Android Tablet - brightness falls to lowest setting automatically
I have 20 android tablets/samrtphones, some Samsung and some Xiaomi, configured with Meraki MDM kiosk mode. Occasionally, the tablets' brightness setting will automatically fall to its lowest setting by itself (kiosk mode prevents users from changing brightness). This requires IT staff to manually disable kiosk mode to increase the brightness on each tablet. Sometimes, when increasing the brightness, the slider will again fall to its lowest setting immediately. This stops temporarily if you enter display settings and turn the Eye Comfort Shield on and off. Adaptive brightness is disabled, eye comfort shield is disabled, and battery saver is disabled. Has anyone else experienced this kind of issue?
I erased one of my devices yesterday and Systems Manager 5.8.7 was installed when I re-enrolled. So far I haven't had issues with the tablet staying dim. Any one know of a way to force the update of System Manager?
