Fix a sideways camera view on the facial recognition screen.
On some Android tablets, the facial recognition camera view appears rotated 90 degrees. A quick setting change in the Kiosk App fixes it.
On the Kiosk App, press Manage in the lower left corner of the screen and log in with administrator credentials.
Tap Time Clock Settings.
Find the Use Device Camera Application setting and turn it on with the toggle on the right.
The Kiosk App will now use the tablet's own camera app, which should show the correct orientation during facial recognition.
