Fingerprint sensor IS REPLACEABLE withohut screen removal, only very difficult and fiddly. I’ve done it in december 2020.
Nice teardown, but the score is wrong. Repairability of this phone is at least 6. I’ve repaired several already. Everything is modular and replaceable. Battery is not difficult to replace, where did you get that it is? You could lower the score by one for how expensive original display is, ind how there are no decent replacement screens, only trash, but the every Samsung should get same -1 for this reason.
