Conclusion: This part of the review is easy: The Samsung Galaxy S II is the best Android smartphone available on the market today. If you can ignore a few tiny niggles like missing NFC support and some Samsung bloatware, it's darn near perfect otherwise.
Pros: Good design, Brilliant display, Very fast processor, Solid 8mp camera with 1080p video recording, Good battery life, Improved user interface
Conclusion: Unequivocally, the Samsung Galaxy S II is one of the best Google Android smartphones on the market today. It’s incredibly thin, the Super AMOLED Plus screen is simply breathtaking, and it has performance up the wazoo. The only thing that might hold you back is the TouchWiz UI, which isn’t everyone’s bag. That and you know that there is always something nicer in Android land just around the corner.
Summary: As with the Samsung Galaxy S II on AT&T, Sprint, and T-Mobile, there's a lot to like about U.S. Cellular's version. This $179 device has a gorgeous AMOLED display, speedy processor and a quality camera. However, its lack of 4G speeds makes us feel like we're forcing a race horse to give pony rides at the state fair. Those looking to take advantage of U.S.
Pros: Brilliant display, Can upgrade to a new phone in as little as 11 months, Strong performance, Fun built-in camera effects
Cons: Not 4G LTE compatible, Advertising offers appear as notifications, Below-average battery life
Summary: Samsung had unprecedented success last year delivering its Galaxy S line of flagship Android phones to a global stage, and for good reason: it launched as one of the thinnest smartphones in the world, the homegrown 1GHz Hummingbird processor was plenty fast for its day, and the 4-inch Super AMOLED display was a serious dazzler.
Pros: Blazingly fast, Thin and light, Gorgeous display
Cons: Low screen resolution compared to other high-end Android phones on the market, TouchWiz still less attractive than stock UI, Not a global phone (the Photon 4G is, for the same price)
Summary: The question every manufacturer of a non-Apple smartphone on AT&T has to answer is “why buy this over an iPhone?” For Samsung and most other Android handset makers, the answer is a big, bright screen, fast speeds, and all the Google integration you could want. Manufacturers are flooding the carrier with similar phones, hoping to catch buyers’ eyes with something.
Pros: Big, vibrant Super AMOLED Plus display, Super fast processor, Solid camera
Cons: Display resolution is too low, "4G" speeds are very slow, Body feels cheap and breakable
Summary: T-Mobile is now the only American carrier without the iPhone, and it's betting the farm on Android — a platform where Samsung's devices have typically been the cream of the crop. The $229.99 Galaxy S II (with a two-year contract, of course) is a natural upgrade to its top-notch, huge-selling predecessor — it’s got a bigger screen, and beefier internals — but is it enough of a step up?
Pros: Big, bright screen, Excellent cameras, Very fast
Cons: Low-resolution display, Terrible speakerphone, Lots of bloatware
Summary: The S II was a technological marvel when it first came out. That's closing in on a year ago now, but the phone is still one of the top phones out there. With a chipset that puts most phones – and tablets – to shame, enough RAM and ROM to not cause any of the typical low-end Android phone issues, a screen that is hard to hate, and a camera that you would actually use for proper photos it seems to have it all.
Excerpt: Samsung promises that the Galaxy S II is thinner, lighter, and faster than the Galaxy S. They were able to make that correct with the Galaxy S II. The Galaxy S III runs Android 2.3 with TouchWiz. This phone is similar to the Galaxy S but much more powerful. Read on for all of the juicy details. Hardware The Samsung Galaxy S II is 8.49mm thick. The measurement grows a little at the phone’s bottom. Even with the bulge it is still under 1cm.
