When I try to uninstall the app I got this message:
Can't uninstall because this package is an active device administrator.
In the same window I have a button: MANAGE DEVICE ADMINISTRATORS
When I follow this button I'm in Device administration settings. (normally you can reach it when you follow: settings -> Lock screen and security -> Other security settings -> Device administration settings) There are three items each of them have a switch on the side, which is turned on. When I try to unswich AirDroid, I got after some seconds the error message: Unfortunately, Settings has stopped. Also I'm not able to uncheck the other both items, but there is a different behavior.
I try to solve this error by cleaning the cash with no effect.
I like to remove the app because finally I don't need it and it consume a lot of battery even when I don't use it.
I have a Samsung XCover 3
with Android 6.0.1
and Kernel 3.10.9
