Doodlebug450: My simulated Iphone! To make your own background, go into the paint app and draw anything you like! Next, open Settings; and click create your own. This will display whatever you have currently on your paint app as your background!
Thx to @Joberg34 for idea! How to use Touch ID: On powered off UPhone click Home or Power button then press and hold Home button for 2s. UPhone 6 will unlock!
