@afollestad I tried using the following code reported below under the start recording fcn (line 622), but it is not working (although the same procedure was working in another app)? Would you mind helping me, please? Thank you!

mPreviewBuilder.set(CaptureRequest.CONTROL_AE_MODE,

 CaptureRequest.CONTROL_AE_MODE_ON);
    mPreviewBuilder.set(CaptureRequest.FLASH_MODE,CaptureRequest.FLASH_MODE_TORCH);
   
   try {

                mPreviewSession.setRepeatingRequest(mPreviewBuilder.build(), mRecordCaptureCallback, mBackgroundHandler);

            } catch (CameraAccessException e) {
                e.printStackTrace();
            }
