So quick basic question really. I have a Samsung Galaxy Tab 2 7.0, and I want to root it, see how I like it, and if I do, I'd root my Samsung Galaxy 4 as well. If I do root them, will it format the device so it's a clean slate, or will all the apps and various things I have saved to them still be there, and I have to uninstall all the shovelware that comes preinstalled?
