                          I have an AC82271 Android head unit on Android 12. I went into engineering mode (by inputting 56789 as the PIN on the factory settings screen) to increase the mic volume, but it just immediately went back to zero even though it says it saved successfully.

Can anyone explain how to save the settings, please?
