I have a Galaxy Note 9 on T-Mobile (USA) updated to Android Pie (Android 9.0) since the update my phone, all my Bluetooth pairings disappear after each restart or power off. Is anyone else having this issue? I did a system restore after updating to Pie. I have reset my network settings per calling into support about this issue to no avail.
I am having the same issue. After every restart I have to go to reset > reset >reset network settings. After reset I have to restore from my backup. I still have to pair all my devices again.
Same here. I lost them all initially and every time I reset the phone I have to re-pair all my devices. Not fun and I have about 10 devices...ugh. I do have the special edition with more ram etc. Not sure if that is in common. But I am tired of this happening. I also did a reset of the network settings and no help either.
Have you tried Settings> Search resetting your network settings. Then clearing your cache partition and unpairing and repairing the Bluetooth devices?
