I have had a Razer Nabu X for almost a year and have been using the Nabu app on my Galaxy Express 2, which runs on KitKat 4.4.3 so I had no problems with permissions. However, not that I have an S7 edge and manually have to give permission, when I try to login into the app, it tells me to accept a few permissions, but when I select "allow" it says something in the lines of "Turn screen overlay off" What should I do ?
