You can use your Gmail accounts on different clients. Both Fairemail and K-9 Mail support it.

my bad. I assumed she was older than that. A used pixel tablet is what I’d recommend. It’ll get security updates from Google until June 2028 and will probably continue to get updates from custom roms after that. But it won’t meet many of your other preferences.

Samsung now support their newer devices for 7 years too. But as I said earlier their privacy policy for children is ridiculous.

Yes, but that’s from the privacy policy for their Samsung account specifically. Mozilla already says in the article that finding the relevant info on Samsung privacy policy is a nightmare. So, you need to keep in mind that you’d still be using Samsung flavor of Android and some of their apps. If I remember correctly even something as simple as their calculator app has close to 100 permission.

why not? Also, to answer your question on Android specifically. The only 2 companies that don’t abandon their hardware in a year or two are Google and Samsung. And I wouldn’t recommend giving a Samsung device to a child. https://foundation.mozilla.org/en/privacynotincluded/samsung-galaxy-tablets/

But I don’t think this is a common issue. There is an unofficial list of working apps on here: https://privsec.dev/posts/android/banking-applications-compatibility-with-grapheneos/

pixel 5 is end-of-life. This is the support cycle for GrapheneOS: https://grapheneos.org/faq#device-lifetime

If someone can’t afford buying pixel 6a then getting something that works with Calyx/Divest is probably better.
