Well… Anything a generation old for price and not flag ship. Samsung A-something or Google something-a. You can change the screen dpi to make thing more readable.
You can install a custom launcher to have full control over the home screen and just show the important apps like call, text and email. I use pre sale Nova.
Most custom launchers let you lock the home screen too, something I learnt was important for my mother who would CONSTANTLY drag stuff around, get lost and then claim she didn’t go anything.
