Few smartphones will not support WhatsApp from Jan 1

Starting next year, WhatsApp will stop working on millions of older mobile devices globally as the company has withdrawn support for such phones.

The users on Windows Phones will be locked out forever after December 31, said Facebook.

"WhatsApp will stop working on millions of phones in the next couple of months as the company withdraws support for some older mobile platforms.

"From February 1, 2020, any iPhone running iOS 8 or older will no longer be supported, along with any Android device running version 2.3.7 or older," Facebook said.

Users of these operating systems are already unable to create new WhatsApp accounts or re-verify existing accounts.

"Furthermore, WhatsApp is withdrawing support for all Windows phones from December 31, 2019 -- the same month that Microsoft ends support of its Windows 10 Mobile OS," the social networking platform added.
