Well, my Galaxy S22 (from well: 2022), which still works great will no longer receive _any_ updates after February 27, so I'll have to get new one, or potentially suffer open security holes in the future.
Also, even now I only receive security fixed on a quarterly schedule.
Still not keen on switching to the walled garden - I like the apps I have, including custom browser engines. I like having F-Droid with open source apps.
Will probably get another Samsung, as they have extended updates to 7 years for newer S models.
