Bought a new Suzuki car and my A23 5g auto-connected to the multimedia system without a pairing request, didn't even ask for a security code! Now I want to unpair the phone as I suspect its interfering with my wireless Android Auto adapter but it won't stay unpaired - I can unpair it both on the phone and on the car multimedia system but it just automatically pairs again as soon as the car starts up. I can find absolutely no 'forget' option on the A23s Bluetooth settings. Suzuki are definite that it is a phone issue. I think this is a serious security issue, as well as driving me so mad I'm seriously considering ditching the stupid phone and reverting to Motorola.
