My mother is 72 has early stages of dementia, and her sight is not bad but not great. She has a iPhone 6s that’s been put through the ringer. I plan on upgrading her soon. She will not take any other phone besides a iPhone. (Got to love her for that.) I am wondering what would be best. It has to be durable, and have a good bright screen. She loves my 8+. But with as hard as the floors are in her nursing home I would be afraid of the glass breaking. I am thinking a 7Plus and a otterbox case. What would you get? Any advice? She has to have a cell cause the nursing home charges a ton for a call. Thanks.
