Physical Impressions
The button arrangement on SGS2 continues the trend set by the international version of the original SGS, and eschews the search button, instead going with (left to right) menu, home, and back. Of course, regional variants are going to have different button arrangements, but this three-button approach seems to be a mainstay of the international market. When I hand the phone to most people, there’s usually a bit of confusion about what the home button does, and many mistake it for an optical or capacitive trackpad. Instead, the button is just that - a button. They’re backlit, and there are options to define backlighting behavior in the stock ROM - when in the dark, for a few seconds, and so forth.
Update: You can alternatively search by pressing and holding menu. Thanks everyone!
I have to be honest that continuing to shun the search button confuses me. Not just because not having it means we can’t run kwaak3 and get to console without lots of work, but because not having it made me realize how much I use it. Thankfully almost everywhere that I’d use the search button there’s a contextual shortcut - menu, then search. It’s just an added button press in the occasional spot, which can be alien if you’re used to having that button.
As I mentioned earlier, the battery cover is one piece of plastic which pries off and is held on with clips. It isn’t particularly sturdy, so thankfully getting the battery cover off isn’t a harrowing experience. Underneath is the SGS2’s large 6.11 Whr battery, microSD slot, and SIM slot. The microSD card can’t be accessed without a battery pull, and the card clicks in and clicks out. You can get the SIM out without a battery pull, however, and word has it you can even change SIMs without rebooting despite the prompts. At the very top is a ribbon antenna which is pretty evident, and below that is the camera module with adjacent LED flash.
There’s really not much to say about the phone with the battery cover off, everything is perfect here, and it’s clear just how much of the device’s internal volume is dedicated to the SGS2's relatively large 6.11 Whr battery.
Overall the SGS2’s in-hand feel is much better than its predecessor - it’s incredible how much a different back texture and 1.6mm of reduced waistline can make a phone feel. Where I waver back and forth is the weight department. The competition has largely gone in a design direction that employs metal and thus results in heavier devices. As a result, SGS2’s light weight seems to imply a certain level of cheapness where really there is none. I guess that’s the problem - even though SGS2 has metal internally for structure, the exterior is entirely plastic, and that’s what’s ultimately the material that sets user perception. The good thing is that though it feels light, SGS2 has solid build quality.
There are no rattles when the vibrator is going, no flimsy parts that might snap off or break (like the old microUSB door), and few places where dirt can encroach. There’s also very little flex. It’s impressively solid after you get over the hurdle that is its light weight.

Guys, that mysterious notch you write about is not for straps, it's for phone charms, and it's arguably my favourite feature of samsung phones. (In korea, phone charms can be used for more than just cute things, one can get a T-money card that will hang here, or an apartment key).Tishyn - Wednesday, September 14, 2011 - link
I spend hours every week just browsing through reviews and tests comparing devices and vendors. This is one if the most interesting and most comprehensive review I've read for a veery long time.I especially enjoyed the rendering part and how it relates to the ultra mobile device market. Thumbs up!

Brian / Anand, why are you so reluctant to test chips from this company? ZiiO tablets, sporting the ZMS-08, are available for a while now and i'm sure Creative would send you the new Jaguar3 tablet (ZMS-20) if you guys would ask for it.The ZMS-20 has 26 GFlops ... faster than anything you've tested till now. The ZMS-40 coming in Q4 doubles that number!
I'm an old school IT technician and I for one don't understand your lack of interest. The GPU's in these chips are based on technology that Creative acquired with the 3DLabs purchase.

Just a quick tip: You can take a screenshot by pressing the power and home button at the same time.If you double tap your home button it will bring the voice talk feature.
While watching video clips just press the power button to disable the touch sensitive buttons.
Swipe your finger to the left on contact name to send him a message
Swipe you finger to the right on the contact name to dial the contact.
To see all the tabs in the browser just pinch inside twice :)
If you experience random reboots when you drop it on the table, or if you are leaning towards things or running, then try to cut a piece of paper and put it under the battery. It happens because the battery shortly looses connection to the pins. If you check XDA you can see that many people has this problem, and I had it too. I was experiencing many random reboots whenever I had it in my pocket, but after I pit a piece of paper below the battery they all disappeared.
A few things...
- GPS is horrible if you ask me. Unless I download the data before with gps-status then it takes ages. Mostly 15-30 seconds with 2.3.3 (no idea if the radio got updated in the release)
- Kies AIR is HORRIBLE! It's on pair with realmedia's real player from 10 years ago. Crash on crash on crash and sluggish behavior.
- I don't know whether it's the phone or not, but I've been missing a lot of text messages after I got my Galaxy S2. I'm on the same net, but along with the poor GPS reception I'm suspectiong the phone :(
- There is a stupid 458 character limit on textmessages, and then they are auto-converted to an MMS message. There is a fixed mms.apk on XDA (requires root) or you can download something like Go SMS Pro (still free) on the market, which removes this stupid limit.

OddI haven't seen any posts about the battery disconnect issues and if you've been browsing the xda forum, probably saw my thread about dropping my phone on concrete twice...
As for Kies AIR, i've used it twice and my expectation was low to begin and it wasn't that bad. Some things were definitely slow but it's a good start
-GPS for me has always been solid. I even used it on multiple trips in less than ideal location, not a single glitch even with shoddy cell reception.

I've been using Sprint's SGS2 (Epic 4G) for less than a day, but already there are some annoying points which I'm surprised aren't mentioned in this review:1) The digitizer lags behind finger movement.
In the web browser, when your finger moves, there is a disconnected rubber-band effect before the screen catches up with your finger. This is visible in the browsing smoothness video as well, and it's very noticeable in actual use. Coming from an iPhone 4, it feels cheap and broken.
2) Back/Forward navigation often ignores the previous scroll point.
If you spend some amount of time reading a page you arrived at from a link (it seems to be about 10 seconds or so), hitting back doesn't take you back where you were previously reading from -- instead of returning you to the page position where the link was, it drops you at the top of the page. This makes real web usage tedious. On the Sprint, the timing seems to be related to when the 4G icon indicates sleep mode: hit back before the radio sleeps and you are returned to the right spot. In actual use, this rarely happens.
3) The browser resets the view to the top, even after you've started scrolling.
When loading a page, there's a point in which the page is visible and usable, but it's technically still loading (which can go on for quite a awhile, depending on the page). It's natural to start reading the page and scrolling down, but typically the phone will randomly jerk the scroll back up to the top of the page, sometimes several times before the page is done. This is unbelievably annoying.
I suppose expecting an Apple level of polish prior to release is unrealistic, but Samsung seems hell-bent on positioning themselves as an Apple-level alternative; even the power brick looks like they took the square Apple USB charger, colored it black, and slapped their logo on it. The point being, they're inviting direct comparison, and it's a comparison their software team isn't ready to deliver on -- certainly not out of the box.

How are you supposed to use this phone if the keyboard is covering up the text fields, there's no "next" button to get to the next field, you can't see what you're typing, and there's no button to make the keyboard go away?Case in point: go to Google News and click on Feedback at the bottom of the page. There's no scrolling room at the bottom, so the keyboard obscures the fields; I was unable to send feedback to Google that their news site was opening every link in a new bowser window on a mobile phone (...) despite my account having the preference for that set to "off", because I couldn't navigate the form fields.

I love the green wallpaper on the first page of the review, but I can't find it anywhere. Could someone point me to where I could find it?
