I used a nokia dumbphone and it was awful. Not awful due do a lack of features, but awful due to how poorly those features are implemented. Kaios is teal garbage.
But the form factor was lovely, and physical buttons are so much more precise and comfortable to use than a touch screen.
The phone that I really want is a small smartphone with physical buttons for typing and navigation. As far as I am aware that is something that is not made these days.
