Hi vignolifabio
What's your phone’s firmware version (Settings > About phone> Build number)
Please kindly test it under safe mode. (safe mode:

Please try to use other different bluetooth device for a check.
Is there any error message pop on when you encounter this problem? If yes, please kindly show me your screenshot.
Thank you:)
