According to a report published yesterday, the latest version of Windows camera on the Windows 10 mobile will now have face-tracking feature for clicking a selfie. It will allow to recognize your face and then focus it.
If you are still not familiar with face-tracking technology, it helps the camera to automatically adjust focus even if your hands are not steady, or he or she is moving around. This feature is important because the feature is not present in Windows Phone 8.1. In addition, the latest build also features an updated app icon which helps apparently in making the app more recognizable.
