http://androidforums.com – My phone dropped in a i sick for maybe one second, it was fine for an hour then the screen went all discoloured, i set it in rice and it was back to normall in 15 minutes... 3 hours later the screen is flashing on and off and is completely tinted green. I have NO idea what to do, its been in rice all night and it still doesnt work properly. Any ideas? I just got this phone less than a month ago too... (General)
