I'm using a Glass screen protector from Tech Armor https://www.amazon.com/gp/aw/d/B078T1ZZFY/ref=ya_aw_od_pi?ie=UTF8&psc=1
I had the same kind on my Galaxy S8 and didn't have a lot of problems with it. But now it's driving me nuts. It's not as case-friendly as I hoped, at least not on my Spigen Liquid Armor case I'm using. And the oleophobic coating lasted all of an hour.
I have a Tozo case coming in that will hopefully give enough room for the screen protector, but so far I'm disappointed.
