WhatsApp will stop working on millions of phones on January 1

The peer-to-peer messaging app WhatsApp will stop working on millions of phones on January 1, leaving many without access to the popular app.

The change will affect older phones and users will need to update their software to avoid being affected by the issue.

According to News18, people who use older versions of the iOS and Android softwares will be affected.

WhatsApp will reportedly stop working for anyone using an iPhone that hasn’t been updated to iOS9 or higher.

For Android users, the app will stop working for those who don’t have Android 4.0.3 or later.

People with iPhone 4 models will not be able to upgrade to newer software. The same will happen to people with Android devices like the Motorola Droid Razr and the Samsung Galaxy S2.

To find out what software you are using and if you need to update before the new year, Apple users should go to their Settings, then “General” and “About”.

Android users can check their settings and then select “About phone”.

WhatsApp will warn users that they need to update their software to continue using the application.

The application is one of the most popular messaging platforms in the world, with more than two billion users.
