Answer to: Volume keeps turning itself downI spent several frustrating hours trying to find the cause of this annoying problem that recently started to bug my iPhone 4S. Then someone in this forum mentioned about the volume control button getting stuck because something is blocking it. In my situation it turned out to be the protective case (LifeProof), so all I had to do was to reopen the case and reinstall it properly. Voila! A simple fix for what actually was a simple problem!
