Please tell us some basic information before asking for help:
Model Name: Indian 8/128gb
Firmware Version: latest .100
Rooted or not: Not
Frequency of Occurrence: intermittent
APP Name & APP Version (If your issue relates to the app): System bluetooth audio
After latest update, old issues of bluetooth are resurfaced.
Issues I noticed:
1. Sometimes system stops outputing audio via connected bluetooth device. Restarting bluetooth device and reconnecting doesn't do anything. Only option is to restart the phone itself.
2. Whatsapp, Google duo calls can't set bluetooth device as audio output. Whatsapp even gets stuck at 3 seconds call duration. And phone becomes irresponsive.
