Hi dear! Unfortunately it looks like an hardware fault. You'll have to contact your seller to have your phone replaced/repaired under warranty. If you bought the phone directly from the Blackview Official Store, please contact email@example.com as she will help you sending it back.
Confirmed as software issue from my end. Got a 6800Pro for the kid. Straight out of the box, earpiece wasn't working Did an OTA update, and now it works. Will monitor to see if problem persists or reappears
Let me die on my own terms, let me live and let me learn Now I’ll follow my own way, and I’ll live on to another damn day Freedom carries sacrifice, remember when this was MY life
