My phone keeps freezing and rebooting. When it isn't doing that I get error messages all the time. Homescreen stopped working, would you like to stop. Android has stopped working, would you like to stop. Maps just pops up out of nowhere that is has quit working. I have cleared the cache and I eventually did a factory reset and did not reinstall 99% of apps I had. Nothing works. I can't even answer the phone when someone calls because it takes so long for the swipe to be accepted it goes to voicemail. Any suggestions? I am not due for an upgrade until May.
