Hi there! You can refer to the BV8000 Pro workaround, as it should work in the same way:

0) Consider updating your device to the latest firmware and performing a factory reset after that

1) Go to "Settings" -> "Background task clear" and whitelist all your 3rd party apps wich need bluetooth to transfer data (i.e. samsung gear app, veryfit app and so on..). By doing that, they will be allowed to run in background even if the smartphone is in deep sleep state.

2) Go to "Settings" -> "Battery" -> "3 dots" in the upper right corner -> "Battery optimization" -> select "All apps" from the dropdown menu and disable battery optimization for every bluetooth service app, as
- Bluetooth MIDI service
- BT Tool
- Bluetooth sharing

and for every app needing to use bluetooth to transmit data, as
- Phone
- Phone services
- Call management
- Phone/Messaging storage
- your 3rd party music player
- other telephone dialer apps
- fitness band apps and so on

3) Only if the previous steps doesn't solve your issue, ALSO:
- Go to "Settings" -> "Battery" and disable "Standby intelligent power saving"
- Go to "Settings" -> "Duraspeed" and and disable it.

4) Only if, again, the previous steps still don't solve your issue, ALSO go to "Settings" -> "Battery" and set your device into "High performance mode"

Hi,
I have a similar problem with my BV9000Pro (which in every other respects is a fantastic phone!!), I can connect it to the car for a short period but it keeps disconnecting after a short while. The only way to reconnect it is to switch the phone off and restart it. I have tried resetting the phone to factory setting, upgrading the firmware to the latest one, doing all the suggested solutions on this forum but to no avail! I have tried with different phones and they all work with the car, so the issue seems to stem from the phone itself. Will Blackview issue a patch for this please?
