These are some of the major updates we’ve been waiting for from WhatsApp IM for a very long time which could be worrisome to Snapchat despite the facts that they declined Facebook offer of $3 billion acquisition offer in 2013. 
A lot of features have been introduced to WhatsApp which includes:-
>>Front Facing Flash and One Finger Video Zoom: When taking a selfie within the IM, the screen will light up white to brighten your environment.
Even though you are in the dark, you’ll be able to take a selfie within WhatsApp messenger.
And when you’re holding the record button to capture a video, you just need to slide your finger up and down to zoom. These are amazing features.
>>You Can Now Write Text and Draw on Images:-
When you take a photo with the WhatsApp camera, you will be able to crop the image, edit the image, type text on the image, and even annotate and draw on top of it.
>>Bigger Emoji: Single emojis in messages used to appear the same way as all emojis (see the laughing face with tears in the left screenshot below).
But in 2.16.256, bigger emojis were implemented so that these single ones would appear a little larger (see the same emoji in the middle screenshot).
>> You’ll now be able to send multiple chats at once while sharing or forwarding messages. The frequent contacts will appear on top while forwarding or sharing messages.
All these features are live in the latest WhatsApp betas.
