To be fair, most skinned Android variants are really horrible. My whole immediate family uses Android phones, but half the time I just don't know how to quickly tell them where an option is because I've used CyanogenMod/LineageOS on all my phones, and they're using Samsung's take on Android, which is shockingly different. Worse yet, they often are on much older Android versions than me which results in even more differences. Settings categories having different names is the biggest problem. At least on some newer Android versions there's a search in the settings so you don't have to guess where stuff is as much.
