WhatsApp is finally getting a feature that has been widely available on many other messaging apps: stickers. They will finally be enabled for WhatsApp on Android soon, once it is out of the beta test phase.
In general, the method of sharing the stickers looks quite similar to the other messaging apps. Specifically, all users need to do is select an emoji, and a related sticker will appear for the users. Four reaction categories currently can be seen in beta WhatsApp release: LOL, Love, Sad and Wow.
Users apparently can download more stickers from the in-app store as well. While there are only four stickers in the beta version of WhatsApp, more are expected to be added once this option is live.
WhatsApp will be joining other messaging apps such as Telegram, Line and Facebook Messenger to feature stickers. Right now there is no set date on when the feature will be going online, so you still have to wait before you can spam reaction stickers on your favorite (or most hated) WhatsApp group chats.
