Facebook has rolled out a dark interface for Messengers app in its new update. Turning on dark mode in Messenger only takes a couple of taps:
Open Facebook Messenger and tap on your profile icon on the top of the left corner.
You will see the Dark Mode toggle under your profile photo.
Once you have turned on Dark Mode, all of the white backgrounds are instantly replaced with black.
However, if your Messenger does not have Dark Mode by default yet, you can wait until Facebook fully rolls out the newest feature to everyone.
Or, you can unlock it as a hidden feature. It will be fun.
Open the Facebook Messenger.
Go to a chat thread (any person).
Once you have sent the moon emoji, tap on it in the thread.
A prompt will appear. Tap on it and activate the Dark Mode in the setting.
The Dark Mode will provide lower brightness while maintaining contrast and vibrancy. It also cuts down the glare from your phone for use in low light situations, so you can use the Messenger features you love no matter when or where you are. Not only it is easier for your eyes, but it also saves battery life.
