Sometime after Android received the features in July for its beta app, WhatsApp for Android and iOS are both officially getting the callback and voicemail update. With WhatsApp version 2.16.229 on Android and 2.16.8 on iOS, you can now leave a voice message when a contact doesn’t pick up a call. Once the call is disconnected, it pops up three options asking if you want to “Cancel”, “Call Back”, or leave a “Voice Message”. Hold down the voice message button to record and release to save and send once you’re done. In addition the “secret” font has also made it into the WhatsApp update.
