Calling bullshit
Did they state what version of Android? Seems since Android 5 the main method of obtaining the screen buffer is blocked unless you are rooted (and screen recording should be the least of your worries). They didn't talk about background recording or foreground recording (big difference). This is little more than mucky clickbait.
Post Android 5 you need to connect to a pc every time and run some PC app that sends some debug ADB commands to get things working. These idiots just lost all credibility....
