Though I’m not seeing it on my own device yet, the option has appeared for several users. It should appear as a toggle right beneath the ‘Settings’ button of the hamburger menu. Facebook Lite, for those who aren’t familiar, is a significantly downsized version of the Facebook App, meant for users with limited data access, though also popular just because it’s less bloated than the normal version. It fits the social network’s most essential features into an app that requires less than 2MB of data to download. For comparison, the standard Facebook app is about 39MB. Once installed, the apps take up about 9MB and 400MB on my device, respectively. Android Police notes the feature appears to have begun appearing in January – it’s a server-side change – but Facebook appears to have ramped up the rollout recently. 91Mobiles also reports Facebook appears to have begun a wide rollout of Dark Mode to the desktop users in India. Hopefully, this all means Dark Mode isn’t too far off for the normal app for the rest of us.
