Let’s discuss the required items to power up this system.

  1. A Windows Computer
  2. ADB (Android Debug Bridge)
  3. Scrcpy (aka screen copy)
  4. An Android Phone with at least Android version 5.0
  5. A USB cable

I’m going to discuss a brief background of the tools to give you a better insight on what you’re getting your hands on to.

ADB: Android Debug Bridge or ADB is a command line tool used by developers to communicate with an Android device from their computer. You can use it to control your Android over USB from a computer. copy files, debugging and testing apps on your Android devices. A command line tool it isn’t very user-friendly. To solve this hurdle we have the next tool Scrcpy.

Scrcpy: It is an open source emulator tool developed by Genymobile, it emulates the mobile screen on computer desktop in an emulator. It works simply by creating a Java server on the device. The device runs the server and broadcasts the screen on the server using ADB. Scrcpy listens for it through the socket and displays the screen on the console. It transmits the video in H.264 encoding. The desktop console decodes the video.

The installation of the tools does not require expertise and we’ll break down the process to simplify it even more.

For Windows:

First thing, we’ll download ADB package for Windows and extract the files to an easy location on your computer, let’s say  c:\ 

extract directory for adb

We make a new folder ‘adb’ and unzip the contents in c:\adb\

Now we have to download the tool scrcpy which would be used as a server for the video feed from the mobile phone. here’s the link for scrcpy

scrcpy files

The package is available for 32bit and 64bit computers separately and you can choose according to your computer architecture. When the download finishes unzip scrcpy and paste the extracted files in the same directory where ADB is installed i.e. c:\adb\

paste scrcpy in adb

Now the next step requires us to open command prompt which we can do by invoking Run dialog and typing ‘cmd’. When you hit enter, Command Prompt pops up.

run cmd

Change the directory to ADB folder, i.e. c:\adb\

cmd adb

Next, you need to enable developer option on your Android. To do that, go to Settings > About phone > Build number and tap on it 7 times.  You’ll see a popup that says, ‘You are now the developer’.

Now, go back to Settings, where you’ll find Developer options on the menu. Next, tap on Developer options > Scroll to USB debugging > Turn USB Debugging ON

turn usb debugging on

Once, done, connect your USB cable to the Android device and the computer, the device should prompt you to select an option ‘Allow USB debugging’, grant the permission, we’ll need that permission because ADB requires it to remotely run an application on the mobile device.

Now on the Command Prompt, change the directory to ‘adb’ by using the ‘cd’ command and then type the following command ‘adb devices’

devices connected

If you did everything correctly and followed the steps, then cmd should display your device name or a serial number like above.

Now we’re ready to go and start the console. We’ll just type ‘scrcpy’ and hit enter.

emulator starting

Now the console should start and you’ll get a high-resolution feed of your mobile device without any lag whatsoever. You can now use it to work with your device.

You can use your mouse pointer to control your Android smartphone from your computer. The PC’s keyboard works on your Android too. Overall, from all the methods we have seen to mirror your Android screen to PC, this method has the least amount of lag. However, if you play a video on your Android, only the visual part will be cast to PC, the audio is played only on your Android and not PC.

For Mac and Linux

Though Scrcpy works on Mac and Linux as well, the setup is a little bit more complicated. It requires basic knowledge of terminal commands and build commands. if you wish to use it on a Mac or Linux you can check out the XDA link and follow the steps to run this setup on your Mac and Linux machine. We’ll test it on Mac and Linux and frame an easy tutorial for you in future. Until then you would have to either use a Windows or ‘hit and trial’ it yourself.
