As reported by Metro, WhatsApp, the most popular messaging app in the world, is about to stop working on thousands of phones. The app is set to stop support for older phones around the world on November 1, 2021. It will cease to function on up to 43 different smartphone models as it shifts the requirements for the Android and iOS operating systems.
In the FAQ section on its website, WhatsApp says people should use phones running Android version OS 4.1 or iPhones running iOS 10 and newer. If you haven’t updated your system software recently, then you may well escape having to upgrade. But a few select devices – of which there could be thousands still being used – will lose security and feature updates.
