Still using your 'old school' BlackBerry? WhatsApp won't work in 2018
From January 2018, WhatsApp will stop working for certain phone operating systems.
After December 31, 2017, any BlackBerry device running on BlackBerry OS or BlackBerry 10 will no longer be able to use the messaging service. BlackBerry shifted to Android this year, but older handsets still use its own in-house software.
Additionally, any phone using Microsoft's Windows 8.0 (or older) OS will not be supported. Whatsapp also stopped being operational on the Nokia Symbian S60 after June 30 of this year.
The messaging app giant initially made the announcement earlier this year, explaining that it was moving forward with the iOS and Android platforms.
"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 company said in a blog post.
"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.”
Even though it has over a billion users, many of whom have older phones, changes in technology mean it has to phase out compatibility to keep security up to date.
It added that because they will no longer actively develop for these platforms, some features may stop functioning at any time.
