Using Android Teracube build 13.0.5+06dd9ba.zirconia.user, security patch level 7/5/2024.
Randomly, the display goes blank and the unit becomes non-responsive, on/off button will not work. Seems to happen when the phone is in timeout mode.
The only solution is to open the case, remove the battery, reassemble and restart the phone.
After restarting, the phone works fine until the next time the issue occurs.
Any ideas?
