How to pin a contact on top in whatsapp

Here's how to pin chats on WhatsApp:

1. For Android users, simply long-press on the chat you want to pin and once you do that, a pin icon emerges on the top bar of the app. 

2. Tap on it and the chat will be pinned and placed right on top of all other chats regardless of the messages received on other non-pinned chats.
