Facebook isn't done trying to replace your Android phone's software just becauseHome fizzled out. Android Police tipsters have spotted the social network testing a dialer app that would not only show more info about who's calling, but stop calls from "commonly blocked numbers." In theory, this would prevent telemarketers and technical support scams from getting through even when you don't recognize their digits. It's not clear if or when this dialer will ever see the light of day -- these kinds of tests happen all the time. If it launches, though, it could be one of the few standalone Facebook apps that you actually want to use.
