I'm still using my "dumb phone" from 2010. I like it cause it has a physical keyboard, a long battery life, and I can drop it without worrying about breaking the screen. Plus I don't have to worry about the privacy issues that come from apps collecting data.
Honestly the only feature I feel like I'm missing out on is GPS. But I've actually found that not having GPS improves my sense of direction, since I force myself to actually learn the map of my surroundings instead of just always relying on the phone.
