TechConfigurations has uploaded a video on YouTube showing off impressive renders of the Sony Xperia XZ4 based on numerous alleged leaks and rumors. The smartphone's display is expected to offer a game-changing 21:9 aspect ratio, so not only will the device be tall and slender, it will also be able to play widescreen movies without any black bars at the top or bottom (letterboxing).
