I think the issue is with your setRepeatingRequest. As far as I know, CaptureRequest.CONTROL_AF_MODE_AUTO should only cause an autofocus to occur once, but setRepeatingRequest will send continuous requests. Try using capture instead:

previewRequestBuilder.set(CaptureRequest.CONTROL_AF_MODE, CaptureRequest.CONTROL_AF_MODE_AUTO);
previewRequestBuilder.set(CaptureRequest.CONTROL_AF_TRIGGER, CaptureRequest.CONTROL_AF_TRIGGER_START);

state = STATE_PREVIEW;

try {
mCaptureSession.capture(mPreviewRequestBuilder.build(), mPreCaptureCallback, mBackgroundHandler);
} catch (Exception e) {e.printStackTrace();}
