Whatsapp is set to stop working on some mobile phones from January 1.
The popular messaging app will no longer be supported by certain smartphones on New Year's Eve.
WhatsApp will not be available on devices that are not running iOS 9 or Android 4.0.3 operating systems starting January 2021 - reports Birmingham Live.
This primarily include the iPhone 4, and all earlier models.
If you have iPhones iPhone 4S, iPhone 5, iPhone 5S, iPhone 5C, iPhone 6, and iPhone 6S, all you have to do to get WhatsApp is to update your software to iOS 9.
If you have one of the affected handsets and don't want to lose your chats, you're advised to back up your WhatsApp messages so they won't be lost.
To do this, open the chat you want to save and click on 'Group Info'.
You'll then need to click 'Export Chat' - and you'll be given the option to download the chat with our without media.
The news has emerged just a month after it was revealed a new service was coming to the app.

WhatsApp is introducing a "disappearing messages" option that will erase chats from the phone of both the sender and recipient after seven days.
The Facebook-owned app, which has two billion users worldwide, said the setting would help keep chats private.
In a blog, the company said messages could be set to expire after seven days to offer "peace of mind that conversations aren't permanent, while remaining practical so you don't forget what you were chatting about".
