A full version app for Android, by Florian Grill.

PSJoy is a tool that allows you to play games on your smartphone or tablet. It works like a regular gaming console, but it does not require any hardware. You will only need a mobile device and an Internet connection to play. 

PSJoy supports all PS4 games that use a gamepad. It also allows you to set up a dual-gamepad for your device.

How can I use it?

The first step is to install the PSJoy server on your Windows PC. Once you have done that, you can install the PSJoy client on your Android or iOS device. You will only need to connect to the PSJoy server and start playing.
