For the Back and Home buttons I use "Back Button Anywhere". It works pretty good.I have this working great on my EX-5S. I’m using Nova launcher (free version) and Aurora Store as a Play Store replacement for downloading/managing Apps. The only part I’ve not managed to get working is the home and menu soft buttons. These have been disabled by Echelon I believe and the commonly suggested fix for this (which uses Nova launcher) doesn’t work for me since it relies on an activity being installed on the device which I think Echelon have also removed!
Has anyone else figured out a workaround for this?
