I’ve recently been having spotty connection with Anker BT devices through my Moto Z2 Force Edition. I’ve found that disabling location services helps (sometimes). Is there anyone else out there that has an issue with BT connection associated with location services? Just curious.
Location Services interfering with BT?
Only did a quick look, but it looks like a common problem after OS 8.0 Oreo update. Might be able to try some forums advice and see if it helps.
What I found out:
My dab+ radio reception is sometimes interfered by bt.
Also wifi ist disturbing dab+ and bt sometimes.
I think 
Everything which is “broadcasting” might interfere other
transmitters or receivers.
