There are some user friendly Android based alternatives out there, since it’s based on open source. Personally I’m running a device with /e/OS, which you can either install yourself or buy a phone with it pre-installed. There are also some other user friendly options out there such as the Volla Phone.

But yeah, iOS is probably a better bet than stock Android, as Apple has a history of being abusive towards their customers in other ways than by selling their data. But crucially both Google and Apple are American companies, so you should avoid depending on their cloud services to whatever degree possible. There’s no such thing as safe data if it is stored by an American company.
