I have a couple Samsung Galaxy A8 (2022) tablets set up as control panels around my apartment for Home Assistant. They cost a little more than $100 on eBay in very good condition. I don't think LineageOS supports this particular model, though, but I didn't bother since all it does is display a webpage. One of the things I like about Samsung tablets is that they have a "Battery saver" feature where you can restrict it…
I do this with an old samsung phone I have, but I can't do updates on it, because on that model samsung included an overlay with ads along with the updates. So I see ads (even videos!) instead of my simple html page, or on top of it. It's terrible!
Can't be too old as you are still getting updates.
