Be careful, if you use a smartphone that is over five years old.WhatsApp will stop supporting certain versions of Android and iOS from November 1.This announcement concerns a tiny part of service users.

As the company explains on its site, the messaging will no longer work properly on the terminals equipped with the versions prior to Android 4.1 and iOS 10, operating systems for Android mobiles and iPhone, launched respectively eight and five years ago.

Concretely, from Monday, smartphones using iOS 9 and Android 4.0.4 can no longer have access to WhatsApp updates.In theory, they will be able to continue to use it under an old version but certain features will be gradually unavailable until the application continues to operate.

In total, around forty smartphones that have been marketed with a version prior to iOS 10 and Android 4.1 are affected by this change at Apple, Samsung, Huawei or LG.

The owners of some of these devices can install a more recent version of the operating system to continue using WhatsApp.At Apple, for example, the iPhone 6s and the first generation iPhone were launched under iOS 9 but they are compatible with the update to iOS 15 launched this fall and are therefore always supported by WhatsApp, respectively five and sixyears after their marketing.

On Android, on the other hand, most of these devices are no longer supported by Google, since the end of the support of Android Jelly Bean this summer, and their use is therefore no longer recommended today.
