WhatsApp is Facebook’s most popular instant messaging platform and possibly the most popular chat app in the world. It works on phones, tablets, and PCs, and features end-to-end encryption support. It offers several handy features that make it a must-have app on your phone, regardless of the operating system, including cross-platform support, which allows iPhone users to chat with their Android friends who do not have access to iMessage.
Unfortunately, some devices will no longer be able to run the app starting next year. Come Friday, January 1st, WhatsApp will stop working on some smartphones, including certain Android and iPhone devices.
