The latest version of Windows Camera (5.38.2004) on the Windows 10 Mobile now comes with face-tracking technology. This now enables it to recognize your face when you’re using the front camera.
For those that are unaware, face-tracking technology assists the camera to automatically adjust focus even if the photographer’s hands are unstable or is in motion. This feature was notably absent from Windows Phone 8.1
In addition, this latest build features an updated camera icon which is aimed at making the app more recognizable.
