How to solve it?

The volume knob stops working on Android 12 QCM6125

 

If your radio Android 12 Qualcomm Snapdragon 6125 head unit volume knob buttons are working abnormally, below are two ways you can have a try:

 

The First way:

1. Whether the A port resistance value is 15.0K, B port resistance is 8.2K, pull-up resistor is 47.0K and error voltage is 51.6mv?

2. Whether knob reverse and Knob function exchange settings are off? (see as below)

  


 If you are sure that the above settings are correct, then the volume knob still doesn't work, then please adjust the error voltage from 51.6mv to less or much, then see if the volume knob returns to work or not.

 

If you adjust the error voltage from 51.6mv to less, the volume knob can work, please click OK. If you adjust error voltage from 51.6mv to much, the volume knob can work, please click OK.

 

NOTE: After you set the error voltage value, please reboot the head unit. 

 

The Second Way:


1) Please try to disconnect and connect the screen ribbon as below:

 

 

2) After finishing the above steps, please reboot the head unit.
