Issue 2. Unless I turn on "Disable hardware overlays" my screen flickers
Issue 3. (more recently) I can't sent or receive text, on rare occasions i can get text in and out though.
Issue 4. I also cant send or receive calls. (side issue is I have no sound unless on bluetooth)
What I see on the screen: The ATT text in the status bar is usually not there and neither is the power saving icon is missing too.
What I have done: *#*#4636#*#* I toggled everything and it seems to work for a second but I'm not sure what its supposed to look like.
(currently have the ATT text back annnnd now its gone)
I have also backed up with CWM and did a factory reset with CWM multiple times in the passed few days.
(ATT text came and went again)
If you have any questions please reply. if you can solve or have any tips please reply too. Thanks!
