Detectors of any sort can only flag expected variations from expected norms. AIs’ goals are to be undetectable with continuing improvements. Detectors help them do this by flagging failures. This is the same way antibiotic resistant bacteria evolve (well, it’s similar).
I limit things to swapping the launcher to Lawnchair, disabling most of the Samsung apps and loading Google equivalents (including gBoard). With the exception of notifications and settings, it’s a reasonable experience. Most recently I did this to a Galaxy tab S8. It’s close enough to my Pixel that it’s not irritating.
