Are you really getting updates though? Samsung latest phones are expected to be getting updates for 7 years but as far as I know the s10 range isn’t officially supported anymore. Samsung don’t need to provide security updates to your phone anymore. I think the last one was Q4 of 2023 and it made the news because it was unexpected.
Total ordering doesn’t mean that the order is strict though. You can have multiple individuals with the same level of gayness.
Total ordering means all elements are comparable (=< would be a suitable relation), not that all elements have their individual rank (< relation).
A spectrum implies that the set is totally ordered but not necessarily strictly ordered.
