How to Unpair a Bluetooth Device from Android phone?
Bluetooth is a short range wireless technology which enables wireless data transmission between two Bluetooth–enabled devices located nearby each other. And while pairing devices is easy in Android, sometimes you need to unpair Bluetooth devices.
You’d want to unpair Bluetooth devices, for example, when you’re troubleshooting a connectivity issue, or Paired devices can also be unpaired on the Android smartphone if the respective Bluetooth connection is no longer needed.
How to Unpair Bluetooth Devices
Open Setting and tap bluetooth.
Click on the small right arrow located near the name of your Bluetooth device.
Select the Unpair option.
