Sooo I walked into the room to discover my phone in the mouth of my 6month old. Now the little icon on the bottom of my screen that I would have normally tapped to take me to the file of all my applications, is gone. I can't access it at all. I tried hitting settings and going into the applications settings, but I'm not technologically talented, so I really have no clue what I am doing, and would prefer to not inadvertently ruin something else along the way. Help please?
