BodyGuardz offers what's called the HD Contour PET film. It isn't glass but keeps the Galaxy S7 Edge screen safe. This is a standard screen protector that most carriers sell, only better.
It's $30, and has mixed reviews but with mostly positive results. It should fit perfect, cover enough to keep the entire screen safe and work with cases. And since it isn't glass the installation process is easy enough that anyone can do it.
