In a blog post, the Facebook-owned app said it will be phasing out compatibility with older phones.
"**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,**" Whatsapp wrote on its website.
The company proceeded to say technology has changed dramatically since its inception, which led to its decision to drop support for ageing mobile platforms

**iPhone:** The app will stop working on **iPhone 3GS** at the end of this year. It will also cease to function any iPhone running **iOS 6,** so any phone which hasn't been updated to a later operating system will lose WhatsApp.
**Android:** WhatsApp will cease to function on any Android tablet or phone running **Android 2.1 or 2.2.** This covers devices released between May 2010 and November 2011 from many different manufacturers.
**Windows:** Anyone still using Windows Phone 7 will not be able to use WhatsApp anymore.
WhatsApp was planning to drop support for BlackBerry OS, BlackBerry 10, Nokia S40 and Nokia Symbian S60 at the same time as the above operating systems, but it had a change of heart
**The support period for these devices has been extended to June 2017.**
