The PS4 Remote play functionality lets you Play your PS4 Games from the comfort of your Desktop PC, your PS Vita, or on some Android devices. In addition to the official Sony clients, unofficial ports let you use PS4 Remote Play on Android devices that are not supported by the official remote play client, and an unofficial port exists for Remote Play PC as well, with more features than the official client.
The official version of PS4 Remote Play for Android is limited to the devices it supports: Sony XPeria smartphones and tablets. We’ll never know if it’s a plot by Sony to make you purchase their phones, but that didn’t work for very long.
Developer Twisted has been working on an Android mod of the official Playstation Remote Play app. The app lets people use the Remote Play functionality on their Android device of choice. He also released an unofficial Remote Play PC App.
The following routers have been recommended by gamers for the best Remote play experience on your PS3/PS4 and PS vita. In general for Remote Play you are looking for solid Wifi performance and a good range, given that at least your PS Vita will be on Wifi, and potentially your PS4/PS3 too.

There also exists an unofficial PS4 Remote play for PC application, created by developer Twisted (the same person who ported the Android version above).
Remote Play PC (Twisted’s unofficial port) running Injustice, Gods among us.
This unofficial PS4 Remote Play PC application used to live on tmacdev.com, but is apparently not available for download or purchase anymore. Another unofficial client named PS4Play was available at some point in time as well, but there site is down as well.
The community surrounding the unofficial client has published examples of people enabling Virtual Reality (VR) on the PS4 through this client. Or, let’s say, a “poor man’s” version of VR (still impressive nonetheless). The official Remote Play PC probably allows similar things.
Sony designed the PS Vita with Remote play from the ground up, and the PS4 officially supports the Vita. There are however several important configuration steps you need to go through in order to make it work right.
