@Floydfans here are the links for the pre installed screen protectors
I wouldn't recommend the protector that comes preinstalled for long term protection. The best screen protector out there for Galaxy phones especially, is the Whitestone Dome Glass. It will work with the in screen fingerprint sensor. It's a little bit of a project (watch many YouTube videos on it) and a little pricey but it's absolutely worth it.
In my experience, the two pack sold for S10 by Samsung is no where near the quality as what was shipped on my S10. It's definitely NOT oil/grease resistant and has a strange rainbow-like appearance. I will probably try another brand and increase the fingerprint sensitivity rather than using the 2nd protector in the pack.
