I mean if the goal is to prevent potential malicious apps from taking screenshots automatically; instead of saving a clueless user from themselves or worse getting in the way of legitimate users I believe that the proper solution is to disallow programmatic screenshots while still allowing screenshots when there is the correct button press (and ensure that this cannot be emulated). Windows reserves ctrl-alt-delete as a direct signal to the kernel for security purposes. Why can't android do the same?

> the proper solution

includes the ability from a user to take screenshots programmatically in case of need. You do not want third parties to be able to; you want the User (yourself) to be able to.

It's really stupid idea, that results in photos of sensitive information displayed on my device on other devices that I don't control and sensitive information wrote on paper in random places.

Password fields are inputs. Screens are bi-directional.

Then ask for my fingerprint after screenshot is made.

So in other words, the developers of Android could not figure out how to design a system that could distinguish a screenshot that was initiated by the user versus one initiated by software.

Very impressive.

i mean, security in depth is a good thing to me.
