San Francisco, Dec 31 (IANS): Facebook-owned WhatsApp has been dropping support for dated devices and operating systems (OS) from time to time and now it is ending support for iOS 7 and older versions, Android 2.3.7 and Nokia Series 40 (S40).

What this means is that users of Nokia Series 40 device will no longer be able to create new WhatsApp accounts and some features of the app could stop functioning on the device at any time.

"When we started WhatsApp in 2009, people's use of mobile devices looked very different from today. The Apple App Store was only a few months old. About 70 per cent of smartphones sold at the time had operating systems offered by BlackBerry and Nokia.

Mobile operating systems offered by Google, Apple and Microsoft -- which account for 99.5 per cent of sales today -- were on less than 25 per cent of mobile devices sold at the time," it said in a blog post on Sunday.

You will, however, still be able to use WhatsApp on the device though, according to the Dignited.

The Nokia S40 OS was seen in the company's mid-tier devices like Nokia Asha 201, Nokia Asha 205, Nokia Asha 210, Nokia Asha 230, Nokia Asha 500, Nokia Asha 501, Nokia Asha 502, Nokia Asha 503, Nokia 206, Nokia 208, Nokia 301, Nokia 515.

Earlier, WhatsApp had outlined devices and OS that would be cut off from its support room and affixed dates to them accordingly. Nokia S40 would be supported until December 31, 2018, Android versions 2.3.7 and older until February 1, 2020 and iOS 7 and older until February 1, 2020.
