Here is a quick tutorial on how you can convert your android phone to be a wireless touchpad and keyboard for your computer. This can be useful if you want to control your PC from far away and do not have a wireless mouse or keyboard.
Please note that you need the phone and computer to be on the same network.
I have demonstrated this video using my phone (Xiaomi Mi 8) and computer (Windows 10).
This will work with Mac computers as well (Just download the correct server software)
