There is a smartphone with anroid 5.1. Another user installed an app from a non-verified source (some hacks for Clash of Clans afaik). To uninstall it I have to drop its administrator rights in Settings -> Security -> Device administrators. The problem is that when I click to uncheck it, device locks and I hear two check sounds (check and uncheck, I suppose).

When I go to settings again the checkbox is still checked. The same behaviour when using safe mode.

How to remove malware-originated administrators?

  • Is the device rooted? – esQmo_ Jan 29 '17 at 22:49
  • I don't even know what does it mean. Just a recently bought one. – shukshin.ivan Jan 29 '17 at 23:07
  • Okay I presume it is not. But did you first try to force-close the app then disable the admin rights? – esQmo_ Jan 29 '17 at 23:09
  • What is a force-close? It is not presented in a list of launched apps, but it generates fullscreen ad popups. – shukshin.ivan Jan 29 '17 at 23:23
  • The adware might be present in the app list. Look for an unusual app name – esQmo_ Jan 29 '17 at 23:32
