Re: [TRACKED AND ALMOST SOLVED] Bluetooth issues

Wed Mar 14, 2018 2:03 pm

Good afternoon. My current firmware, which I installed "BV8000Pro-Blackview-V0.1_2017083_20180105-1104". For three months of different reinstallations and following your instructions I report: using Bluetooth of my car to play music, a call, interruptions occurred every 3-5 minutes, after 20-30 seconds the connection was restored periodically and again disappeared. I noticed that the car completely lost the "BV8000Pro-Blackview" and wrote that I do not have a number of "Bluetooth" devices.

Firmware 20180105 is old and carried a bug on the Background task clear setting wich makes the fix posted in this thread not working as expected.
Please update (flash) your device to the latest firmware (20180308), perform a factory reset, apply the fix posted in this thread and report back ;)

As Nevill suggests, Google's high accuracy location setting may cause BT dropouts because it diverts the bluetooth to scan passing cars and tap into their locations, which is why your car BT connection can drop and then reconnect a second later when driving. This is an Android 7 and 8 bug. Only known fix is to go to Settings/Location, tap on three vertical dots at top right, tap on Scanning and turn off wifi and bluetooth scanning.
