Facebook Lite is a smaller version of the social networking app made for developing countries and markets.

Facebook Lite

After first being tested in a few countries in January, Facebook is now officially launching a new and smaller Android version of its social networking app called Facebook Lite. The app is designed specifically for use in countries where the wireless networks are slow and thus not able to handle all of the features in the regular Android version of the app. Facebook states:

Facebook Lite was built for these situations, giving people a reliable Facebook experience when bandwidth is at a minimum.Facebook Lite is less than 1MB so it is fast to install and quick to load. It includes Facebook's core experiences like News Feed, status updates, photos, notifications and more.

The rollout of Facebook Lite will begin first in a number of countries in Asia, and later it will become available in parts of Latin America, Africa and Europe.
