Anyone have intermittent Bluetooth disconnects ?
Happens in the car and with headphones.

sometimes i have it too and need to restart phone to connect...

What's your current firmware version?
did you perform any update?
or the problem just came out suddenly?

Current Firmware : BV9000Pro_FHD_blackview_VO.6_20180104
No updates where made , no update available currently

you can try to enter the factory mode to reset your phone to see if it works.

Im not resetting this phone. This problem has been happening since I got it new 2 weeks ago.
Perhaps the next firmware update will rectify this problem
