First issue is with my vehicle’s Bluetooth system. Playing music is fine, however the vehicle 90% of the time thinks the phone has no signal and won’t let me make a call, unless directly from the phone itself.

Second issue is with my wireless headphones. I do the initial connection, turn off the headphones, turn them back on, and they won’t auto connect with the phone.

The problem is not my vehicle or headphones, as between an iPhone and various other androids, the Oneplus is the only phone with these issues.

I have tried factory resetting several times, clearing cache, changing different settings related to Bluetooth, disabling adaptive battery, downloading the full 9.0.2 zip and reinstalling. You name it, I’ve tried it. To be sure it wasn’t an app or setting on my behalf, I factory reset and went straight through setup not changing anything, and then testing.

I’ve been trying my best for the past 2 days trying to get this to work.
