If your running a custom aosp based rom on your Xiaomi mi3 you can install the remote play app and play your ps4 on local Wi-Fi and over internet or LTE. Problems with internet and LTE on android 5.0+ at the moment. Not sure if this works on miui os if you try it on miui please post results for other users. Here's the thread for remote play and instructions for install and getting ds4 controllers working in posts #1 & #3.
