We don't need smartphones with 4K displays yet. Here are a bunch of reasons

This will put Sony in a field that hardly any other manufacturer has ventured into before. Currently, Samsung is the maker behind some of the phones with the sharpest displays, namely the Galaxy S6, S6 edge, S6 Active, and S5 LTE-A, all of which boast pixel densities of 576-577ppi. Yet, Sony is allegedly aiming past the 800ppi frontier despite the fact that it doesn't even have a phone with a Quad HD resolution (1440 x 2560 pixels).

Despite that there's little not to like about the evolutionary jumps we witness in mobile technology, there are a few reasons why we don't need phones with 4K displays. Here are some of them.
