The last phone I had before I got an Android phone was an LG EnV2. I still have the thing, it still turns on though no networks support it and the battery is toast. Sometimes I just hold it in my hand for a few minutes because it’s just such a nicer thing to interact with than my S10e.
I don’t really count it as a “dumb phone” though. I had some Samsung slider before that that really was a “Camera phone.” Effectively no web browser, no app ecosystem at all, you could barely get the pictures it took out of it. The EnV2 was USB, there were games and things you could get for it, it had some email and web capability.
Then I got my LG Ally phone running some android version from before they started naming them after sweets, and it’s all been downhill from there.
