So I've been cropping videos, turning them into soundless videos to be used as wallpaper for lockscreen, the issue is I have too many to choose from :p so is there anyways the wallpapers can be changed upon tapping the power button?

Other questions: Is there any way the 15 seconds limit can be pushed? And how can the duration before black out be increased?
