Hi so here is the issue I'm having. In security menu you get the device administrators sub menu, so I can give admin rights only at first after a factory reset. If I need to give new rights after a few days from that factory reset it won't work like either removing admin right to an app I already chose or adding the right to a new app it just won't let me, its like its frozen it won't register the click to make the changes. And when this happens some the apps that was given admin right does the same it just freeze, it will open and runs but can't do anything in the app. Like my kaspersky antivirus, it auto start and stuff, does it auto scanning but when opening it you can't click anything it just frozen.
