A:AnswerBigger screen real estate, Face ID 2.0, A12 Bionic chip, faster processor, faster LTE bands, better camera, better battery life up to an hour and a half.
A:AnswerYes to both questions: The screen is OLED and it is 6.5". It also goes all the way to the edge (there is no border like some of the older iPhones). It's a great phone - I love mine. Hope this helps!
A:AnswerWorks fine,but I would not buy this phone. It is expensive, out of production already, I believe, and mine makes a clunky sound. Buy the newest iPhone. It is cheaper and the camera is supposed to be super.
A:AnswerAny iPhone that is at least 6 inches would be good for elderly, as it has bigger resolution and text. Personally, I would go with iPhone XS Max 64gb.
