Facebook says it is testing a lightweight version of its mobile app for mobile phones with poor-quality internet connections in emerging markets.
A spokesman told AFP in an email that the "Facebook Lite" Android app is designed "for people on 2G (second-generation) connections or in areas of limited internet accessibility".
The move expands Facebook's efforts to grow the world's biggest social network, which already has more than a billion users.
Most of Facebook's growth is coming from emerging markets, but many people lack the phones or computers needed for the full-featured app.
The "lite" version can allow users with low-cost Android handsets to quickly load Facebook feeds and photos.
