There’s this fact that WhatsApp has end to end encryption and it lets you share files pretty easily that make it a popular app. If you have one too many active chat threads, you might have trouble keeping track of the important ones.
That’s why WhatsApp has added a new pin feature. You can pin a chat in WhatsApp to the top of the Chat tab and it won’t get lost among the other message threads.
This feature was added via an app update so make sure you’re running the latest version of WhatsApp. The update is already available worldwide so there’s nothing to wait for. All you need to do is update the app.
Open WhatsApp and go to the Chat tab. Swipe right on the chat thread you want to pin. Don’t swipe all the way to the right edge of the screen. This will mark messages in the thread as read or unread. Swipe right until you see two buttons; Read, and Pin. Tap the Pin button to pin a chat in WhatsApp.
