One thing I find very annoying about Samsung is that it tries to get people to use Bixby (Samsung's "Google Assistant") by remapping their phone's power button to Bixby. Due to the nature of my current project, I talked to many Samsung owners in their 50s and 60s who don't know how to turn Bixby off and, consequently, don't know how to, e.g., shut down or reboot their phones.
