I have a 5. Now that the new Razr+ is out, and they seem to have addressed most of the previous issues, that’s the one I’ll be looking at next.
Why? Samsung software. It’s pervasive and hard to remove, or even often just to disable. And Samsung collects all of the data. It’s crazy how much is shipped back to Samsung servers.
If you don’t care about that kind of thing, the hardware is nice. But I’m looking elsewhere for my next flip phone.
