Google's desire to integrate social features into its mobile OS will soon see it use Google+ profile photos to identify Android callers. The new feature comes as an update to the new caller ID service in Android 4.4 KitKat, allowing the company to automatically match phone numbers from incoming and outgoing calls with names and profile photos associated with a registered account. Google staffer Attila Bodis notes that the feature will be enabled in "early 2014" but can only display names and profile photos if the user has verified their phone number and has discovery switched on. While the idea is to bring a sense of familiarity to phone calls, not everyone will see the merit of sending a headshot to people they call -- so Google is offering a way to opt out. Simply head on over to this link, untick the checkbox and all of your Android-toting friends will no longer be able to see your beautiful face (unless, of course, they add it themselves).
