i believe the other party will be informed by snapchat if you took a screeshot of it.

By the way that's a really horrible feature of Android (don't know about iOS). I never gave permission to any app that it could be aware of my screenshots, and yet one of my contacts asked why I screenshotted their message. That's not the business of apps to know, at least without permission first.

I'm not certain with regards to Snap, but I suspect either iOS, or an enterprising app developer, has a function to block screenshots from working.

Specifically when using the Sky Go app for streaming TV, screenshots come out black.

You can take screenshots without the phone knowing (or at least the app knowing) with a app [On an unrooted android phone]

Which app?

It's called private screenshots or something to that effect, basically it adds a button to the GUI above the app.

Why are you screenshotting a contact's message? Android actually can block screenshots of copyright content as well now.

Why does it matter why I was screenshotting someone's message? It's on my phone. Screenshots are a function of the OS, and not the application's business.

Could it be argued that the content of any message I send directly to you is my creative work or intellectual property?

Is screenshotting a message proof of intent to reproduce?

If I don’t use an ephemeral messaging service am I giving implied consent to reproduce?

They go out of their way to detect root and block the app on Android, but I'm sure there are counter counter measures regardless.

Yeah, airplane mode, make the API call fail, reset local state before re-connecting.

Plus, the impossible to plug analog hole... taking a picture of your phone with another camera.

but you take a quality loss...

Did they ever plug the adb screen capture hole?

I typically just take a photo with another device when I need a screen shot of an app with screenshot protection.

Ok, then take a photo of your screen with another camera.
