But if you follow the Zagg support You Tube instructions http://www.zagg.com/us/en_us/support/install_help_center - go to link «Invisible Shield HD» then it becomes clear & the screen protector is straight forward to fit.
Have applied to both my & wife`s S7 Edge`s both no problem - fitted 2 weeks ago now. No air bubbles, both stick well to the curved edges.
Very slight lifting at corners when put in my phone case «Spigen Tough Armour» but not so much that it is a problem, but no lifting for my wife`s phone «Caseology» case.
So overall, very pleased with the protectors & recommended
