It's me again do you see the AR Zone App anywhere most likely in Samsung folder also go into settings and try to add the camera to the Permissions see if that does anything
Just came to me go to Settings-Battery-Background Usage Limits look to see if it is in the Deep Sleeping Apps first if not check Sleeping Apps if Deep Sleeping it will disable
it's not listed in the battery app as asleep or deep sleep. you were on to it in your previous post. the app does not appear any where. I guess I removed it some how at some point. werid that it's there in settings and the tab in camera. I can't find away to reinstall or re-initiate it.
