When Microsoft announced Windows Phone 8.1 back at its BUILD conference, one of the features that was mentioned included dynamic lockscreens, which would allow developers to make custom lockscreens. Unfortunately, this feature was not included on the test build that was released to developers.
Now, a new video has surfaced that shows one example of customizable lockscreens. The lockscreen has fullscreen album art and music player controls that allow complete control over the playback from the lockscreen.
You can check it out in the video below.
