WhatsApp is the world's most popular chat app, but it can be daunting if you're new. Here's our guide on how to use WhatsApp!

The hugely popular instant messaging platform WhatsApp is testing a new change to help make it quicker and easier to add people to group chats.

WhatsApp has silently rolled out the ability to open chats and text new and unknown numbers, without needing to add them to your contacts.

WhatsApp introduces an in-app dialer that lets you call unsaved contacts without the hassle of saving their numbers.

If you get a new phone number, it's simple for someone else to take over your Whatsapp account and assume your identity, accidentally or on purpose.
