Hi! I've update my SGS2 from 2.3.3. to 2.3.4. via Kies just out of curiosity... I regret it now because my screen is not that crisp anymore... It seems more darker and in screen test mode (*#0*#) in dimming option the fade is very obvious(i can see the fading lines). I tried to search the net for a solution but no such luck so I'm asking here for help. Thanks in advance, have a nice day!
