So my grandmother and I share a Samsung Galaxy Tablet and she recently downloaded something (which she doesn't remember what it was) that changed the layout/format of the home screen thing. So this is how it was originally: And you could slide left to see the apps. But now it's stuck like this and I don't know how to get it back to how it was originally: It has 5 tabs at the top; a heart tab, games tab, apps tab, system tab, and then a little green genie guy. PLEASE HELP! I want it back to the original format and I have no idea what to do.
