My app icon changer used to work. Now when I choose the new icon it doesn't apply it. Also when I try to add a new one it lets me pick my picture and customize the size. But after that it stays in the gallery and if I back up it gives me an error. "Unfortunately, home has stopped." I don't know if it was an app I installed, disabled or a process I disabled. Please let me know if this happens to you too. The app icon changer instructions are on page 42 in pdf the manual.
