Tell HN: iPhone mirroring on iOS/macOS breaks screenshot protection on all apps

Hi, which app did you see this on? WhatsApp is a big one that comes to mind.

It makes apps like Snapchat, Telegram and other apps that detect and prevent / block screenshots useless now.

I heard that Apple knows about this issue (via Feedback Assistant) and their development team said they won’t fix it.

Couldn't you already do that with a USB-C HDMI cable? Stream the screen and record it.

This is always a very interesting topic for me. On one hand, I would like apps to be able to enforce rules like “no screenshots” or at a minimum “screenshot detection”. On the other hand, I want my phone to do what I ask you to do and not be forced to follow arbitrary rules.

Example: I don’t want someone to screenshot my Snapchat message but I don’t want my bank to prevent me from screenshotting the app because of “security” (aka security theater).

I don’t know how you make those two concepts work together.

One random thought that I just had is that when an app uses DRM it just show a black screen when you screenshot. I wonder if could implement that for things like Snapchat to get the same protections.

screenshot protection is a lie

Google has had mirroring in the form of Casting for like a decade.
