Which mobile phone platforms won't be supported by WhatsApp in 2017?

WhatsApp is declared as the world's largest cross-platform instant messaging application. Why wouldn't it be when there are more than one billion people using the app to communicate with their friends, family and colleagues.

But there will be some disappointed faces come next year when the Facebook-owned messaging app will finally stop supporting some mobile platforms. Users of BlackBerry, Nokia S40, Nokia Symbian S60 will no longer be supported by WhatsApp after June 30, 2017. This is an extension that the company is offering to the affected users after it had announced that it would end support to the aforementioned operating systems by end of 2016.

"We will soon be ending support for certain devices. On June 30, 2017, we will no longer support the following platforms: BlackBerry OS and BlackBerry 10, Nokia S40, and Nokia Symbian S60," the company's statement reads on the updated support page.

In addition to that, WhatsApp will also end support for dated Android, Windows Phone 7 and iOS version. The company urges users running Android 2.1 and Android 2.2 to upgrade to newer Android versions, iOS 6 or iPhone 3GS users to upgrade to iOS 7 or latest iPhones and Windows Phone 7 users to make the jump to Windows Phone 8 or above versions.

"These platforms don't offer the kind of capabilities we need to expand our app's features in the future," WhatsApp said.

Even if the users choose to upgrade their aging operating systems for newer versions, there is no option to transfer the chat history. However, the app allows its users to email the chat history using all platforms, a feature which can come in handy at this hour of need.

WhatsApp is constantly upgrading its services to meet the growing requirement of its massive user base. The latest feature to be added to the app is video calling, which makes WhatsApp a complete communication app as it already offers voice calls and messages.
