*NOT RESPONSIBLE FOR DAMAGES* I was so happy with my Galaxy S2... I was watching a video stream (not a flash stream) through the ICS 4.0.3 Video Player... I decided to improve my brightness level... normal when you go to the preferences and try to change something the video gets paused... for some reason the stream continued on the background... when I changed the brightness twice the player crashed and the screen went blank!!! I was like *SHIT*... Removed and reinserted the battery.... but when I went to the Video Player it again kept blanking the screen phone crashed... I couldn't watch a local file now!.... I was so upset!!! Felt like crying.... I was like shit, now I have to reset the whole phone... Then I got the flash of genius... Again I removed and reinserted the battery and booted the phone. I went to the Settings -> Applications -> All Tab (Top of page) -> Videos (App at Bottom area of list) and Clicked "Clear Data".... and Viola! Video Player works fine A big bug that Andriod/Samsung needs to fix!
