(Pocket-lint) - With the top end of the market practically sewn up, Samsung is looking to push that success into the middle of the pack with the Samsung Galaxy S III Mini. It looks like the company"s top phone, but the specs see it as more of a replacement for the Samsung Galaxy S Plus.

But can this type of phone now survive? Does the mid-range proposition still have any appeal when Google"s own Nexus 4 undercuts it in price? And does this "mini" phone bring any of the luxury of its big brother, the Samsung Galaxy S III?

There"s a lot to like about the Samsung Galaxy S III Mini. The range of tweaks that Samsung has layered in is impressive, it looks good and it"s a flexible phone with the option to expand the memory and swap the battery if you need to.

That"s something of a problem, because throughout the time we’ve been using the SGS3 Mini, it has been the keyboard, or the lag in navigation, or unexpected delays, that we"ve really noticed.

So is the Samsung Galaxy S III Mini for you? If you"re not expecting your phone to fly around every button press then perhaps: it"s well made, it looks nice and it offers plenty out of the box, but we think it could and should be a better performer.

In the design department, there"s lot that"s positive to say about the Samsung Galaxy S III Mini. Finished in white, it looks like its bigger sibling at first glance, and that"s no bad thing.

The curved back of the SGS3 Mini fits nicely in the hand and it"s small enough to sit in the palm with enough grip to keep things secure. The compact size - measuring 121.55 x 63 x 9.85mm - means it"s easy to use with one hand as you can easily get all over the display and to all the buttons

Sitting at the core of the Samsung Galaxy S III Mini is a dual-core 1GHz processor and 1GB of RAM. There is 8GB of internal storage but. as we said, a microSD card slot to give you more space if you need it.

Conversely the Samsung Galaxy S III Mini doesn"t struggle with running apps. They might take a touch longer to open, which is acceptable, but once in we didn"t have a problem. Games like Angry Birds Star Wars of Where"s My Perry? played without issue. This type of device is never going to be a gaming powerhouse, but for much of the casual gaming that takes place on mobile devices it"s well suited.

The 4-inch AMOLED display on the Samsung Galaxy S III Mini is pretty good, with an 800 x 480 pixel resolution. That gives you a pixel density of 233ppi. It"s sharp enough and everything looks refined enough, if lacking the visual flourish of the latest displays with higher resolutions.

While we feel the LCD displays of recent devices are better than AMOLED, the display here acquits itself well. AMOLED brings a vibrancy and saturation to colours, which, while not entirely authentic, gives some punch to things. Images display bolder colours, but the whites are a touch on the yellow side.

The Samsung Galaxy S III Mini gets several of the fancy features that debuted with the SGS3 back in May 2012. Visually the default theme of the SGS3 Mini looks remarkably similar and it"s nice to find that Samsung has brought things like the pop-out video player to this mid-tier device.

Samsung also offers its own app store in Samsung Apps and has pre-integrated some of the apps into the SGS3 Mini, which we don"t really like. The Gallery has an edit option for your photos, but there"s no app to support this function. Instead you"ll be redirected to Samsung Apps and prompted to open an account before you can access that app, which feels like a sneaky way of pushing you into an additional service.

The Samsung Galaxy S III Mini is a great music player and we were more than happy with the sound quality through a decent pair of headphones. The external speaker is loud and offers respectable quality playback too.

On the video front, as we mentioned, the Samsung Galaxy S III Mini is a nice device for watching video. The display means things look a little too saturated, but gives content plenty of punch. It"s not the most powerful phone around, but it will play 720p content (as well as capture it), but to save space you"re better off feeding it SD content that matches the screen"s resolution.

There"s a 5-megapixel camera on the rear of the Samsung Galaxy S III Mini and a 0.3-megapixel camera on the front. The front camera performance is typical of front-facing cameras, but as it"s mostly designed for video calling, it"s adequate.

There"s plenty to tweak too, like ISO or metering, but some of this might go a little too far, when most just pull out their phone and snap off a shot in auto settings.The result are pretty good, despite not hitting the spec-sheet highs. Given good light the Samsung Galaxy S III Mini will give you passable shots, ideal for sharing. Focusing is a little on the slow side, however, more so in low light where shots show plenty of noise.

The final word goes to the battery. This is where smaller devices outpace their larger brethren. The Samsung Galaxy S III Mini may only have a 1500mAh capacity battery in it, but it performs very well. We found it would last through an average day without any problem and on some light days we found ourselves with 60 per cent battery left at the end of the day.

Of course, battery performance depends on what you do with your phone and as you hit data, play games, use the camera and listen to music, you"ll find the battery life drops off faster, but if you"re looking for a phone that will see you through the day, then the Samsung Galaxy S III Mini may well be it.

The Samsung Galaxy S III Mini looks good and doesn"t explicitly lack power, but the performance seems surprisingly sluggish when carrying out basic tasks. It does give you good battery life however.

It doesn"t hurt that this baby S3 has a pleasing design, a modern Android 4.2.2 OS, and a reliable camera. On the other hand, the smartphone is slower than most, and although the Mini debuted as a midrange Galaxy S3 alternative, its hardware specs are entry-level by today"s standards. Although its credentials trail behind, the S3 Mini is pretty great for what is essentially a free phone, and an ideal 99-cent investment for smartphone first-timers.

Although new to AT&T, the S3 Mini in fact kicked off the trend of manufacturers issuing a slightly smaller, more scaled-back alternative to the premier smartphone that nevertheless kept the phone"s basic look, feel, and design elements.

With its October 2012 debut, the Galaxy S3 Mini became the cheaper, midrange alternative to the high-end Galaxy S3, while still remaining part of the S3 family. AT&T"s decision to include it in its lineup, despite the

Beyond its petite 4-inch screen size and slightly thicker chassis, the S3 Mini looks almost identical to the original Galaxy S3, with all the side swoosh accents, body shape, and button shapes intact. As with the original, this "mini me" comes in ultra glossy pebble blue and white finishes.

With its more compact feel, the Mini, which measures 4.8 inches by 2.5 inches by 0.39 inch and weighs 4 ounces, is small enough to slide into most pockets, but weighty enough so that it doesn"t get lost. That high-shine exterior is extremely reflective and smudge-prone, but it does feel pretty comfortable in the hand.

Let"s talk about the phone"s 4-inch Super AMOLED WVGA resolution display (800x480 pixels). At 233 pixels per inch, the Mini is far less pixel-dense than, say, the $100 HTC One Mini"s 340ppi-yielding 720p HD screen. But don"t let that worry you too much; the Mini"s resolution is still within range for its size and delivers the rich colors that AMOLED displays are known for. A bigger downside is that it also happens to be highly reflective, which makes words and images all but disappear in direct sunlight, even with the screen brightness cranked up to its maximum value.

Thankfully, when it comes to its OS, the S3 Mini has not been wounded by the passage of time. A year after it debuted globally with Android 4.1, AT&T and Samsung have wisely elevated the OS to version 2.2. Considering that we"re just now starting to see phones and tablets ship with Android 4.3, you can"t really ask for a $1 smartphone that"s more up to date -- or even a $100 smartphone, for that matter.

Whichever interface you choose (and yes, you can switch back and forth to your heart"s content), you"ll get some helper tools, like word tracing on the virtual keyboard. This helps keep larger fingers from getting too frustrated with mistypes on the S3 Mini"s more cramped screen. I personally go back and forth between pecking out letters and tracing them, and there are third-party apps that can also adapt to your style over time, even premeditating your next word choice.

Consistency is key, and that"s something that Samsung has mastered across its camera experiences on its gazillions iterations of smartphones. The 5-megapixel camera you get here in the S3 Mini is solid and reliable, producing roughly the same clear, colorful, well-defined images we"ve seen on so many other Samsung phones.

Back to the good news, the Mini"s 720p HD video is equally consistent with photo quality. Videos taken in ample light looks best, and the phone is capable of capturing pretty smooth video that adjusts as you pan. Audio pickup was fair, but, predictably, works best when the subject is closest and isn"t competing with ambient raucous.

I tested the Samsung Galaxy S3 Mini in San Francisco using AT&T"s GSM network (850/900/1800/1900MHz bands). Call quality hit right in the middle. While long calls weren"t pleasant, shorter discussions worked just fine, and the disruptions were never bad enough to impede actual conversation. I found that I constantly fiddled with the controls in an effort to nail down a comfortable audio level.

Performance hits expectations for this entry-level device, delivering highs and lows across the board. Navigation was swift enough when swiping through the S3 Mini, but it did take apps longer to load, and the camera app was especially pokey from shot to shot.

The Mini"s 1.5GHz dual-core Qualcomm MSM8930 processor could handle casual games no problem, but expect broken pixels for resource- and graphics-heavy games, like our common testing title Riptide GP2.

Battery life is always a tricky subject, because your actual drain depends on how you use the phone. AT&T"s Mini got a bump in battery capacity from the global version"s 1,500mAh juice box up to 2,000mAh, a nod to the phone"s LTE-driven consumption. This gives it a rated talk time of up to 11 hours and up to 15.4 days standby time. During our battery drain test for video playback, the device lasted 14.1 hours.

A few final specs to through your way: the S3 Mini has 8GB total internal storage, and can support an up-to-64GB microSD sidekick. It has 1GB RAM. FCC tests measured a digital SAR of 0.71 watt per kilogram.

Price is typically the most compelling feature in a budget device, making potential customers more willing to accept mediocrity for the sake of the bottom line. Not so with the S3 Mini. Though it was never high-end, even in its prime (and was never meant to be), it still packages together enough hardware and software features to provide an all-around complete software experience for first-time smartphone owners. I"m thinking especially of teenagers getting a first taste of responsibility and freedom, or really, anyone transitioning from a simple phone to a smartphone.

The 99-cent on-contract price does pump up the Mini"s value, and its modern Android version gives it an edge over AT&T"s other dollar bargains, like the (also good)

There are actually plenty alternatives to using the Power button on your Samsung Galaxy S3. You could let gravity do the work for you, or you can create an invisible "screen off" shortcut, which can be hidden anywhere on your home screen.

On paper the S3, launched in May this year, comes with identical imaging specification as its predecessor but offers some interesting new camera features such as a burst shooting mode, simultaneous HD video and image recording, a reduced shutter lag and a Best Shot function that recommends the best picture based on colors, lighting and sharpness.

Please note: We tested the US version of this phone which at the time of review was running Android V4.04 ‘Ice Cream Sandwich’. Samsung is currently rolling out Android 4.1 "Jelly Bean" for the international and US versions of the S3. Once this update is available we will have a closer look and update this review if it offers any new camera functions or changed image quality.

The Galaxy S3 slightly deviates from the standard Android hardware specification in so far that the navigation buttons at the bottom of the screen are hard-buttons rather than soft-buttons as it has been Android standard since the introduction of version 4.0 "Ice Cream Sandwich".

Like most latest-generation smartphones these days the Galaxy S3 has very few external controls. The power button is on the right, the volume rocker is on the left and on the front you"ll find the Home button. The other Android buttons, the Back and Multitask buttons, are implemented as capacitive touch-buttons left and right to the Home button. They light up as you touch them.

The Samsung"s excellent 4.8 inch screen is great for framing photographs but it inevitably makes the Galaxy S3 one of the largest smartphones around. And while the thin tapered edges look quite elegant in combination with the S III"s size they make the phone a little more "slippery" to hold as a camera than some of its rivals. If you use your Galaxy S3 a lot for taking pictures we would recommend the use of a case. It does not only protect your device but also makes it more comfortable to hold when taking pictures.

The Galaxy S3"s flash settings are very simple. You can turn it on, switch it off or set it to Auto mode and let the camera decide if it wants to use the flash. In video mode the flash LED can be used as a permanent video light. On the S3 camera app the LED does not provide any anti red-eye or focus light functionality but it can be useful for non-photographic purposes. There is a variety of apps out there that let you use it as a flash light.

There are four customizable short-cut buttons on the Galaxy S3"s lock screen, one of them takes you directly to the camera app. Simply tap the icon and swipe anywhere on the screen.

Apart from the flash options the Galaxy S3 offers a range of shooting modes which cater for different shooting situations. There is an HDR mode which combines three exposures automatically in-camera in order to increase the dynamic range of the photograph. Other modes incluse a burst mode, of roughly 6fps, a panorama mode and a smile shot mode that takes a picture automatically when your subject smiles.

DisplayPort version 1.2 was introduced on 7 January 2010.Gbit/s in High Bit Rate 2 (HBR2) mode, which allows increased resolutions, higher refresh rates, and greater color depth, such as 3840 × 2160 at 60Hz 10bpc RGB. Other improvements include multiple independent video streams (daisy-chain connection with multiple monitors) called Multi-Stream Transport, facilities for stereoscopic 3D, increased AUX channel bandwidth (from 1Mbit/s to 720Mbit/s), more color spaces including xvYCC, scRGB, and Adobe RGB 1998, and Global Time Code (GTC) for sub 1μs audio/video synchronisation. Also Apple Inc."s Mini DisplayPort connector, which is much smaller and designed for laptop computers and other small devices, is compatible with the new standard.

DisplayPort version 1.2a was released in January 2013Adaptive Sync.AMD"s CES 2014 on a Toshiba Satellite laptop by making use of the Panel-Self-Refresh (PSR) feature from the Embedded DisplayPort standard,

The DisplayPort standard does not specify any maximum length for cables, though the DisplayPort 1.2 standard does set a minimum requirement that all cables up to 2 meters in length must support HBR2 speeds (21.6Gbit/s), and all cables of any length must support RBR speeds (6.48Gbit/s).: §5.7.1, §4.1 Cables longer than 2 meters may or may not support HBR/HBR2 speeds, and cables of any length may or may not support HBR3 speeds or above.

DisplayPort cables and ports may have either a "full-size" connector or a "mini" connector. These connectors differ only in physical shape—the capabilities of DisplayPort are the same regardless of which connector is used. Using a Mini DisplayPort connector does not affect performance or feature support of the connection.

The standard DisplayPort connector (now referred to as a "full-size" connector to distinguish it from the mini connector): §4.1.1 was the sole connector type introduced in DisplayPort1.0. It is a 20-pin single-orientation connector with a friction lock and an optional mechanical latch. The standard DisplayPort receptacle has dimensions of 16.10mm (width) × 4.76mm (height) × 8.88mm (depth).: §4.2.1.7, p201

The Mini DisplayPort connector was developed by Apple for use in their computer products. It was first announced in October 2008 for use in the new MacBooks and Cinema Display. In 2009, VESA adopted it as an official standard, and in 2010 the specification was merged into the main DisplayPort standard with the release of DisplayPort1.2. Apple freely licenses the specification to VESA.

The Mini DisplayPort (mDP) connector is a 20-pin single-orientation connector with a friction lock. Unlike the full-size connector, it does not have an option for a mechanical latch. The mDP receptacle has dimensions of 7.50mm (width) × 4.60mm (height) × 4.99mm (depth).: §2.1.3.6, pp27–31 The mDP pin assignments are the same as the full-size DisplayPort connector.: §2.1.3

Pin 20 on the DisplayPort connector, called DP_PWR, provides 3.3V (±10%) DC power at up to 500mA (minimum power delivery of 1.5W).: §3.2 This power is available from all DisplayPort receptacles, on both source and display devices. DP_PWR is intended to provide power for adapters, amplified cables, and similar devices, so that a separate power cable is not necessary.

Display manufacturers may also use non-standard blanking intervals rather than CVT-RB v2 to achieve even higher frequencies when bandwidth is a constraint. The refresh frequencies in the below table do not represent the absolute maximum limit of each interface, but rather an estimate based on a modern standardized timing formula. The minimum blanking intervals (and therefore the exact maximum frequency that can be achieved) will depend on the display and how many secondary data packets it requires, and therefore will differ from model to model.

Mini DisplayPort (mDP) is a standard announced by Apple in the fourth quarter of 2008. Shortly after announcing Mini DisplayPort, Apple announced that it would license the connector technology with no fee. The following year, in early 2009, VESA announced that Mini DisplayPort would be included in the upcoming DisplayPort 1.2 specification.

On 24 February 2011, Apple and Intel announced Thunderbolt, a successor to Mini DisplayPort which adds support for PCI Express data connections while maintaining backwards compatibility with Mini DisplayPort based peripherals.

Micro DisplayPort would have targeted systems that need ultra-compact connectors, such as phones, tablets and ultra-portable notebook computers. This standard would have been physically smaller than the currently available Mini DisplayPort connectors. The standard was expected to be released by Q2 2014.

Direct Drive Monitor (DDM) 1.0 standard was approved in December 2008. It allows for controller-less monitors where the display panel is directly driven by the DisplayPort signal, although the available resolutions and color depth are limited to two-lane operation.

DSC compression works on a horizontal line of pixels encoded using groups of three consecutive pixels for native 4:4:4 and simple 4:2:2 formats, or six pixels (three compressed containers) for native 4:2:2 and 4:2:0 formats. If RGB encoding is used, it is first converted to reversible YCGCO. Simple conversion from 4:2:2 to 4:4:4 can add missing chroma samples by interpolating neighboring pixels. Each luma component is coded separately using three independent substreams (four substreams in native 4:2:2 mode). Prediction step is performed using one of the three modes: modified median adaptive coding (MMAP) algorithm similar to the one used by JPEG-LS, block prediction (optional for decoders due to high computational complexity, negotiated at DSC handshake), and midpoint prediction. Bit rate control algorithm tracks color flatness and buffer fullness to adjust the quantization bit depth for a pixel group in a way that minimizes compression artifacts while staying within the bitrate limits. Repeating recent pixels can be stored in 32-entry Indexed Color History (ICH) buffer, which can be referenced directly by each group in a slice; this improves compression quality of computer-generated images. Alternatively, prediction residuals are computed and encoded with entropy coding algorithm based on delta size unit-variable length coding (DSU-VLC). Encoded pixel groups are then combined into slices of various height and width; common combinations include 100% or 25% picture width, and 8-, 32-, or 108-line height.

Embedded DisplayPort (eDP) is a display panel interface standard for portable and embedded devices. It defines the signaling interface between graphics cards and integrated displays. The various revisions of eDP are based on existing DisplayPort standards. However, version numbers between the two standards are not interchangeable. For instance, eDP version 1.4 is based on DisplayPort 1.2, while eDP version 1.4a is based on DisplayPort 1.3. In practice, embedded DisplayPort has displaced LVDS as the predominant panel interface in modern laptops and modern smartphones.

eDP 1.0 was adopted in December 2008.Hz sequential color monitors, and a new display panel control protocol that works through the AUX channel.framebuffer memory in the display panel controller.Version 1.5 was published in October 2021; adds new features and protocols, including enhanced support for Adaptive-Sync, that provide additional power savings and improved gaming and media playback performance.

Internal DisplayPort (iDP) 1.0 was approved in April 2010. The iDP standard defines an internal link between a digital TV system on a chip controller and the display panel"s timing controller. It aims to replace currently used internal FPD-Link lanes with a DisplayPort connection.GHz clock and is nominally rated at 3.24Gbit/s per lane, with up to sixteen lanes in a bank, resulting in a six-fold decrease in wiring requirements over FPD-Link for a 1080p24 signal; other data rates are also possible. iDP was built with simplicity in mind so doesn"t have an AUX channel, content protection, or multiple streams; it does however have frame sequential and line interleaved stereo 3D.

On 22 September 2014, VESA published the DisplayPort Alternate Mode on USB Type-C Connector Standard, a specification on how to send DisplayPort signals over the newly released USB-C connector. One, two or all four of the differential pairs that USB uses for the SuperSpeed bus can be configured dynamically to be used for DisplayPort lanes. In the first two cases, the connector still can carry a full SuperSpeed signal; in the latter case, at least a non-SuperSpeed signal is available. The DisplayPort AUX channel is also supported over the two sideband signals over the same connection; furthermore, USB Power Delivery according to the newly expanded USB-PD 2.0 specification is possible at the same time. This makes the Type-C connector a strict superset of the use-cases envisioned for DockPort, SlimPort, Mini and Micro DisplayPort.

Later the same year, Apple introduced several products featuring a Mini DisplayPort.Radeon HD 5000 Series of graphics cards, which featured the Mini DisplayPort on the Eyefinity versions in the series.
