I've noticed in Google Analytics that there is still a crash bug in Auto Respond.
From what I can tell, the crash seems to happen when moving from the settings menu, into the "Main Options Menu", and it has only occurred on Android 4.0.4. I has happened in both the free and the paid version, but only a total of 3 times.
I do not have a device running 4.0.4, and my Galaxy Nexus running 4.2.2 seems to not crash when I run it. I created an emulated 4.0.4 device, and still cannot recreate the crash.
If you have a device running Android 4.0 or higher, can you please try to recreate this crash and send me a crash report? As I said, the crash seems to be happening either in the settings menu, or the Main Options Menu, or when transitioning between the two screens.
