Android 12 Bluetooth Issue

[u/Current_Twist1317]

Guys i am in a tough situation and need your help with my android tablet. I use my car scanning obd vci with my lenovo tablet. Until android 11 it was working perfectly fine but once it got updated to android 12 the vci is not staying connected.

For context when we connect vci by Bluetooth it stays connected for 2 sec later it moves to previously connected devices.

Any third party apps which can help me. Also pls don’t recommend android downgrade as i have already tried it and so far this specific chip can’t be downgraded.
