The Sony D6503 ‘Sirius’ leaks continue and this time we have the first video of the device in action. What you see below is not a hardware tour of the device, but a quick look at Sony’s Android KitKat skin. You’ll see the new unlock screen effect at the very start of the video. There is also a look at the Walkman lock screen and how you can progress through a particular song. Other features in the video are Xperia Themes, quick-starting the camera from the lock screen and a quick look at Sony’s camera apps. Check out the video below.
