Many Facebook Messenger users on Android are finding out that they can now enable Dark Mode in the Messenger app by just sending an emoji in their chat list. Facebook has been teasing the implementation of dark mode for some time, and it was one of the most wanted feature changes for the app. Dark mode has become more popular because people are rightly concerned about how the blue light from the screen affects their brains. Some people also say that the dark mode may be easier on the eyes.
Instead of making a full announcement and immediately deploying this feature, Facebook decided to hide the new feature in the app for users who sent the crescent smiley to one of their friends. As expected, the news quickly came out about an Easter egg, until it was reported to the media.
