I’ve bought some cheap Teclast tablets on Banggood a while ago that I plonked on the walls in the house. They Android 9 so still enough to display lovelace on. I then set the panels to only display in a sort of kiosk mode (much easier to do with the latest versions of HA out of the box)
You don’t see the navigation icons and status on the tablet, they only showed up when I tried to do a screenshot.
