Galaxy Note 9 Screen Protector... https://www.amazon.com/dp/B07FXLSTJQ?ref=ppx_pop_mob_ap_share
They've replaced my protector twice, the second time because water got in due to a poor fit.
It's a great company and it works very well.
I've written four four page letters with inkredible pro, the main time i use the stylus. I don't notice any problems caused by the protector.
I use a spigen neo hybrid i got off mercari.

Just dropped the phone from two to three feet on a tile locker room floor today. No problems, it bounced a bit and is fine.
Definitely recommend the amfilm protector- I've used their iPad mini version too.
I'm super impressed by the am Film (tempered glass) screen protector. It goes on very easy (comes with a little guide for perfect alignment) and it looks and feels great, it's also very inexpensive. Highly recommend it.
Over the years I've used several different tempered glass screen protectors. They all sucked. amFilm tempered glass screen protectors are unmatched. Great price. Idiot-proof installation tray. Won't let dust sneak in around the edges. No bubbles/halo/rainbow effect. https://www.amazon.com/Protector-Coverage-amFilm-Tempered-Samsung/dp/B07FXLSTJQ
