Ever since the Android 10 update. Reboot doesn't fix. Factory reset doesn't fix. Echoes and feedback are horrible. Any suggestions?
?windows 10 update?
Android 10. Oops. Too many 10's.
This is a strange one. We can either log the phone and try to figure out what's going on, but I would probably recommend contacting your local ASUS Support for a warranty repair. The turnaround time should be faster, and since a factory reset had no effect this might be a hardware issue.
Strange that it started with Android 10 though.... Are you sure you factory reset the phone? It wiped all your data and apps?
