The name of the app is unknown but when I have an app failure I ask the author or company about it.
Recently I had d/l an app from Google store. After installing it, I was faced with an error about overlays. Never heard of this and after 2 years with my Nexus 7-13, never had any errors. I was told by the message to go to my settings and then apps...that is it. Doesn't tell me what to do there and how to get rid of this problem. i deleted the app. I would appreciate if someone can explain this overlay in layman's terms, so if I get that message again i would know what to do?
