I decided to get a CAT S22 as a smart pocket flip phone. It is supposed to be ruggedized, and so far I haven't broken it. It is slower than cold molasses. But, it works. I have the phone number cloned to my primary phone. (T-Mobile Paired Digits). I wanted something that I could carry around when I'm working and not worry about it. It is a full feature smart phone with a minuscule screen. It has a camera. Not great, but it works.
I have an acquaintance in her 70's or early 80's that complains about smart phones every time I hear from her. She's been hunting down smart phones for quite some time. She seems to get about 6 months out of a flip phone, then needs a new one. I don't know if it is her, or poor quality of the phones.
