After update to Marshmallow focus sound are missing?
I can try to find some info on this, on the z5c there is a focusing sound only when sounds are enabled in camera settings and the phone is not set on vibration mode.
@Rico2 The information I have:
After updating your device to Android™ 6.0, you might notice that there is no sound when you press the camera key halfway down to focus. The sound has been removed to highlight that we have increased the camera focus speed.
