Apple tells app developers to disclose or remove screen recording code February 7, 2019 https://techcrunch.com/2019/02/07/apple-glassbox-apps/
Funny enough I was just reading on reddit, an argument about a similar issue with Android, specifically with the Android Protonmail App. They said there is a setting in the Protonmail app that is supposed to disable screenshots but that setting turns itself off when you logout of Protonmail. I knew I had set that button to on in my own protonmail so I took a look and sure enough, it was turned off. So I set it back to on and logged out and logged back in and it was turned off again. So then I brought up 'recent apps' and there was the Protonmail app capture of my last open email, clearly readable. Hmmmmmm.
It's very simple, you simply can not trust apps on smartphones, so I simply do not do anything important on it. So no email, online banking and no social media (only with fake accounts).
Well the point of the argument about the Protonmail app was that Android provides a method for disabling screenshots and Protonmail isn’t implementing it properly.
