iPhone 12 mini Bluetooth Connectivity Issue
I have recently purchased iPhone 12 mini and restore the contents from my old iPhone 7 backup, post that i'm not able to connect to my Sony external 2.1 speakers through Bluetooth. Upon checking further with Apple Support, they have suggested to factory reset the iPhone 12 mini and try to check the connectivity again, post that also i'm facing the same issue again.
Below are the observation, if any of them faced the same issue, pls help on the same.
