Facebook Messenger dark mode

The love of dark mode options in apps and operating systems shows no sign of waning. While a large number of big-names have added dark modes, there are still plenty that need to jump on the bandwagon. One app that has held out is Facebook Messenger, but there is secret dark mode option that you can enable.

Probes into the Facebook Messenger app had already revealed that Facebook was working on darker hues, and it even rolled out to small number of users in the latter part of last year -- but not everyone. Now you can use a little trick to access dark mode in the Android and iOS versions of Messenger for yourself.

What you you need to do is send a crescent moon emoji to one of your contacts in a message. After you hit the send button, you'll be treated to a little moony animation to indicate that you have unlocked an Easter egg.

Now if you head to Settings, you'll find a new Dark mode option which you enable.
