It's worth mentioning that newer Samsung phones and tablets have an eFuse that is blown when you unlock them. This permanently disables some functionality of their separate secure element (IIRC). If you are planning to run LineageOS forever, it would probably not be a big issue, but if you just want to try a third-party OS or ever resell the device, it could be an issue.

Also note that latest Samsung models like Z Flip 7, along with recent models such as S25 who's gonna get the OneUI 8 update will not allow unlocking anymore.
