Facebook Inc rolled out a new Android app for its social media service that uses less data and runs faster in regions with spotty connections. The app, called Facebook Lite, is available in countries across Asia and will soon make its way to parts of Latin America, Africa and Europe, Vijay Shankar, product manager for Facebook Lite, said in an interview. In many of those countries, people still use 2G networks, which are much slower and have less power than the 4G networks in many developed nations.
