WhatsApp says in a blog post that users on these particular platforms will not be able to create new accounts, nor re-verify existing accounts once the company ends support.
WhatsApp had earlier announced it will stop support for many of these older platforms. End of support does not mean a user will lose access to their WhatsApp account.
WhatsApp says users can continue using the app on their phone, but should not expect any future security updates or new features.
While Windows 8 will be axed down once 2018 begins; WhatsApp will continue support for Windows 8.1 version and higher devices, even though Microsoft itself has admitted that Windows Mobile is dead.
To recall, WhatsApp had extended support for both platforms in June this year. At the time, WhatsApp had also revealed that the app will stop working for phones running Nokia S40 will be stopped from December 31, 2018.
The app will stop working on phones running Android 2.3.7 and older (Gingerbread) will be stopped from February 1, 2020. The messaging app became unavailable on Nokia phones running Symbian S60, from June 30, 2017.
In BlackBerry’s case, the company has itself confirmed it will no longer be manufacturing or launching new smartphones, and the BlackBerry 10 and BlackBerry OS have been abandoned.
