Floating-Back Button Concept

I'm a one-handed iPhone 6 user. I'm lazy and always annoyed when I can't reach the Back-Button without repositioning my Hand.

I made a Prototyp of a "Floating-Back Button". The idea is, that you can TouchMoveLeft anywhere on the screen to navigate back in the App.

I've written some more words on Medium.

Let me know what you guys think. :-)
