WhatsApp will completely stop working on all Windows-supported phones from 31st December 2019. It will also not work on a number of Android and iOS phones from 1st February 2020.
For the following operating systems, you can no longer create new accounts, nor reverify existing accounts. However, you’ll be able to continue using WhatsApp on:
- Android versions 2.3.7 and older until February 1, 2020
- iOS 8 and older until February 1, 2020
You’ll no longer be able to use all Windows Phone operating systems after December 31, 2019, and WhatsApp might not be available in the Microsoft Store after July 1, 2019.
Because they no longer actively develop for these operating systems, some features might stop functioning at any time.
