[AC Question]

So i'm trying to unistall DU speed booster which is a device administer but when I got into my setting and try to uncheck the tick my settings just stops and says "Unfortunately, Settings has stopped". Anyone know how I can solve this problem.

Welcome to the forums. You could try booting into safe mode first and then uncheck it from device administrators, clear data and uninstall. Tell us how it goes.

Check whether all permissions you enabled like accessibility, while installing the app are left enabled. If by some means they are denied enable them again and then try deactivating the device administrator .It worked that way for swiftly switch app.Probably will work for all apps in that fashion.
