Product Description

The follow-up to the extremely successful GALAXY S, Samsung's GALAXY S II is a powerhouse of a smartphone in a fantastically sleek and lightweight design. Considerably thinner than the original GALAXY S and rivals such as the iPhone 4 (8.49mm v 9.3mm) the GALAXY S II is stunningly light (only 117g) and packs the latest version of Android (Gingerbread). The one feature most people will notice immediately is Samsung's best ever screen; the monster 4.27-inch Super AMOLED Plus screen runs at 480 x 800 resolution, has colours visibly brighter and more vivid than other phones, better contrast and lower power consumption, and performs superbly for gaming and watching video. Plus there's an 8.1 megapixel camera with full 1080p HD video recording, video playback at 30 frames per second and a dual-core processor, with each core running at a blistering 1Ghz for an incredibly responsive experience. The GALAXY S II comes with four hubs to help you make the most of your Galaxy S II; Social, your chatting life in one place, Readers, Samsung's new ebook reader area, Game, the easiest way to download and play the best games, and Music, with access to over 12 million tracks.

Good things:

- Awesome screen - all the greatness of OLED (perfect blacks, high contrast, looks good in direct sunlight) without the ugliness that was PenTile. Here you just get the bright, popping colors. Oh, and at 4.3", it's a pleasure to look at from any distance. The resolution is still 800x480, though. Wish they'd up it to match iPhone.

- Very light. I mean, VERY light. Samsung wasn't kidding when they stressed that point. Considering the size of this thing, it's very hard to believe. When you put the phone into someone else's hand for the first time, they usually are confused because they expect it to feel more "solid", and not so featherweight.

- Fairly thin. Good if you wear your phone in the pocket of your pants.

- The UI is buttery smooth, with no hiccups that are common on all other Android phones I've seen. Not sure if it's Samsung's new powerful GPU (Exynos), software optimizations that they did, or a combination of both, but overall this thing is just as slick as iPhone 4.

- It can be rooted, and custom ROMs already exist. No signed bootloaders or other similar malarkey.

- It comes with Android 2.3. That means better perf, WiFi tethering/hotspot out of the box, and the ability to tilt and rotate the map in Google Maps - among other things.

- It comes with Polaris Office. It is a very nice Android office suite - from what I've seen so far, more full-featured than Docs to Go, QuickOffice etc - especially when it comes to supporting advanced MS Office features such as charts. It cannot be purchased from the market, and only comes bundled with select devices, such as this one or Asus Transformer.

- MicroSD card slot, for all those gigabytes of music.

- It has CyanogenMod.

This phone is awesome. As far as appearance goes, it's *thin.* Like, 8.49 mm thin. Much thinner than the iPhone 3G that I owned previously. Although it's thin, the curved sides allow for easy gripping. The casing itself is plastic, so it feels cheaper than other all-aluminum phones, but its absolute thinness prevents if from feeling cheap. It's a classy phone.

The screen is massive (4.3") and beautiful. It's probably the best single feature of the Galaxy S II. You can view the display from all kinds of angles (good for sharing pictures of cats) and the colors really pop. This is all due to Samsung's patented Super AMOLED Plus technology. It's the secret juice that makes the Galaxy S II's screen really stand out when compared to other phones. One semi-downside of the display is that it's resolution is 800x480 and NOT qHD. This means when watching HD movies you have to deal with annoying black bars around the film to maintain the viewing format.

The awesomeness of the screen, though, really can't be overstated. It's vibrant. Pictures and video are vivid and really pop off the screen, even in direct sunlight. The viewing angles and contrast are great. Really, a superb screen. Blows my old iPhone 3G's screen out of the water. It's a beauty to behold. Web pages render stunningly.

Samsung's S-AMOLED Plus technology also helps with battery life by selectively powering down black pixels to maintain battery life. This means that even though the phone has an impressive two cores clocked at 1.2GHz each and that beautiful 4.3" display, battery life is still impressive. I manage to go two days between charges and that's with fairly frequent usage.

First off, if money is hurting you, then look for another phone. But if you can afford to shell out $700, then the SGS2 unlocked is perhaps the only phone that can justify it.
**Camera---best i've seen on a smartphone (barely beating iphone 4)...

**Screen---vibrant colors on the samoled+ w/o the pixelated effects on the regular samoled. the 4.25 isn't too big or too small for my taste. although i must add that it looks bigger in real life than it does in the video reviews.

**Form factor---Very slim, incredibly lightweight, takes a little getting used to bc the size-thickness ratio. almost feels like holding some type of card...really wish they would have used a smooth battery cover instead of textured.

**Build quality---despite the fact the its form and plastics make it seem cheap, it actually feels pretty solid. the batter cover is made of some type of material that makes it very flexible w/o snapping.

**Dual core cpu---smooth. but what can I say for 1.2Ghz dual core? other than that, you wouldn't really notice much else difference from a 1Ghz single core...for now anyways.

**Media---Codecs that let you play DivX, Xvid, among others is great. Havent really tested games on here, so cant comment on that. DLNA is cool, but I miss the HDMI out.

**Battery---I've heard horror stories about the 1650mAh battery life, but I honestly havent seen any worse performance compared to other HTC/Samsung/Moto android smartphones. YMMV

**Software---GB 2.3.3 on there with touchwiz 4. TW4 is really starting to grow on me, but I wish it had more and better widgets like an rss news feed, or a friends feed that blends twitter and fb together. Although TW4 widgets look really pretty, some stuff like the keyboard needs more refinement.
