It looks like another big free upgrade is coming to WhatsApp on iPhones and Android phones: the eagle-eyed crew at WABetaInfo have found a new screen sharing feature in the latest WhatsApp beta. The feature doesn't appear to be available to all beta testers but it does seem to be pretty well advanced, so it's likely to turn up in the final version of the app fairly soon.
The new feature adds a new icon to the call control view, and if you tap it you'l lbe asked if you want to start recording or casting with WhatsApp. If you say you do, you can now share your screen: anything you do on your phone will be seen by the other person you're calling.
