A few months ago, Ubuntu Touch was unveiled. It had quite a vibrant and a very different UI for the smartphones. Along with a different UI, the lockscreen of the Ubuntu Touch also caught the eyes of some observers. This lockscreen can be used on Android smartphones too.
XDA Senior Member Rotary Heart has been able to create an Ubuntu Touch style lockscreen app for Android devices – Ubuntu Lockscreen. The developer has retained almost all the main functionality of the Ubuntu Touch lockscreen. If you want to unlock the device, you have to simply slide from the right edge to the left.
