Document

Whether auto-white balance (AWB) is currently setting the color transform fields, and what its illumination target is.

This control is only effective if CaptureRequest#CONTROL_MODE android.control.mode is AUTO.

When set to the ON mode, the camera device's auto-white balance routine is enabled, overriding the application's selected CaptureRequest#COLOR_CORRECTION_TRANSFORM android.colorCorrection.transform , CaptureRequest#COLOR_CORRECTION_GAINS android.colorCorrection.gains and CaptureRequest#COLOR_CORRECTION_MODE android.colorCorrection.mode .
