OK, first, make sure you have an S4 Active and not just an S4. This forum is only for the Active. Second, use a more descriptive title for your post so that someone with a similar problem can find it when doing a search. Lastly, your question makes little sense. Nothing on the screen when? Disconnected from what? What will what? To help you we need more info, but make sure you are in the right forum first.
