Older Android and iPhone devices will no longer support the latest version of the app, forcing owners to either update their mobile operating system or buy a new smartphone, the Independent reported.
The UK based newspaper reported that any iPhone not running iOS 9 or newer, or any phone not running at least Android 4.0.3 also known as Ice Cream Sandwich – will no longer be able to open or operate the Facebook owned app.
This means all iPhone models up to the iPhone 4 will be unable to support WhatsApp, as these phones are not capable of updating to iOS 9.
