Are you bored of your old stock navigation keys on your Xperia device, well if yes then here is something you can try i.e. customized SuperUser navigation bar softkeys courtesy of XDA user androidfreak70. SuperUser is an app used to main app admin rights permission on rooted devices. If you are not using some modded Xperia themes this SuperUser navigation bar softkeys are pretty cool.
It works great on rooted, deodexed Xperia Z ROM but it should also work on stock KitKat ROM. Back up your systemUI.apk first before using this mod. You need to download the below attached systemUI.apk file and push in system/app folder, set permissions rw- r– r– and reboot. Follow these steps to move app to system/app folder.
