Facebook Lite, which is a version of Facebook made for developing countries designs to run on 2G networks, is rollout to more countries, including developed countries as well, per Reuters. Much like the Messenger Lite, the idea behind it is that people with older Android devices or slower internet connection are able to still access Facebook with a stripped-down version.
Facebook Lite first launch in 2015 as a test in Bangladesh, Nepal, Nigeria, South Africa, Sudan, Sri Lanka, Vietnam, and Zimbabwe, but is now available in over 100 countries. It's only 252 kilobytes, and is based on the Snaptu version of Facebook that runs on feature phones, but comes with functionality like push notifications and camera integration.
In the rollout, the app will become available in countries including the US, Canada, Australia, UK, France, Germany, Ireland, and New Zealand.
Beginning Friday, Facebook Lite will be available for downloads in all appropriate markets.
