Samsung Galaxy S II Skyrocket review: Aiming for the stars

We have the Samsung Galaxy S II Skyrocket all set on the launch pad. Announced together with the HTC Vivid, the smartphone is among the first LTE enabled devices, compatible with AT&T's all new LTE network. The smartphone is certainly a welcome...

Quad-band GSM and dual-band 3G support ; 21 Mbps HSDPA and 5.76 HSUPA support ; LTE network connectivity ; 4.52" 16M-color Super AMOLED Plus capacitive touchscreen of WVGA (480 x 800 pixel) resolution ; Android OS v2.3.5 with TouchWiz 4 launcher ; 1.5...

No dedicated camera key ; No NFC support out of the box (a future update should address this issue) ; WVGA screen resolution is not on par with the rest of the competition in this class

With the addition of an LTE enabled Galaxy S II to the U.S., Samsung has literally a version for every possible taste out there. The Galaxy S II Skyrocket however, is clearly the best equipped for the future with its spanking new radio on board.

T-Mobile Galaxy S II

What else is there to say? Whether in its original, exotic exterior, its lightly changed but rather more accessible AT&T-flavored model, or the decidedly Epic Sprint version, the Samsung Galaxy S II has never failed to impress us. In fact, we called...

Clean, good-looking design ; Great performance, especially while surfing ; Excellent screen ; Solid camera

Offers shorter battery life than its siblings ; WVGA resolution

T-Mobile's Samsung Galaxy S II didn't fall far from the family tree. It's good looking, fast and an overall great phone.

Samsung Galaxy S II T-Mobile review: A dragon's heir

The T-Mobile version of Samsung Galaxy S II is has taken a sharp departure from its GSM siblings. Compared to the original I9100, the droid has grown in size considerably. Its face has changed as well, putting it in line with the U.S. lineup of Samsung...

Quad-band GSM and dual-band 3G support ; 42 Mbps HSDPA and 5.76 Mbps HSUPA support ; 4.52" 16M-color Super AMOLED Plus capacitive touchscreen of WVGA (480 x 800 pixel) resolution ; Android OS v2.3.5 with TouchWiz 4 launcher ; 1.5 GHz Scorpion dual-core...

No dedicated camera key ; Slim body has poor grip when taking pictures ; No FM radio

The Samsung Galaxy S II for T-Mobile is priced at $229.99 after a $50 mail-in-rebate. Of course, you will also need a two-year contract with the magenta colored wireless provider in order to qualify for the above price.

Samsung Galaxy S II for AT&T review: A legend reborn

Today, we have the AT&T Samsung Galaxy S II at the start line. Out of the U.S. trio of power- droids, it comes closest to the original, having kept its slim line and measurements, while changing its face in a subtle fashion.

Quad-band GSM and quad-band 3G support ; 21 Mbps HSDPA and 5.76 Mbps HSUPA support ; 4.3" 16M-color Super AMOLED Plus capacitive touchscreen of WVGA (480 x 800 pixel) resolution ; Android OS v2.3.4 with TouchWiz 4 launcher ; 1.2 GHz dual-core Cortex-A9...

All-plastic body ; No dedicated camera key ; Super slim body has poor grip when taking pictures ; Non-hot-swappable microSD card

When the original Samsung Galaxy S II entered the scene five months ago, it blew its entire Android competition out of the water. The race wasn’t even close – the droid was not in a mood to take any prisoners.

If you don't already know all about the Samsung Galaxy S II, where have you been the past two months? The successor to one of the most popular Android

Class-leading speed and responsiveness ; Awesome Super AMOLED Plus display ; Great still camera, capable of 1080p video

Build quality could be better ; Pixel density is behind the leading pack ; Browser rendering suffers from aliasing

Samsung I9100 Galaxy S II preview: Second encounter

Having earned its place in the Android hall of fame, the original Galaxy S can start thinking about retirement. And these won't be thoughts of fear and worry. With a replacement on its way, the veteran can look forward to getting the respects it deserves.
