Perhaps its not quite 'dumb' enough for you, and they have yet to ship so no one can really speak to the quality but this product https://clicksphone.com/communicator might fit your needs. I'm thinking to get one myself but not yet decided. Will probably wait for a review or two.

I didn't hesitate to preorder it. Team behind it is really solid and passionate. Hopefully will have it in my hands around Christmas.
