I got a task to buy a smart phone for my grandparents, they are not techsavy but they know how to use basic functions. Iam looking for an andoid because it has language pack i need. I dont need it to have lots of functions, onley a good camera and a big screen. Bonus points if it can be flashed with some kind of simplefied version of android.
In my experience, older people want to use their smartphones forever so that they don’t have to relearn how to use them. If I were you, I would therefore use a mobile phone with the longest possible software support. I think that the Google Pixel 8 fulfils your criteria and offers very long software support among Android smartphones. Given Google’s size, you can also assume that the company won’t go bankrupt before then.
