@ArvindSingh's solution is not the best one, because you would also disable the focus functionality for the back camera. A better solution would be to do a camera facing check inside the takePicture like that:

private void takePicture() {
    if (CameraCharacteristics.LENS_FACING_FRONT == mSelectedFacing) {
        // front camera selected, so take a picture without focus
        captureStillPicture();
    } else {
        // back camera selected, trigger the focus before creating an image
        lockFocus();
    }
}

For this solution you only need to save the current used facing somewhere like here in mSelectedFacing
