WhatsApp will stop working on all phones running Microsoft's Windows Phone or Windows Mobile software from Tuesday 31 December.
Windows Phone operating system was launched in October 2010 and then succeeded by Windows 10 Mobile in 2015. Users of these Microsoft operating systems have not been able to create new WhatsApp accounts since earlier this year. Microsoft already announced plans to finally kill off its phone software and urged customers to switch to an iPhone or Android phone in January. In 2020, WhatsApp will remove support for some older Apple and Android devices, too. Android versions 2.3.7 and older, iPhone iOS 7 and older are the platforms on which WhatsApp will not work after February 1, 2020.
According to Apple only 7 per cent of devices are running a version of its mobile operating system older than iOS 12 - which was released in 2018. The Facebook-owned messenger service will continue to provide support for devices running Android 4.0.3 onwards and iPhones running iOS 9 and onwards. Despite the lack of success with Windows Phone, Microsoft revealed in October a new foldable device known as the Surface Duo - though it's expected to run on Android instead of a Microsoft operating system.
