WhatsApp users who use the app on an iPhone 4 or older and outdated Android handsets will be unable to use the app properly as of January 1, 2021.
The Facebook-owned messaging platform is stopping support for iOS 9, the operating software released by Apple in 2015.
Non-Apple users with an older device will also be affected if their device still runs Android 4.0.3.
iOS 9 was the last software update the iPhone 4 could receive, with later models able to upgrade to newer versions. Apple released iOS 14 in September 2020.
Models like the 4S, 5, 5S, 5C, 6 and 6S can all be updated in order to keep WhatsApp functioning on the phone.
Android 4.0.3 was released in 2011 and replaced the following year.
The move to stop support for older devices is a regular tactic of app developers which frees up resources to be focused on improving the product for the majority of users who have more modern handsets.
However, WhatsApp is one of the world’s most popular apps, with 2 billion users.
WhatsApp is also popular around the world, in places where cheap and older smartphones are still commonplace.
Users concerned about losing access to their WhatsApp should check their phone’s settings to find out if they run either iOS 9 or Android 4.0.3.
For phones which can not be updated to run more recent software the app will stop working properly as 2021 dawns.
These users will need to either export their chars and save their messages or upgrade their phone to avoid losing access to their chats and their contents.
