Its been more than 3 years, I am using the Galaxy S2.It was a great buy by me, never felt any problems until now because now the battery backup become empty within 10-11 hours of use.The colourful AMOLED display is awesome.
I never used a screenguard, bu even after rough use there is only a single minor scratch on screen, Thanks to the Gorilla glass.Almost all the games works well on this phone like high graphics Fifa 12, Real Racing, etc.Overall its a great phone.
