I have a droid 2 global that i got from a friend. It was working perfectly for both me and for him before i got it. Then all of a sudden it started acting up. It would not wake up. I would press the lock button on the top any it would work but when i tried to wake it up by pressing the button again only the back-light comes on and no screen. But if i pull the battery and turn it on it works again until i press the lock button fully functional. I have tried a data/factory reset still same issue occurs. Unfortunately I do not have insurance and the warranty is void since I am not the original purchaser. Any suggestions on why this might be happening and a solution for it?
