Incipio Plex Glass
Last but certainly not least, for now, is Incipio. Another brand we know, use, and trust. As more Galaxy S9+ screen protectors arrive, and we review them, we'll add to this list.
For now, we're also recommending the Plex Plus glass from Incipio. Each Plex Plus Shield has an anti-scratch coating, anti-fingerprint coating, curved and rounded edges, 99.9% clarity and a static-free finish. That's along with scoring a 9H on the hardness scale and being just 0.03mm thin.
Basically, it's strong, works great, and won't be getting in the way. They make each screen protector a few mm short too, that way it works with a case installed at the same time.
These are the best screen protectors available right now for the Galaxy S9 and S9+, and we'll add more soon. Buy one today and have it ready the day you get your Galaxy. It's worth the investment, trust me.
