I was wondering if there is a way to mirror my screen of the phone to my pc using the same wi fi connection, like you can do with a smart tv; Do I need to download any special app or program for pc?
You can try AllCast witch only require a working Wi-Fi connection.
It works pretty great for me (Xiaomi Redmi Note 4 Pro, Android 6.0) :
Make sure both your phone and laptop are connected on the same wireless network and then :
- Open Mirror Beta and select your computer
AllCast Receiver will show up on your computer mirroring your Android screen. Hope this will work for what you need.
