How can I get rid of that annoying white circle in that black square
Since Oct. 7 last I have a 5S. Before had a 4S. About 4S no complaints, so the 5S maybe faster, better cam and so on but what I really hate it that stupid white circle in a black square you can move around on your screen. However when you want to open, for instance <messages> and that white circle is very near, messages will not be opened but a uselless black sub scrn with favorites, Siri, Device, Home. How can I get rid of that or delete or move it, it will no longer be visible on my scrn.
iPhone 4S, iOS 6
