I have a Galaxy S4 not rooted using Jelly Bean. I tried using Helium to back up app data numerous times, but it never works. Almost every time the GUI crashes within 3 seconds of the backup starting. The notification panel shows Helium is still running. It continues for 1-2 more apps then freezes. On the rare occasions the GUI doesn't crash right away, the backup continues until about ⅔ complete and then it will freeze. Either way the carbon folder on the SD card is empty.

I did the crash report many times. Now it has been almost a year without an app data backup. It's past time to give up and find another solution.
