Very good smartphone - in all disciplines

I own the Samsung Galaxy S2 for over a month - and in that time it has consistently convinced me:
- Very good display (brilliant and fast response time)
- Very fast (by dual-core technology, which both "everyday use" itself - eg Mult Ista King of different applications - as well as "extreme operating" - for example - 3D games - becomes noticeable)
- Very good camera (both video and photo) supported by a very good photo light!
- As usual, very good Android operating system (especially when users of different platforms is Google -> problem accounts synchronization)

From me there is an absolute buy recommendation. The only negative point (but does not affect my rating) is a bit suboptimal positioned "back" button comes on from time to time (for example, when browsing) by mistake you ...
But that does not affect really the impeccable operation of this all-around smartphones.
