can someone PLEASE help me before i throw my phone against a wall i had my orange san Francisco for a few months now, its work perfectly fine up until recently. now when i am texting, using internet, facebook or just navigating through my phone the touch screen becomes very slow, as in, i can touch an icon to select it and it can take 4-5 seconds to select, not a long time in realitly but when trying to text someone its almost impossible!! this can happen on every letter i want to select. i have kept upto date with any updates that come through automatically including android facebook. just recently i have had 2 updates for it in about 1 week. im not sure if these updates have anything to do with it but it has seemed to have got worse since then. also i have cleard cache, history and cookies, switched it off, taken battery and sim and sd card out too but still the same anyone PLEASE have any ideas????
