Will return. Indeed, according to information from various sources, it is known that Apple plans to introduce a new model with a diagonal of 4 "in 2016. We are waiting.
I think so. Apple is rumored to be unveiling the 4-inch iPhone 5SE this year (March 15). Which outwardly will be similar to the iPhone 5S, and in terms of characteristics on the 6 / 6S.
I don’t want to predict, but I would really like a new model, comparable in size to the fifth. Large screens are somehow very closely associated with androids, and do not look at all as pretty as the fifth generation iPhone.
