O Whatsapp offers the option to upload photos that can only be viewed once for quite some time. Still, the messaging app doesn’t have a solution to prevent recipients from taking a screenshot of the temporary images. Fortunately, the messenger team is developing a block to prevent single-view media screenshots.
The first reports of the solution appeared in August. In season, Mark Zuckerberg announced that the messenger would now block screenshots of single-view messages. The CEO of Meta, however, did not say when the news would arrive and also did not offer any extra explanation about the change.
The new details came to light this Monday (3). According to the portal, the feature appeared to some users with WhatsApp Beta for Android, version 2.22.22.3, on mobile. The website also explained how the change impacts app usage.

WhatsApp will have a lock for prints in single view
The new tool intends to offer more privacy to users. This means that, when submit a nude an image that can only be viewed once, the person who received the media is unable to take a screenshot. Instead, the app issues the warning “unable to take screenshot due to security policy”.
The lock also prevents screen recording if it is a video. However, it is important to note that, despite the block, WhatsApp does not inform if someone tried to take a screenshot. In addition, there are ways to circumvent even without third-party apps, such as using another cell phone to take a photo of the smartphone that received the content.
In other words, it is a complement beyond necessary. After all, if you send sensitive content, blocking ensures even more security and privacy for users. But it is necessary to reinforce: despite the lock, this does not mean that the resource is inviolable – therefore, caution will always be necessary.
It is not yet known when the feature will come to stable versions of WhatsApp.
