for some reason my 3 month old 8310 has started locking up and the only way to get it back is a battery pull. usually when I check a message or go to reply to a message
I have 27,046,012 free memory
running apps: PTT (don't have PTT), call log, home screen, browser, messages
I mean I can't do anything, scroll ball doesn't work, can't make calls, menu button doesn't work, can't turn off the BB. It is frozen, locked up, inoperable, I can do nothing on it until I pull the battery
Sometimes a BB will freeze up like a computer does. All it takes is a battery pull to fix it. Very Normal. But you may have to many apps installed or too low of memory that will cause it to happen more than usual. List what apps you are running. Also, clear your messages, emails, call logs, etc..
