He already has a Nokia feature phone. The problem is that a feature phone has more features than he needs, and sometimes requires navigation to perform a task.

He already has a Nokia feature phone. The problem is that a feature phone has more features than he needs, and sometimes requires navigation to perform a task. Also, some of the physical controls are rockers, which he doesn't seem to grasp. If I could at least limit him to a phone app (with no easy way to get to the home screen) with discrete buttons for almost everything and almost no navigation, I think he'd be able to get by better than he does now.
