I found what the issue is. When you rooted were you on KG2 firmware? If there is a mismatch between the kernel and the rom some users have experienced screen issues. Ya flash back the stock rom in odin. Weird...
If that doesn't fix it then feel free to PM me. I'll help you get this fixed. It shouldn't happen.
Yeah I was, So when using odin what file am I going to use? I have the .zip that's in the first post but Odin doesn't read .zip. Sorry for all the questions I'm and old iPhone guy and I'm still getting used to the Android world!
