The popular messaging app WhatsApp will stop working on millions of smartphones in a few weeks.
Those affected won’t be able to access messages, photos and videos – unless you act now by upgrading to the latest operating systems or buying a new phone.
WhatsApp has warned Android and Apple users that they need to urgently update their software, or risk not being able to use the app.
Every year operating systems change and develop, meaning it will no longer be able to be used by phones running older versions.
This time round 53 smartphones will be affected by the update, which will kick in from November 1.
Smartphones models with Android 4.0.4 or earlier installed will become incompatible with WhatsApp, as well as iPhones with iOS 9 or earlier installed.
