Phone :- Galaxy Note 10+ 5G
Android Version 12 with security patch level 1 March 2022 "Software up to date"
In recent times when I start my car, the car thinks it is on a call .. ie the radio is silent, the car displays a call in progress to the 1st contact. If I look at the phone itself, no call. If I switch off Bluetooth on the phone the call clears and radio resumes. If I switch Bluetooth back on, the phantom call re-appears. If I reset the phone, sometimes it clears the fault and sometimes it comes back. Even if it does clear the fault, the fault eventually recurs usually after a couple drivesor days later. I have just cleared the cache and will see if that helps. Weird fault. Up until this recent issue, I haave had years of no issues.
If I recall correctly I had a similar issue and this fixed it:
Developer Options --> tap 'Turn off A2DP hardware offload'
Hope this helps!
Developer options is not available on my phone [Note 10+5G with current firmware]. . However I have managed to clear Bluetooth Cache and Data and re-pair the devices. The problem has returned.
