I'm having a similar issue to this with my Galaxy Note 4. When I turned all the options off, it worked fine for all apps except for my screen recorder Game Screen Recorder by DGenius. When I attempt to add recordable apps (so that it isn't just recording the 'desktop' or entire screen), it requests to have screen overlay turned on. Except now that I've turned them all off, I have literally no way to access the screen overlay options at all. I've search checked Display, Screen, and Overlay, Draw, Secondary, Screen Overlay, the last which don't give any options. I've uninstalled all Cheetah apps (Cleanmaster, etc) and that didn't solve the issue. How do I get to the screen overlay options without it being raised as an error, because I've tried uninstalling and reinstalling previous problem apps to get it to pop up again and it hasn't.
Edit: I have screen shots of the error page, and the Permissions page, but I can't post them to the forum on mobile and have no computer access.
