Finally Samsung Galaxy S4 is launched with new revolution technology. S4 supports 2G -GSM 850 / 900 / 1800 / 1900, 3G-HSDPA 850 / 900 / 1900 / 2100, 4G –LTE in selected region. The phone is available in two colours – Black Mist and White Frost. The first thing that you notice when you pick up the phone is that it doesn’t feel bulky. This smartphone introduces revolutionary technologies like air-gestures and eye sensor.
The company doesn’t changes the design much as Samsung galaxy s3. In the body design HTC ONE is best choice. The dimensions are 136.6 x 69.8 x 7.9 mm (5.38 x 2.75 x 0.31 in). As it is known the slimmest and lightest phone in market with 7.9 mm (0.311 in) and weighing 130 g (4.95 oz). The front of the phone still features a physical Home button and two capacitive touch buttons for Menu and Back controls. The different sensors, front camera, notification light and earpiece grill sit above the screen.
Overall, the phone looks better than the Galaxy S III as it features a narrow body and thin bezel but doesn’t feel alluring when compared to the like of the iPhone 5 and HTC One due to the use of polycarbonate (read plastic) materials.
The phones has true hd resolution 1920 x 1080. It is achieved by designer to put this resolution in 4.99 inches with 441 ppi(pixels per inche) density. The phones uses gorilla glass 3 so you can scratch but it doesn’t matter. As compare to sony xperia z phone does not have water proof screen.

The secondary camera has 2 megapixels with dual video call. The back features the 13-megapixel camera, with the LED flash right below it. The back (of the Black coloured model) still has that pseudo matte finish on the glossy plastic surface that attracts fingerprints. The White coloured model doesn’t have the pseudo matte finish and instead sports a different dotted pattern which we found a little better.
