Any iPhone users need a convenient on-screen 'back button'?

[Mike Lucey]

Hi Guys,

Just learned about the Halo Back , an iPhone 5, 5S, 6 and 6 Plus screen protector with a built-in 'back button'. I will no longer be jealous of Samsung 5 users
Click gif to see it in action.

This is the Halo Back makeup, clever idea or what?
