You would be aware that some apps like Banking apps do not allow you to take screenshots while using the app due toAndroid Security Policy.
WHAT YOU KNOW
It is for your security.
WHAT YOU MAY NOT KNOW
If you thought that the app doesn't want you to save the information on your phone, it is wrong. That'snot why this feature is implemented.
WHY DO I SAY SO
Because the same app may allow you to download your information to your device. Only screenshot is not permitted.
WHY SO
Android allows sideloading of apps, and it is generally accepted that malicious apps make it to the Google Play Store more often than the Apple App Store.
Android provides a built-in way to block apps from recording your screen, so that a malicious app may not watch and intercept your activities in an app that uses this feature.
Since anything related to money is crucial, all (or most) banking apps make use of this feature to protectYOURACTIVITIES within the app.
The last time I tested using screen recording apps, I only got a black image when trying to bypass this restriction. And if I remember correctly, using Google Assistant trick too doesn't work anymore. All known loopholes have been taken care of.
Do you know of a way that still bypasses this restriction?
I know that bro. But you started your post with mention of banking app and then moved on to the incognito mode of browser. As per my understanding and Google search if an app uses such security measure it's not possible to screenshot or screen record the app. You can take pics or record video by pointing another camera on mobile screen.
I used Chrome browser incognito mode as an example so you can test the restriction that I was talking about, since Chrome is a browser most users use, even if banking apps are not the same.
That said, it is possible that apps allows screenshots only in a few pages, such as the one you described - transaction details, while blocking the same in the rest of the app.
These restrictions only add to the security, even if they are not foolproof.
