I got this one, it's a film. Super easy to install (if you follow the video instructions). I had to reprogram the fingerprints and it takes a fraction of a second more to read them, but no other issues so far. Case friendly.

I change back and forth between two Spigen cases (the Ultra hybrid and the Crystal glitter). I also use (with zero fingerprint sensor issues) this screen protector: https://www.amazon.com/gp/product/B08CC5WBV9/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1. It works, easy to install and really affordable.

I bought these when the Note 20U first came out, they are affordable, durable and work great with the fingerprint sensor.

I bought this one of of Amazon. Been on my phone for 4 months, no issues.
