I keep getting this toast message that keep popping up every few seconds saying "Can't connect to (Mac address) "
I can't really figure out what's causing it, just that it's coming from the system and I speculate that it's a Bluetooth Mac address. I tried looking at all the Mac addresses of the Bluetooth devices I've connected to and none of them match.
Its super annoying and the only want to get it to stop is to reboot my phone.
Seems to come back if I open the Bluetooth settings.
I already tried clearing Bluetooth data and cache with no success.
did you figure out what is causing the popup? If not, try using the Nice Catch and enable Toast History. I think this should be able to detect what is causing that popup.
