Mainstream smartphone operating systems (Android and iOS) let applications arbitrarily disable screen capture, screen recording, and screen mirroring to an external display such as a television or an MHL connection to an HDMI monitor.
I am surprised smartphone users have been conditioned into accepting this ownership violation as a "normal part of life". It is not.
As a device owner, you should be able to screen-capture anything that appears on your screen, without exception. App makers have no business deciding what you can screen capture.
Two well-known examples of screenshot blocking and screen recorder blocking are the , and .
The first one probably only intended to prevent incognito mode from appearing on external displays such as a television, which is accomplished though the same feature as screenshot blocking and screen recorder blocking (). So screenshot and screen recorder blocking are apparently collateral damage.
Samsung also added the "secure" flag to their lockscreen key pad in 2023. The goal of this is to prevent it from appearing on external displays, so screenshot and screen recorder blocking are side effects. There is no reason to prevent the device owner from screen recording the keypad if they voluntarily wish to do it, which can be useful for a demonstration or bug report, using a temporary passcode.

And regarding WhatsApp profile pictures: Screenshots of profile pictures are not privacy violations and never were, but have legitimate reasons such as preserving good memories.
Everyone knows that one should not upload something onto a visible spot on the Internet that one does not wish to be preserved by others. A profile picture is such a spot.
A privacy violation is, for example, . Here, developers are being coerced into disclosing personally identifiable details (including home address!) that they probably wished not to, in order to be able to release applications that work on most Android smartphones sold (network effect).
But a profile picture is something one voluntarily chooses to make public, and not even a mandatory requirement to be able to use WhatsApp. Not a privacy violation.
Ironically, this comes from Meta, Inc. - one of the biggest data harvesters in history.
