WhatsApp will end its support for several smartphone platforms by the end of this year. The Facebook-owned company has confirmed this via its official blog post. The messaging service will pull the plug on mobile platforms like BlackBerry OS, BlackBerry 10, Windows Phone 8.0 and older on December 31, 2017. This means that users using mobile phones running any one of these platforms will not be able to use WhatsApp after this year.

The WhatsApp blog post with end-of-life dates clearly mentions that users of BlackBerry OS, BlackBerry 10, and Windows Phone 8.0 and older operating systems will not be able to use the app after December 31, 2017 – less than a week from now.

Ending support for Blackberry and Windows Phone has seen no further extensions and will come into place on the mentioned date. If your phone has any of the two specified operating systems, you should consider upgrading to a newer phone in order to access WhatsApp properly. WhatsApp updates for other OS versions like Windows Phone 7, Android 2.1, Android 2.2, and iOS 6 were stopped in 2016.
