By 2014, 1440p displays began to appear on high-end smartphones.  In 2015, Sony released the Xperia Z5 Premium , featuring a 4K resolution display, although only images and videos could actually be rendered at that resolution (all other software is upscaled from 1080p).  Microsoft, expanding upon the concept of Motorola's short-lived "Webtop", unveiled functionality for its Windows 10 operating system for phones that allows supported devices to be docked for use with a PC-styled desktop environment .   Other major technologies began to trend in 2016, including a focus on virtual reality and augmented reality experiences catered towards smartphones, the newly introduced USB-C connector, and improving LTE technologies.  As of 2015, the global median for smartphone ownership was 43%.  Statista has forecast that billion people will own smartphones in 2020.
