The tip I am talking about is a nice little program called SensorLock. So what it does is locks all you sensors (I am sorry for my poor writing as I failed Writing 101). So pretty much when a call comes and you are trying to get the phone from your pocket you may accidentally hit Answer or Ignore or whatever without really intending to do it. So thats where sensorlock comes in. It locks the touch screen and buttons until you unlock it with a simple gesture. Please check the YouTube video or give it a try as I am probably confusing you. But I think its a great program that will help many.
