A latest report from WABetaInfo reveals how WhatsApp users on iOS Beta have begun seeing this Screenshot Blocking feature in the 22.21.0.71 version. With this feature no one can take screenshots of photos and videos meant to disappear with one view. Screen recording is also expected to see restriction. The idea fuelling these features is maintenance of privacy for users. An all new pop-up will pop on the screen to block screen recording.
Summing Up
Unlike Snapchat, though, no user will get notified when someone tries capturing the screen. Also, the possibility of clicking the image of the screen on a secondary device still remains open. Only time will tell when this feature finally launches for actual use. Let us wait and watch.
