My has been using a flip phone for several years, and needs to be replaced. It was not her primary phone until she moved into assisted living . She uses it ,only for calls. Speed dial is the only function she has ever used, a d was doing pretty well with it but as her dementia symptoms have increased it has become more difficult for her to use. I think a phone as basic as possible would be best. A,larger screen than her flip phone would be useful, and a larger font. Voice mail would be helpful and she may enjoy using a camera. A touch screen would be too confusing. A phone with more functions would probably be ok, as,long as making calls would be straightforward . Basically all she would need is to make calls . The more some the better. I would love to hear suggestions .
