Salesman mentioned back cover one too.. don’t understand why anyone would ever need this if their phone is in a case? Please explain..As NewdestinyX mentioned I use the Zagg HD. I got both the front and rear, as well as a polycarbonate clear case. I ended up having zagg re-install it (it's free since its warrantied). The new installation looks 100% perfect, additionally the phone looks great and is very well protected at this point.
