If you're a big fan of Paranoid Android's Chat Heads-inspired Halo feature, I've got some unfortunate news for you. Yesterday a known member of the Paranoid Android development team, "PirateGhost," posted a reply to an XDA thread waiting on Halo in a new PA beta build.
You are going to be waiting a loooooooooooong time. Halo is dead.
The story was picked up by the folks at the Android subreddit, where reactions ranged from dismissive to inconsolable.
