The European version of this smartphone is built around a quad-core 1.4 GHz Exynos 4 processor, which has proved to be faster than NVIDIA's Tegra 3 chip. The U.S. version, on the other hand, has a dual-core processor.
No matter where this device is released, it sports a 4.8-inch Super AMOLED screen with HD resolution, which is also superior to other HD displays, a huge battery with 2100 mAh, and the Android OS 4.0.4 operating system backed up by the TouchWiz user interface. The later is enriched with numerous options of gesture management.
Build & Design
No matter what you may have read about this phone based on early impressions, the Galaxy S III is far better in reality than in photos. Its large display is so dominating and distracting, even when turned off, that you simply aren't aware of what the back is made of. That said, the casing is made of a type of plastic material that is is exceptionally solid, incredibly resistant to scratches and damage, and particularly light. When holding it this handset in hand, you won't have the impression that it weighs 133 grams. Quite the opposite -- it seems lighter.
Its rounded casing edges also make the device's relatively large dimensions -- 137 x 71 x 8,6 mm -- seem smaller.
Display
One of the more impressive features of the Galaxy S III is its Super AMOLED screen with a 720 x 1280 pixel resolution. This offers a pixel density of 306 ppi on a 4.8-inch diagonal -- while is not the maximum we have witnessed on smartphones, the sharpness, color vividness, contrast, and the viewing angle definitely surpass almost all previous devices.
The touchscreen offers an equally pleasant and superior experience than we have seen on Apple's iPhone 4S. It should be kept in mind that Apple's device offers a 1.3-inches shorter diagonal, which leaves a far different impression in practice. Furthermore, the screen on the Galaxy S III is covered by Gorilla Glass 2, mildly convex along the edges, which makes it very pleasant to use, especially which moving the finger left to right across the screen.
Compared to the displays of other phones with a similar size, such as the HTC One X, the Galaxy S III offers a better experience. The best example that shows the differences is flipping through the home screen -- this takes place in a motion which offers a seemingly 3D look, making the sharp edges of widgets, icons and other elements on the screen not the least bit jaggy. This creates an impression that the screen actually has depth, i.e. a third dimension, which is not the case with any other phone. All these advantages can be seen in other situations as well, such as while playing games, viewing photographs, watching videos etc.
The contract on Samsung's Galaxy S III is very naturally set up, despite the fact that Samsung produces even more technically modern displays (Super AMOLED Plus), the usage matrix on this device is such that it enables good visibility, regardless of the viewing angle.
Still, a loss of contrast is noticed once the phone is directly exposed to sunlight -- this loss is not as bad as on some other devices with Android OS but is a bit greater than on the iPhone 4S. In this situation, the design of the Android and TouchWiz user interface is a shortcoming, not an advantage, as iOS and Windows Phone offer an exceptionally contrasting user interface that makes them easier to use in direct sunlight. This can be partially solved by choosing exceptionally dark wallpaper, at least for working with the desktop.
Other Design Elements
The power key on this smartphone is conveniently situated on the right edge of the phone, which means that snapping the phone from stand-by can be done with just one hand, without the need to move it a centimeter or two up and down, as the case was with its predecessor, the Galaxy S II.
Apart from the power button on the right edge, the Galaxy S III has a volume control switch on the left side and a recognizable physical key in the center of the device, just below the display -- this is used as the home key. Next to it are two capacitive keys for activating the menus on the left-hand side and the back key on the right. These are all the keys this device includes -- Samsung does not have a special key for camera activation and taking photographs on this phone either.
The bottom of the phone features a tiny microphone and a micro-USB slot which is also used for connecting the device with HDTV via MHL technology. The upper edge includes an additional microphone for video calls and a standard audio output port, while the back features an 8-mega pixel camera, a LED flash and a speaker.
The cover which overlays the entire back side hides a battery which can be taken out, a microSD memory card slot and microSIM card slot. Using the microSIM slot, Samsung joined HTC and Nokia which did the same with their top models, facilitating the migration of iPhone owners to these rival handsets.
