects magnetic fields and is primarily used to detect magnetic flip covers to automatically put the phone to sleep when a magnet within the flip cover touches the phone. The test itself doesn"t do much and simply gives a confirmation that the Hall IC functions properly.

Last but not least, the "Iris Camera Test" tests out the infrared iris camera that"s used to unlock your device. Tapping on the button pulls up your iris camera for you to align your eyes with, and will instantly close and go back to the main diagnostic page once it"s successfully scanned your iris.

Once you"re done performing your diagnostic tests, you can now exit HwModuleTest Mode. To do so, simply tap on the back button twice to go back to your phone"s dialer, then exit from there as you normally would. You"re now free to go on with the rest of your day, knowing that all is right with your beloved device!

The most common issues of Android screens are dead and stuck pixels. Dead pixels occurs when small color pigments of your screen gets busted, resulting to a black spot on your screen, while stuck pixels are color pigments of the display that are frozen, unable to change to other colors like it normally should. These issues can easily be avoided if you can detect it while the problem is still not that severe. That"s why testing your LCD display is outright important and needs to be done frequently to avoid any issues from worsening.

A good monitor is expensive. But its impact will be lost if you don"t take the pain to carefully (and intermittently) calibrate your monitor. The colors on the screen may not be the exact match of what they actually are.

Graphics professionals will pick up serious color accuracy test tools for the job, like the Datacolor Spyder5Elite S5EL100 Monitor Calibration System. Some of you will go with the default monitor calibration software built into the OS. But we can also take some online help from these simple monitor calibration websites that have existed for a long time.

To open the Display Color Calibration tool, press Windows + S or open the Start menu, search for "calibrate display color," then open the matching result, and follow the on-screen instructions.

To manually open the ClearType Text Tuner, press Windows + S, search for "adjust ClearType text," then follow the on-screen instructions. On each of five screens, you"ll select the text samples that look best to you.

The site offers this simple one-page monitor calibration tool to adjust the brightness and contrast of your screen thanks to the gray scale tones. The idea is to tweak the monitor settings (or buttons) so that you can clearly distinguish the transition of tones from true black to true white. After calibration, the blacks should look black and without any hint of gray.

The instructions start off by telling you to dim the lights and hit F11 for viewing the gray scale chart in full-screen mode. Observe your monitor from your normal viewing distance.

The Lagom LCD Monitor Test Pages are a far more comprehensive set of tools than Photo Friday. The site includes a series of test patterns that start from checking contrast to checking for response times of your monitor. It is recommended to go through the tests in the order they are placed.

For instance, use the first few images to check brightness, contrast, and sharpness. With those set, use a latter test like the “Viewing Angle” to see if the display changes brightness or colors in the corners.

For a beginner, it might seem overwhelming. But, the test patterns come with helpful explanations. The developer also states that you can put the images on a USB drive and try them in the computer store when shopping for an LCD monitor. A 120 KB ZIP file download is included.

The Online Monitor Test website has a range of interactive tests to fix your screen colors. The menu appears when you move your mouse to the top. It starts off with a test that checks the brightness and contrast across the B/W tonal spectrum. It is similar to the test we covered on the Photo Friday website.

Next, the Color Range test checks if your monitor can smoothly produce color gradients. From the menu, you can pick different color charts. Look for “ghost images” or image trails in the Trailing test. Move the box across the screen and check if any trails are produced. The controls and options to change the color and shape of the box are placed at the bottom.

The Homogeneity test helps to pinpoint damaged pixels and faulty monitors with backlight bleeding. 1:1 Pixel mapping and testing for a blurring of Text are the last two tests on the lineup. While the former is not so much an issue with LCD computer monitors, the latter is worth a tryout if you feel that screen text is not crisp enough.

Note: We linked to the test version that requires JavaScript above. Most browsers won"t support the Flash versions of the test, but if you"d prefer to download the executable (no browser plugin required), visit the Online Monitor Test homepage

Remember, we were talking about Gamma values just a while back? Well, this whole page and the test associated with it is devoted to it. The importance and process are clearly laid out, and it"s helpful for any tyro. The most important takeaway is that color saturation and hue change with gamma values.

The author also provides a series of “Gamagic” test patterns you can use to calibrate your monitor. Fall back on your eyes and adjust the gamma setting with the monitor controls until all the squares match up with their backgrounds as closely as possible.

This single page screen calibration chart has few of the test images we have already covered in the earlier tools. Go through the color, gray scale, and gamma adjustments.

That annoying dead pixel on your TFT, OLED, or LCD screen might just be stuck and easy to fix. We"ll show you how to do it. You can still return your monitor if this doesn"t work; nothing we recommend here will void your warranty.

Yes, you should test any new monitor for bad pixels. You can simply run your screen through a palette of basic colors, as well as black and white in full-screen mode using a tool like EIZO Monitor Test.

EIZO Monitor Test is an online tool that lets you find and eventually fix stuck pixels. It packs many options into a single test window, but it"s easy to use once you have an overview.

To test your screen, check all the boxes you want to include in your test. We recommend the default setting of having all boxes checked. If you"re testing multiple monitors, you can open the test on an additional monitor. When you"re ready, click Start test to launch the full-screen test window.

Below you see the first test pattern. Each screen has an explainer in the bottom right detailing what you should look for. Next, you"ll see a menu that lets you go from one test to the next on the left. Move through the black and white screens and all the solid colors (green, blue, and red) and check our screen. To exit, press the ESC key or the exit symbol in the top right.

This is a very thorough test not only meant to identify bad pixels but also powerful enough to test the quality of your monitor. Unfortunately, with Flash no longer supported by most browsers, you"ll probably have to use the executable version to make it work.

Move the mouse to the top of the test window, and a menu will appear. There is an info window that you can turn off with a button in the top right corner of the menu. Then click on the Homogenuity test point and move through the three colors as well as black and white.

The tool will load a black browser window with a square of flashing pixels. Press the green button in the bottom right to go full-screen. Drag the flashing square to where you found the stuck pixel and leave it there for at least 10 minutes.

Let it run through all colors in Auto mode to spot whether you have any weird pixels on your screen. If you do, start the fix, which will rapidly flash your entire screen with black, white, and basic color pixels.

This works because, in a stuck pixel, the liquid in one or more of its sub-pixels has not spread equally. When your screen"s backlight turns on, different amounts of liquid pass through the pixel to create different colors. When you apply pressure, you"re forcing the liquid out, and when you release the pressure, chances are the liquid will push in, spreading around evenly as it should.

When all attempts to revive your bad pixel fail, the next best thing you can do is to make peace with it. One ugly pixel won"t break your screen, and eventually, you"ll forget about it. If the defect affects more than a single pixel, however, or just bothers you a lot, you can always replace your monitor.

Bright or dark sub-pixels can occur during the production of the LCD Monitor panel but does not affect the LCD Monitor functionality. The customer may notice the bright or dark spots if the film of the liquid crystal does not perform as expected while customers uses the LCD monitor. However, this is not considered a defect unless the number of bright and dark subpixels exceeds the maximum allowable threshold (...)

Should all of these approaches fail to fix your dead pixel warrior, at least you"ll now know it"s not simple to fix, and, you might actually have to replace the screen.

Visuals on a screen are created by displaying multiple still images in sequence. The faster these sequences pass by, the more convincing the illusion, making the video look smoother.

This is where the refresh rate comes in. Simply put, the refresh rate of a display is the number of frames it can show every second. The higher the refresh rate, the better the picture quality you get. This is why you need to test your display and determine if its refresh rate is actually enough for your gaming or video needs.

This is one of the easiest tests to run, and also one of the most accurate. Just open the site and let it work its magic. TestUFO will automatically sync with your browser and check the refresh rate of the monitor. The results are displayed in the middle of the screen.

It’s advised to close all other running programs and browser tabs while running the test to minimize any interference. In case the internet is choppy, the tool will display a warning at the bottom. Wait until it shows a green “Ready” to confirm the results.

TestUFO also offers other tools to test additional parameters of your monitor. For example, you can check your display for frame skipping, which comes in handy if you are overclocking your monitor.

Simple and minimalistic, this test does what it says: display the refresh rate of your monitor in Hertz (Hz). The test is notable for how quickly it works, giving you a result in mere seconds. This is much faster than most similar tools in the market.

It’s an improved version of an older tool called Vsync Tester (which might still be better for older devices). Its accuracy is unmatched, giving you the refresh rate in six decimal points, which is leagues ahead of the competition.

This tool is especially useful when comparing multiple displays, as most screens will show roughly the same values. The additional precision allows for a better comparison to be made.

This nifty little tool can test your display and quickly determine its refresh rate. While it shows results only to a single decimal point, the value is determined in seconds.

Display Test works on most browsers including Apple WebKit and Mozilla’s Gecko-based offerings, apart from Chrome, of course. It also has a better UI than most such tools, making it easy to use and understand.

We have listed this on number four, but this is probably the most comprehensive tool on the list. The Eizo Monitor Test doesn’t just test the refresh rate of your monitor, but everything about it.

Defective pixels, color distances, sharpness, viewing angle – this tool tests your monitor on all important technical aspects. It is also fully customizable, allowing you to choose which of the tests to run, so you can just use the refresh rate test if in a hurry.

These features make the Eizo monitor test a very helpful asset in diagnosing monitor issues. You should use the site to check your monitor from time to time to ensure that it’s functioning properly.

For a more holistic look at your monitor, you must use the Eizo monitor test. It will help in testing your device for all sorts of visual issues, making sure it is working properly.

The Android emulator can only be named with uppercase or lowercase letters (A-z), numbers from 0 to 9, periods (.), underscores (_), parentheses ( () ), dashes (-), and spaces.

The online touch screen tester is a free to use tool, that can instantly test out a smartphone’s touch, and highlights any defects that it may find. The tool uses simple touch response mechanism to work.

It takes in the input from a part of the touch screen and displays the output to the user. This tool makes testing touch screens, a whole lot easier by introducing features that clearly point out the defect in your handheld’s touch screen.

The area of the touch screen where the touch is detected is marked with a grid, which confirms that the device has indeed, detected the touch. The tool uses the Cartesian coordinate system to show the exact location of the touches on your device. It does the coordinates as x and y, whose valid change in real time as you move your fingers through the touch screen.

Yes, that’s right. Most users want to check whether their device supports multi-touch feature. Well this test tool is here to solve all your problems. It can easily detect multiple touches on the display and uses a different colors grid to show the different touches.

The test tool can detect up to 10 different touches at a time, so you can easily find out the maximum number of touches, that your device supports. Each touch displays until your device does not support any more of them.

Tools has multiple modes for checking your touch screen in every possible way. It features a simple real-time mode where the touches displays in real time only and disappear once the touch is no longer sens.

Touch screen test tool also features another mode where the touch displays but it does not disappear when the touch is no longer sensed, but rather stays in the area where the touch is last detected, this helps in finding the defective touch spot with pinpoint accuracy.

The test tool features an option to clear the screen of previous touches upon shaking the device. This small feature may not seem like much but your can easily check your device’s G-sensor for defects with this option. If the screen does not clear upon shaking, then the G-Sensor may be faulty.

With its best test algorithms, your can easily check your digitizer touch for any defects instantly. And reports the defect in different ways, depending on the mode selected.

Let’s say you have an iPhone and want to see why it’s experiencing performance problems. Or maybe you want to buy a used iPhone and see if there are any problems to know about. Or perhaps as a reseller, you want to make sure the phone you’re selling is in optimum condition to maximize the price for the iPhone and minimize returns and future repair problems. There are many reasons to run a complete phone hardware diagnostic test. Ultimately, these tests let you know how well the device operates and what problems need to be addressed.

Like all Apple products — whether it’s your Mac, iPad, or Apple Watch — iPhones tend to be closed devices. You might have detailed information about battery health, performance, and history — but that’s about it. It doesn’t have the kind of diagnostic tools you’ll find on some Android phones.

With certain Android devices, you can dial in codes in the phone’s app dialer — such as *#0*# and *#*#4636#*#* — to access a hidden diagnostic menu or usage information menu. You can also dial *#*#0*#*#* to test the LCD screen or  *#*#2664#*#* for a touch-screen test.

However, you either need a third-party app, remote help, or extensive Apple Customer Support assistance for an iPhone. Let’s review the different ways to run an iPhone hardware test.

You can also do remote mobile testing with your iPhone.You don’t need the phone itself for this testing; just its IMEI (International Mobile Equipment Identity) number. The IMEI is a unique 15-digit number that enables your phone to access cell phone networks. It can also provide you with the complete history of the iPhone, including whether it has ever been stolen or previously  refurbished.

Another way to find out about the condition of your device is to run a third-party testing phone app. You have various choices, and some may include insurance, trade-in, and repair shop location features. Instead of relying on guesswork to find out what is wrong with your phone, these diagnostic testing apps can scan your device to find out what needs to be fixed or point you in the right direction to find a solution.

This service provides an easy way for used phone resellers to do full tests on high volumes of devices, ensuring they are in optimum working condition. The Phonecheck software will scan phones for dozens of test points in less than two minutes, providing notifications about the iPhone hardware test, signal strength test (for Wi-Fi, Bluetooth, and cell signal), microphone functionality, speakers, and more.

You can print out a certification to go with the phone at the end of a test, giving your customers buying confidence. Check out Phonecheck’s complete device processing solution as the best way to build trust between buyers and sellers in the secondary market.

Running a reliable diagnostics test on an iPhone is important to build trust and transparency between the buyer and seller. Without hidden defects, a phone can be bought and sold with confidence.

As an iPhone reseller, it’s important to run a realistic diagnostics test to ensure the devices you buy and sell are running optimally. A diagnostic report can help you make necessary repairs, command the best prices, and provide customers with the peace of mind that comes through a device certified in good working order. Doing this before buying or selling an iPhone strengthens the relationship between buyer and seller.

With a diagnostic test, you can identify what’s wrong with the phone, so you can repair it or let the customer know about the defect so they can buy with their eyes wide open. A test can also reveal if there is sensitive personal information still left on the phone that needs to be wiped clean for security’s sake.
