WhatsApp is one of those Android apps which have a pretty active beta channel. The app keeps receiving a new beta update every now and then which also bring some major changes for most of the time. This time, WhatsApp beta has received a new update which brings the ability to pin chats so that you don't have look for them manually.
WhatsApp now lets you pin up to any three chats at top of the Chats interface. You can pin any chat by simply tapping and holding on it and choosing the Pin option from the list. Once you have pinned a chat, it will remain on the top regardless of the last time it received a message. All other unpinned chats will be ordered as per the last message received by them and you can pin/unpin any chat at any point in time.
This new chat pinning feature is said to be available with WhatsApp beta 2.17.162 and 2.17.163. So if you are a regular WhatsApp user who also happens to be talking with a number of people, you can now mark pin those chats which are more important for you.
You can get the latest WhatsApp beta using the link given below. If you are not a beta member, you can become one by following the same link or simply download the APK from APKMirror.
