I ordered a WhiteStone Dome temper glass screen for mine. It'll be here next week.
They're pricey, normally $45. They also take time to install but the have adhesive on all the parts that the screen cover and should keep air bubbles from getting in. They don't have the lifetime warranty like iCarez and others
I put one on my sons S8+ when he first got it earlier this year and it's silky smooth
amazon has them for $30 so I went ahead and got one for the X since they make it.

Here's a guy on YouTube installing one
I have the iCarez in the redbox that I haven't installed yet. I'll probably send it back as long as I don't screw up the WhiteStone install
Plan to install it before I go to bed and let the adhesive finish curing overnight and then put it in the case when I wake up.
