How to Activate Facebook Dark Mode (2021)

Here are the steps to enable Facebook‘s dark mode. In this case, I’m using a PC, Android, and iPhone. Let’s get started.


Log on to Facebook.

Click on the “Reverse triangle” at the top right.

Hit Display & accessibility.

You can see the following in the “Dark mode” section:

  • Off – Disables Facebook’s dark mode.
  • On – Turn on Facebook’s dark mode.

Pick the one you prefer.

Android or iPhone

Open the Facebook app.

Tap the three horizontal lines at the bottom (if you’re using an iPhone) or at the top (if you’re using an Android).

Hit Settings & Privacy.

You can now see Dark Mode. Hit it.

The following three options are available:

  • On – Enable dark mode.
  • Off – Disable dark mode.
  • System (if you’re on an iPhone) or Use system settings (if you’re on an Android) – The app will also be in dark mode if the device is in dark mode. It will not be in dark mode if the device is not in dark mode.

Select the one you prefer.

That’s all.
