I’d double check that language you need isn’t already on iPhone. They’ve added pretty much every language spoken by at least 100k people.
iPhone is really the only choice for the computer/smartphone illiterate. You can’t easily put the device in an unrecognizable state, you can’t install a launcher that drastically changes the GUI from the app store. iPhone justifiably gets tons of shit, but this is the exact use case it’s designed for. They also have really good accessibility features, and they actually work in apps.
Android has tons of benefits, and I’ve had only android for the last 14 years. I think if you are planning on removing the settings app all together, you know it’s not a great choice for them.
