WhatsApp had already made an announcement that their app will not work on older devices or devices running outdated software. From 2017 onwards WhatsApp will not work on smartphones running Android 2.2, Windows Phone 7 and iOS 6.
WhatsApp Video calling will be rolled out soon, in phased manner; users might get the update within few weeks. Unfortunately there are already malicious links popping up on WhatsApps inviting users to download video calling feature on WhatsApp.
There was news about Whatsapp implementing video calls, in fact some Whatsapp beta users actually were able to use the video call feature – it was later removed. Well for now it seems Whatsapp has started rolling video call support on Whatsapp beta.
Good news for WhatsApp users, the company has announced that it will no longer charge subscription fee. WhatsApp will be free, there will be no charges and the company will not be using any third party ads to earn revenue.
