If you turn developer settings off does it go away?

Welcome to Android Central! If turning off Developer Options doesn't help, then show us a screenshot: http://forums.androidcentral.com/ge...ide-how-post-screenshots-android-central.html. You'll have to register first.

That could also be some kind of ultra power saving mode, depending on the device.
