So I'm like your wife. I need my phone to be fast in the first place, then it's enough for me to have those features it offers, not more (I would definitely catch all kinds of viruses, 100% sure!), delete sth for sure or drown it like I did with my last Samsung. Fortunately, almost all iPhones are water resistant. I can even wash mine with soup, then just eject water with https://apps.apple.com/us/app/clear-wave/id1557211189 and continue using it. I'm not afraid my data disappear or micro SD to be damaged.
