I was just like you, until I was forced to go a few days with my GS7 edge without a screen protector. Edge screens are notoriously difficult to find good protectors for that don't attract dust or peel up at the corners. I was spending way too much money on those things. After those days without a screen protector, I realized my screen was still pristine. Days turned into weeks, weeks into months, and the screen was still perfect. Got my GS8 last Friday, which has Gorilla Glass 5 rather than 4 (the GS7s have this), and all is great so far.
Plus, nothing really beats the feel of a naked screen. It's glorious. Ditch the screen protector and just go with a case. Also, don't carry grains of sand in your pockets, and you're good. Your fingers will thank you.
