I have a flip phone myself, but it's not really a dumbphone. Articles like these don't really go deep into what dumbphones are even like nowadays. Usually, they run Android and come with all the standard features like internet and email. Hypothetically, I can even sideload apps onto this thing. The specs are obviously weak, but still a lot compared to a true dumbphone. My phone has 512MB of RAM and a 4GB SSD, but there's also another model of this phone that has 1GB of RAM and an 8GB SSD. All in all, true dumbphones are dead.
