This has happened to me a few times since I got this phone. Every now and then the screen doesnt work. The past couple times I fixed the issue by removing the battery and waiting a couple minutes before putting it back in and powering the phone up. Today it happened again. I went thru the battery pull and this time the screen still didnt come back. I tried it a couple more times and finally the screen came back. Any one have any idea why this is happening? How to fix it?
