Introduced last week, Home is the new interface the social network has designed for Android smartphones. Instead of applications or widgets, Home puts Facebook pictures and posts front and center.

The problem with Home is that it offers both more and less of Facebook than many people are likely to want. Although it puts Facebook at the center of your smartphone experience, it offers only a limited slice of the social-networking site and little ability to customize your experience.

I’ve been testing Home for the past several days on an HTC First smartphone, which is — as the name suggests — the first device to come with the software preinstalled. Consumers were able to buy the First or download Home to a handful of other Android devices as of Friday.
