I put armor suit case friendly version on my sister's and mom's S7 Edge and it works fine. It just takes patience to apply it being that it's a wet application, but it works out well. They even have a YouTube video explaining how to put it on.
I second armor suit. It's a film type protector that goes on wet so it takes a little time but your patience will be rewarded. None of the so called tempered glass protectors a worth a #$%^ due to the curved screen of the edge.
ArmorSuit is actually the first and only screen protector for the edge screens that actually worked! Zagg, BodyGuardz, and whatever else, were all fails when I tried them.
