My ZTE Blade V8 Pro periodically starts making a screeching noise when connected to bluetooth. When this happens, and I disconnect bluetooth, the sound continues through the phone's speaker.
This may be related to the "Dolby Audio" setting. I keep disabling this setting, and it keeps getting enabled somehow.
When I disable "Dolby Audio" and reboot, the problem goes away for a while, then it recurs. When it does, it seems that somehow the "Dolby Audio" setting has been re-enabled.
I've read numerous reports of this problem, with no replies from actual ZTE employees. Can I get an "official" answer from ZTE?
Has anyone had any luck getting this issue fixed under warranty? I really don't know if this is a defect with my phone, or all ZTE Blade V8 Pro phones.
