WhatsApp said it will "remove support" for the phones because the newer version can not be installed on them. Also, the company confirmed to end support for Nokia S40 devices on December 31, 2018, a year from now, and Android versions 2.3.7 and older devices on February 1, 2020.
The app is in principle similar to Continue on PC which lets you transfer web links and pictures from their Android or iOS device to their Windows 10 PC using Microsoft's apps like Cortana, Microsoft Edge, and Microsoft Launcher (Android only). The company has announced that its mobile messaging app will stop working on phones having Blackberry operating system and Windows 8.0 or older Microsoft operating systems in phones.
In the post, WhatsApp tried to explain how things have changed since the app was released in 2009.
Older mobile platforms' enthusiasts are in for a change in 2018.
WhatsApp listed the devices that no longer support the device.
For most WhatsApp users, pulling support for older operating system (OS) versions will not really be noticeable.
The company said: "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".
If you are still using Windows Phone 8 or BlackBerry device, WhatsApp may stop working on your phone at any time.
And any people with phones running on Android 2.1 and Android 2.2, BlackBerry OS or iOS 6 will either want to rethink their handset altogether or simply update their operational system.
The messaging app is now one of the most popular chatting apps out there.
