According to a recent report from WABetaInfo, the latest update for WhatsApp beta for Android brings a new 'Media Visibility' feature which will allow users to hide their WhatsApp media from the gallery outside WhatsApp.
The update also brings a new contact shortcut, which is similar to the one found on the iOS version of the app. It's worth noting that the new Media Visibility feature might not be available on all devices and even if it is available, it might not work. We tried turning it off on one of our devices, but the WhatsApp media was still visible in the phone's gallery.
