The HTC First runs Android 4.1.2 "Jelly Bean" and Facebook Home, a new interface layer developed by Facebook that heavily integrates with the service.[9] Facebook Home consists of a home screen and lock screen replacement known as Cover Feed (which aggregates content posted by friends on Facebook along with notifications from other apps), the ability to message users (via either Facebook or SMS) from any app using the "Chat Heads" overlay, and an overall experience that is oriented towards social interaction.[10] The HTC First was also the first smartphone to include the recently acquired Instagram as a pre-loaded app.
