My phone will not grid lock all of a sudden. It had frozen up the other night so i took the battery out and turned it back on and the lock wasnt there. Ive gone in to my settings and set up a new pattern but it will still not appear when i hit the power button. The same time this happened my sift 'home" key stopped working as did the "search" key. its annoying cause I have to hit the back buttton a million times to get home. i found someone else on this website with the same exact problem but no one gave her any solutions. I was thinking about doing a factory reset but I go through straight talk and Im nervous I will lose my minutes for the month and my phone number. Does anyone know what I should do to get the buttons working again??? HELPPP!!!!
