Any time I'm on my phone and I stand up to walk in the other room without hitting sleep, when I look at my phone it has been activated. It's really annoying because it happens even when the keyboard isn't open, on web pages such as blogs and news articles where its not even possible to type. I shouldn't have to hit sleep just to stand up and walk into a different room or even just create the most basic amount of movement. Makes no sense. Must be why they created ShaketoUndoKiller, can't wait until they update it for iOS 8.
