WhatsApp will stop working on older iPhones and Android smartphones

Come January 1st 2021, WhatsApp will stop working on older iPhones and a lot of Android smartphones. Few may lose access altogether, while others may not be able to use new features on the messaging platform.

We advise you to update your devices to the higher versions of their operating system to keep using Whatsapp.

If you can’t update your devices, you will either have to buy a new smartphone or look for alternatives to WhatsApp.
