WhatsApp has announced it will no longer support a range of older operating platforms by the end of the year. The messaging app said it will be phasing out support for older Windows, Android and Apple models by January, and Blackberry and Nokia by mid-2017.


The older smartphone platforms can no longer keep up with the latest features being rolled out for the app, claims blog post by the Facebook-owned app. 

WhatsApp made the announcement as it celebrated its seventh anniversary, after first launching the popular messaging platform in 2009.

The app, which is now used by more than one billion people worldwide, was launched in the early days of Apple's App Store, when seven out of ten had operating systems offered by Blackberry and Nokia.

However, today's smartphone market is dominated by Google, Apple and Microsoft, with almost all newer models running on these platforms.

The firm wrote: 'As we look ahead to our next seven years, we want to focus our efforts on the mobile platforms the vast majority of people use.'

The full list of platforms being left behind at the end of the year includes: Android 2.1 and Android 2.2; Windows Phone 7 and iPhone 3GS/iOS 6.

And by June 2017, WhatApp will no longer be available for BlackBerry, including BlackBerry 10; Nokia S40; and Nokia Symbian S60.

The Nokia Symbian open source operating system, launched in 2007, is the oldest OS capable of running the app.

WhatsApp explained: 'While these mobile devices have been an important part of our story, they don't offer the kind of capabilities we need to expand our app's features in the future.'

Users still on one of the listed platforms are advised to upgrade to newer Android, iPhone or Windows phone platforms.

The firm added: 'This was a tough decision for us to make, but the right one in order to give people better ways to keep in touch with friends, family, and loved ones using WhatsApp.'
