I just got my note 2 and while I was pulling it out of my pocket I must have hit some stuff (no idea what) and now on the left side of my screen is a blue, half circle tab. When touched it pulls out a little page that is horizontal (takes up about a quatre of my screen) and has several icons. At the top is my e mail icon, gallery, Internet, etc. At the bottom it shows an edit button. When I touch edit a screen appears for me to drag the icons onto and then the edit button changes to a done button. If I touch done it goes back to a regular screen with the blue tab on the side. The tab is there no matter what screen in in or what I'm doing. I'm curious what it is but more importantly I would like it gone. Please help!
