I personally own Moto G4 Plus and all of a sudden I was not able to enable Bluetooth. If I switch on, the switch button will be enabled and nothing happens. If I go back and navigate the to the Bluetooth screen again, the switch will be still disabled. So how to solve it??? Here are the simple steps which will reset the app preferences.
- Go to Settings -> Apps
- In the top right corner, click the 3 dotted menu button
- Click Reset app preferences
- Enjoy !!!
