Samsung Galaxy S II (AT&T)

Verge Review

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. Samsung’s original Galaxy S was one of AT&T’s best smartphones, and managed to attract a lot of buyers — and now the Galaxy S II...

    I really love this phone.

    I used to have an iPhone 4 and loved it, but always had to wear this huge, bulky case to protect the glass from shattering. It felt like a freaking vase.

    This phone is sturdy, and I really like how I feel safe with it, especially with the plastic lip slightly above the screen.

    Yes, the screen is bright, saturated, and vibrant; that comes at a cost. First of all, this thing has REALLY low pixel density. Around 254 ppi. It also is constantly brighter than I want it to be, leading to some really painful moments in the mornings when I look at the screen. It also drains battery like nobody's business. A full battery at moderate usage and lowest brightness gets me through only about nine hours. My iPhone would be able to last about two or three days under those conditions.

    I'm not exchanging this phone for anything short of extraordinary. It's fast, vibrant, and I love android, but a short battery life and that terrible pixel density make me reluctant to recommend it to anyone but die hard techies under the age of 30.

    The Galaxy S II (i777) remains the best phone on AT&T. It's super thin, light and feels great in the hand.

    The screen is phenominal, the perfect size and beautiful. The battery life is amazing compared to the Captivate I used to have. The GPS is rock solid, the software is buttery smooth, and impossible to lag down. I have yet to find a way to make this phone not instantly snappy and responsive. With having Android on board, and a huge following the community support on this phone is great. While I don't like having to rely on community support, it's actually a big reason why I want this phone. It's a huge part of why I didn't get a Skyrocket and returned my Thrill.

    The Samsung Galaxy S II has been my first Android device I have owned coming from the iPhone 4 and previously owning an iPhone 3GS. The phones build quality is its weakest feature. The phone is extremely thin, but it feels too light and "plastic-y". The screen is phenomenal. The color and contrast are astounding. It is blazing fast with the 1.2 GHz processor and 1GB of RAM. I truly believe the camera is just as good or even better than the iPhone 4S. It produces amazing photos and videos-- A worthy replacement of a point and shoot. TouchWiz isn't as bad as the other skins that manufacturers put out, but you can always root the device and get a OEM or custom ROM to your liking. Battery life has been fantastic. I would go as far as saying that it's the same battery life that I had with my iPhone 4. Overall, I would still say it is one of the best Android phones on the market for AT&T.

    It's a great phone, no doubt. It looks and feels nice, even though the completely plastic casing feels mediocre. The screen is bright and insanely gorgeous, but colors are often a bit too saturated in pictures and web browsing, and the resolution is disappointing. The camera is great outdoors, but when there isn't as much light there's a ton of noise and soft edges. I've been getting better reception than my Atrix, but there are still times when AT&T's network just drags with 3-5 bars. It's very fast, and still is after a fair amount of apps are installed. Touchwiz actually improves on Gingerbread, I would say, as long as you use a different launcher. Battery life is pretty good, it's at least better than my previous Atrix. Android has tons of apps, but a lot of them are complete crap. Everything that I have not mentioned is pretty much great.

    BUT, AT&T decided to launch the Skyrocket about 3 weeks later for a lower price and stop carrying this one, so go look at that instead.

    Samsung sent me the Galaxy S II to review and when I had it I really liked it. First of all the design is just amazing on the camera, it's extremely thin and very light. And even though the 4.3-inch display is pretty large it felt better in the pocket than a smaller 3-inch smartphone which was a bit thicker.

    Samsung packs a whole lot into the thin body on the Galaxy S II. From the outside you can see things like the 4.3-inch Super AMOLED Plus display which is low resolution but extremely high quality. I didn't mind the low resolution probably because my eyes aren't the best but it also seemed to make reading eBooks easier on my eyes since I didn't have to have the phone as close to my eyes. You can also find dual cameras one is an 8MP camera but neither really take amazing pictures. But the cameras do get the job done and I guess that's alright.

    Inside you find a really fast processor which powers the smartphone along with 1GB of RAM and 16GB of storage. From my experiences with the phone I didn't have to use any task management apps at all. I could just run the phone and it would run smoothly no matter how many applications were open in the background. No apps had any real problem running, they loaded up fast, and I could switch apps fast. So performance isn't an issue here. And even though the smartphone has really good internals I was still able to get a day on a single charge of the battery which is ideal.

    As far as the software goes I wasn't too impressed. It runs TouchWiz on top of Android 2.3 Gingerbread. TouchWiz is one of the better skins on Android in my opinion but it still isn't great. I prefer the stock Android user interface. But even Android 2.3 Gingerbread's stock interface is kind of outdated when compared to Android 4.0 Ice Cream Sandwich which right now the Galaxy S II doesn't have. But Samsung has promised an update to ICS in Q1 2012 so stay tuned.
