Editing Screenshot blocking (section)

==External displays==
The "SECURE" flag on Android is responsible for screenshot blocking and screen recording blocking. However, it has another purpose: It prevents content from appearing on external displays such as HDMI and Miracast (over-the-air screen mirroring).

Screen contents can only appear on an external screens if the smartphone owner has chosen to connect an external screen. If the owner does private stuff, they should disconnect the external screen anyway.

Ways to solve this would be to let the user chose which apps can appear on external displays, or let the user decide whether they want to hide content flagged by the app developers as "SECURE".

The "SECURE" flag is not just used to hide "sensitive" content, but also by streaming service providers to prevent screenshots and screen recordings, even though there are legitimate purposes for it (fair use). As a side effect, you can not connect your phone to a TV or monitor to watch on a big screen, so you have to hope the TV has native support for your streaming provider.

In any case, the device owner must have the final say.
