Redmi Telecom uses Bluetooth headset to listen to songs after locking the screen. Why did it suddenly switch headphones to sing ~ pit it ~ ~ ~

This may be caused by an application software conflict. Please back up the important data (contacts, text messages) in your mobile phone. Notes, etc. ), and then open Settings ~ Backup Reset ~ Restore factory settings. Try again and see if this phenomenon still exists.

If there is no such phenomenon, the application you downloaded should be in conflict. I suggest you check it carefully.
