“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,” a spokesperson for WhatsApp said.

The company has set a deadline of the end of 2016 for several older services that will no longer be supported.

      iPhone users:

WhatsApp will soon stop working on any iPhone 3GS – which is the second generation handset that was released in 2009.

Whaatsapp will also stop being supported on any device running iOS 6. That means, potentially, any iPhone 4, 4S, or 5 that hasn’t been updated to the newest version of the operating system – iOS 9.3.

It also affects any first, second, third or fourth generation iPad that hasn’t been updated.

Android phones

Any phones or tablets running Android 2.1 or 2.2 won’t be supported after the end of the year. This covers devices released between May 2010 and November 2011 from many different manufacturers.

Android’s latest version is 7.0 – known as “Nougat” – although it’s still not widely available.

     Windows Phones

Windows Phone 7 was released worldwide in October 2010 and Microsoft itself stopped supporting the system in 2014. So it’s not really a surprise to see WhatsApp dropping support for it as well.

If you’re still using Windows 7 we’d recommend updating it as soon as possible.

BlackBerry and Nokia phones

For BlackBerry OS, BlackBerry 10, Nokia S40 and Nokia Symbian S60, Whaatsapp is extending its support period for these devices into 2017. These devices will be supported until June 30, 2017.

“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.
