Wanna know what's even more fucked up? Few years back, I had exactly this problem. Searched the internet for a solution. Guess what?

Enable Google Voice Assistant and say "Ok Google. Take a screenshot." Google magically has the rights to make a screenshot on the App that doesn't let you, the user, take the screenshot.

Next phone I get is gonna be something with a alternate OS, no Android or iOS.

Like, its my phone, and some app can just decide to disable a fuction of my phone.

Is it your phone though?

I hate this "feature" of the Dexcom GCM app. They seem to believe that HIPPA law prevents me from sharing my glucose readings with anyone I choose to.

To send readings to people, I can't screenshot the app but I can screenshot the notification which contains the same info 🤷🏼

iPhone absolutely has this concept

I agree that it's infuriating! I downloaded an LSPosed module called CaptureSposed that overrides it.

It shouldn't take a specific module hack on a rooted phone with a custom OS with an unlocked bootloader to get this functionality back.

I hate the whole bloody smartphone ecosystem for shit like this. Microsoft Palladium was widely seen as a nightmare scenario when it proposed ceding a bunch of user control to the OS and app developers a couple decades ago, even by the mainstream press. It seems Apple and Google used it as a roadmap, likely because people don't know how to use computers, and that doesn't seem to be improving.

The part of the modern mobile OS security model that does have merit is that apps aren't trusted. The PC model, even in multiuser operating systems with fancy permissions was that apps are user agents which are always doing something the user asked for, and therefore trusted as much as the user. The glut of spyware for Windows in the early 2000s proved that false.

The fact that somebody else doesn't know how to use a computer shouldn't force me to cede control over mine to participate in the modern world. Root is a bit of an escape hatch, but it's a blunt instrument on Android, and Google tries to help app developers stop me from using that as well. I'm starting to feel like Richard Stallman was right about everything and I should go be a digital hermit, only running software I compiled from source.

Soooo... Any Magisk module that allows one to bypass this?

The security argument is a lie, I think. I think websites like Netflix like these features so it's difficult to approach copying a video.

If security were an issue I don't think you'd be able to copy text to the clipboard in situations where you can't screenshot.

I get banking and financial apps doing it. But shopping apps yea, wish we had a permissions override

I've seen public transportation apps doing that to curb sharing the ticket/barcode with someone else.

There's an option in Developer options that'll allow to bypass that setting

Edit: this is on lineage OS but I can't find it in version 21 maybe it's on 20

Yep it's bullshit I hate it too.

My doctor's app does this and it annoys the fuck out of me. I get test results and I want to share them with my wife and it's like nope.

I understand that for security compliance reasons. But beyond that, yupp. It sucks.

Drives me nuts too! Signal at least has a toggle for it, so the user can decide. I wish more apps would do the same, maybe with a pop up warning explaining the risks.
