Why it's my Galaxy note 5 saying I need to turn screen overlay off.

[AC Question]

I am on buzz pack I haven't downloaded any new apps

For several users this problem seems related to different CM apps (Cheetah Mobile). If you have any app by them uninstall or disable it and see if the problem persists.
