Facebook announced that the WhatsApp messenger will stop working on some older operating systems starting January 1, 2021. This will affect two systems: iOS 8 and Android 4.0.3, as well as older versions of these “axes”.
But you shouldn’t be scared much. According to April statistics published by Google, only 0.6% of all Android users are sitting on this version of Android and older. The percentage of WhatsApp users among them, I believe, is even lower. Version 4.0.3 is part of Android 4.0 Ice Cream Sandwich and was shown in 2011.
Among iOS users, the problem will definitely affect everyone who is still on the iPhone 4. It was released in 2010 and was updated until 2014, receiving iOS 7.1.2. iOS 8 was introduced in 2014.
Facebook recommends that all users who are currently unable to switch to new devices, make a backup copy of all correspondence and only then activate them on a new smartphone.
