Samsung Galaxy S2 specs review

The Galaxy S2 is defined by Samsung and carriers with a two sentences: “ultra-powerful, ultra-thin, ultra brilliant” or “vidid, fast, slim”. It inherit the  powerful hardware and upgrade the specification makes Galaxy S a Android benchmark. Let have a look at performance of 4.3 inch AMOLED screen, 1.2GHz dual core Exynos processor and 1GB RAM.

Full Hardware specifications

Galaxy S II uses a Super AMOLED Plus screen. However, the revolution remains WVGA (800 x 480) which makes some users disappointed as there have some qHD (960 x 540) Android smartphone entered the market.

Galaxy S2 uses a 2 megapixel camera on the front. But it don’t support GTalk video chat now. The main camera is 8 megapixels which can record 1080p HD video with the great support from 1.2 GHz dual core Exynos processor.

Galaxy S2 is very thin but have a 1650mAh battery.

On the top, there is a 3.5mm handset port and a noise reduction microphone which offer quite good voice quality during calling. The Micro USB port, uses for charging or data transferring, is placed on the bottom side.

The power button is placed on the right side. It should be a good idea as the Galaxy S2 is very big.

The back shell is just a thin plastic. SIM card slot and Micro SD card slot are both covered by this shell.


Galaxy S II carries TouchWiz 4.0, which is similar to HTC Sense or Moto Blur. You can change to LauncherPro if you don’t like the default UI.

TouchWiz 4.0 improved the effect when changing interface. It includes 7 pages. Samsung developed beautiful Widget tools.

Battery Life

The dual core processor don’t consume two much battery power as believed. With moderate usage,  I have seen this phone hold for 2.5 days. But if you run many apps or playing games on it, it’s more likely that I will need to recharge it every other day. Or you can low down the brightness of the screen to extend 30%-40% battery life.

However, it very great of the battery life. And some Power Control Android widget may makes it better.
