The above video is in German, but even if you don't understand the language it might be worth checking out. The All New (2014) HTC One is on display in another leaked preview video. The most notable thing shown off in the video is some of the camera functionality. The video shows off the camera's dynamic post-snapshot focusing feature. This is one of the main advantages of the dual-camera in the device.
The phone can quickly adjust focus between to different people in the same scene. A few other features of the phone are demoed as well, including the newer versions of Zoe and Blinkfeed. Enjoy!
