This has gotten to the point where I am ready to throw my Lumia across the room. Live tiles won't update. I can't pin things to the start menu. Ill try to scroll to the top or bottom of my start screen and the icons either won't show up, then will suddenly appear, or will be a blue square then finally appear. The app list will have gray squares instead of the app icons then show the app icons, it's irritating the crap out of me. Anyone know anything about any of it?
