Don't go for the armour glass type you bond over it with UV resin and put a weight on fingerprint sensor while it cures type, unless you like the idea of mounting your phone in a holder and squirting a precise amount on the screen and removing a plastic wedge balancing overscreen on so it drops over screen, then you got to get air bubbles out and apply weight before drying with a supplied USB UV light.
It's tricky and can be messy with reduction of screen sensitivity even with settings adjusted.
I haven't had a protector on mine and it's always pure luck when you drop a phone, protector or not. Mine has scars but has survived.
