Whatsapp Beta for Android in its latest update which makes the app version to 2.16.189 brings some new features like Voicemail and call back feature available directly in the after-call menu. Moreover Whatsapp for iOS gets a new font.
If the person you are calling declines the call, or does not pick it up, you (the caller) will see a new screen. Regardless of whether the call has been declined or ignored/ missed, the caller will see the same message – ‘Call declined’ – alongside three options – Cancel, Call back, Record voice message.
Whatsapp normal users will also get the features very soon in future. If you want to use these features then you have to install the Whatsapp beta app from Play Store. Kindly tell us your experiences after using these features via comments.
