 <p>I guess you mean something like services running in the background and use GPS? So that you don't activate the GPS yourself but it's still running? In that case there's no way I know to get all Apps that are allowed to use GPS in background. You can go to your Settings->Apps and check the permissions which apps are allowed to use GPS.</p> <p>A typicall background GPS user is the facebook app (or google+ I guess). Hope this helps.</p> <p>Edit: Alternativly you could disable GPS when you don't need it so that no app has the possibility to use it in background.</p>
