Hi guys huge fan of the show I noticed that on the show Darren uses Vysor I just found out a free way to screen mirror on phones that don't normally support it without installing anything on the phone - all you need is software on the PC.
Basically all you need to do is download the 2 zip files from the description from this youtube unzip them both to the same folder such as "C:\Mirror" and overwrite the existing files then create this batch script on your desktop:
cd C:\Mirror
adb devices
scrcpy
Hope this helps!
