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.

When i am already using it for months and months now, and i am already thinking maybe next month or 2 i will replace it with its successor the Nexus Prime or what ever it may be called...Again here the complains about no updates.
What are you people complaining about, please...
Samsung releases, yes not officially but they are real samsung releases, quite often roms
for example here are the SGS2 once's:
http://www.samfirmware.com/WEBPROTECT-i9100.htm
A few releases per month, i am now on the latest one (2.3.4 of August 12)
If you look there to other phones you also will see many updates of all the latest phones of samsung.
So it is very easy and you dont need to root if you don't want to, just flash these roms. and you have a updated samsung made rom. (but yes 'leaked')

"Vellamo produces its scores directly from frame counters, so what you're looking at is a direct representation of how fast these devices scroll through the three web tests above. The Galaxy S II is 20 - 35% faster than the Photon 4G and 45 - 100% faster than the EVO 3D."You mixed up Photon 4G and EVO 3D, either in the table or the comment under it. The data shows the SGS2 20-35% faster than the EVO 3D and 45-100% faster than the Photon 4G.

I thought I was the only one noticing this too. I'm also concerned with the adreno missing from the 2.1 off screen render tests, as well as pointing out that it would definitely be beating the S2 in GL 2.0 Pro if resolutions were normalized there. Feels like the whole thing was meant to really set the mali on a high horse. Don't get me wrong, I think it's great, just not "double the speed of the competition" when you throw the entire lineup in the mix.poohbear - Tuesday, September 13, 2011 - link
Nice to read this review finally, it is indeed an awesome piece of hardware. Im not even sure the iphone 5 will be able to compete? guess we'll find out next month!PWRuser - Tuesday, September 13, 2011 - link
Is the SGS2 memory the newer 30nm LPDDR2 1066 or the 800 one found in older phones?QWIKSTRIKE - Tuesday, September 13, 2011 - link

Just for those who would like to know I am running The galaxy s2 overclocked to 1.6Ghz and its rock steady no crashes or freezes does not even get much warmerLinpack Single Threaded = 74 average and Multithreaded = 114
Revolution rom with ninphetamine 2.1.3 kernel

Just for comparision.. I have a HTC Sensation clocked at 1.6ghz with a Sense based rom. It's actually perfectly stable to 1.78ghz here but 1.6 should be no problem for any sensation.Linpack Single Threaded = 58 average and Multithreaded = 95
Pyramid3D 7.4.0 with faux123 0.1.4 kernel.
CM based roms just popping up, so anxious to see how a non-sense rom compares to the SGS2.

is not a coin cell battery. it is a supercapacitor, sort of a cross between a capacitor and a battery, they use them as a buffer between the phone and batterylchen66666 - Tuesday, September 13, 2011 - link
Rumors of iPhone5 indicate that iPhone5 will have the iPhone4 form. If this is realy, that would quite disappoint me. I will definitely consider GSS2 when I upgrade my old iPhone3GS. I was hoping iPhone5 comes with 4"+720P display+some other improvement(new camera chip, new design of antenna, and new CPU). 4" seems to be the sweet spot to be the smart phone(not too big, and not too small). If Apple doesn't have much improvement in the display. The faster CPU is not that useful.The review is very detail. Not very happy with a couple of things on GSS2. Resolution is not high enough for a 4.3" display. Audio quality is not good. Seems like GSS2 has very good camera chip for video and photo. Really like it. From your other review, I got impression that Super ALMOD plus display is much better than IPS. From this review, seems like SALMODE+ is similar to SIPS display used on other smart phones. I haven't seen Samsung SALMODE+ display in person.
