WhatsApp is ending support for numerous older Android and iOS operating systems, impacting tens of millions of smartphone users. The messaging app has published updated system requirements on its website, notifying users of the impending change. Devices running outdated software will no longer be able to utilize the platform. This move aims to improve security and enhance the app’s features, which are better supported by newer operating systems. Users with affected devices are urged to update their operating system where possible, or risk losing access to WhatsApp. The specific versions being discontinued were not detailed in the announcement, but the change will affect a significant number of users globally. Failure to update will result in the app becoming unusable on those devices.
