I've had one of these https://www.walmart.com/ip/Consumer-Cellular-Link-II-8GB-Red-Flip-phone/735136935 https://www.walmart.com/ip/Consumer-Cellular-Link-II-8GB-Red... since my previous 3G ZTE dumb phone became useless when 3G stopped being supported in my area. It's running a neutered version of android that to the best of my knowledge can't run apps or access the internet but the interface looks and feels very similar to the old Java one running on my ZTE so I think the manufacturer just ported the old ZTE gui to android and slapped it on this one. It's about as dumb (and cheap) as I could find.
