Flipcase is another company delivering screen protectors for the Galaxy S7 Edge. Most of the original options that came out in 2016 are no longer available. This is because most glass screen protectors have gaps between the screen. Causing issues for owners that are very frustrating.
Flipcase is one of only a few for the Galaxy S7 Edge that has almost all positive reviews. It's real glass and shouldn't be a hassle to install. Comments online suggest it works great, too. It doesn't hurt that they're only $3.
