After a long break from XDA I have something very very cool for you:
the new Xperia™ Live wallpaper from Xperia Z3 lollipop
It adds the latest lockscreen effect from Xperia Z3 to all devices with NO ROOT and just looks awesome (Screenshots from Xperia Z 4.4.4 non-rooted)
download it here: ExperienceFlow2LiveWallpaper.apk
please tell me if it works for 4.3, too
btw you may have seen the navbar icons (?)...
Tip: I'm working on a Xperia Lollipop theme to bring to older devices which don't have the honour to get the first update....
