i just had my screen replaced and now the keypad will not show (the screen goes dark) when after I make a call or one comes thru. Needless to say I cannot access my voicemail, because I cant enter my passcode, and I cant on receiving some calls..press 1 for english..lol....does anyone know what would cause this? is it the replacement screen? or is it residual from when I dropped it in water awhile ago, but it had been fine till the screen replacement. I really dont want to put anymore money into this phone, i may as well get a new one..........
