I think I deleted some software that allowed me to take and make phone calls on my cars phone system. Does anyone know why my phone will not connect to my car?
Honestly I was going through a Google developer training thing and accidentally did something that messed up my phone settings on my s21 ultra. It's been glitching for months...it's not old or bad by any means, but those files are important. Its been 3months counting and I'm still suffering. Hard reset after you've backed up important files. But if you've been hacked, I would do a clean break.
Hard reset: Press and hold power to turn off phone. While it dies down, hold volume up and power buttons while screen cuts to black and reboots itself. It should come back up to a manual button navigation use volume to scroll. Factory reset.
