• Caller ID: businesses that aren't in your contacts are now named — while it rings, during the call, when you call out, and in Recents.
• Warnings about numbers other people have reported, and a question after the call so you can flag a nuisance.
• Get your own number off the list by confirming it over SMS.
• The call notification now looks like a real call and stays at the top.
• Tap the app icon during a call to go back to it.
