You should also check whether changing exposure compensation is supported using https://doc.qt.io/qt-6/qcamera.html#supportedFeatures-prop -

I try to console supportedFeatures is 32 in hex is 0x20 that means it is only support FocusDistance. Qt's camera also supports too few features on Android compared to Java.

What Qt version do you use?
