Are you afraid that someone will take a WhatsApp DP screenshot, then there is a solution?

 

WhatsApp introduced new privacy feature to prevent screenshot of WhatsApp DP. The restriction has come to take screenshots on other people's profiles. The feature is introduced keeping users' privacy in mind. This feature is currently available on Android. Hopefully this feature will come to iPhone soon.

It is hinted that WhatsApp will soon provide the option to turn off the feature. If you try to take a screenshot while the feature is on, it will show 'Can't take a screenshot due to app restriction'. Facebook already has this feature. No one can take screenshots of locked profile pictures on Facebook.
