IQ Shield Liquid SmartSkin for S8+
This option isn't glass, and that's because a lot of people struggled with glass screen protectors for the Galaxy S7 Edge. From the curved design to the installation process itself. This smart film is similar to other products but has anti-scratch properties and heals scratches over time.
One of the best parts of the IQ Shield Liquid Skin is the installation process. Your purchase includes a proprietary installation tray that's so easy anyone can do it. Rather than taking the phone somewhere. Not to mention spray solution, squeegee, lint-free cloth, and simple instructions to follow.
If glass screen protectors don't work well or you have a hard time with the installation, give this a try. It's cheap and comes as a 2-pack.
