Users reporting crashes on startup, iPad 1 2? Where do we look?

Unity Engine

Hello,

I have been receiving a few complaints from customers that our App crashes on startup. The reports are very few in comparison to units sold, but it is still alarming.

At first I suspected an memory issue, but since the issue appears on both the iPad 1 and 2 and the app doesn’t allocate much memory in the first scene (it is just a quite basic menu), that seems unlikely.

In all but one reported case this far, doing a hard reset of the device fixes the problem. One customer says the problem has since come back and a hard reset didn’t work. (We have asked him to attempt a reinstall as a last resort.)

The only thing that happens on startup is loading of saved data, playing some music (compressed) and displaying a few sprites. We have never encountered this during development or testing. The game uses the highest level of Stripping (Unity Pro) and Fast - No exceptions.
Built with Unity 3.4.2f3 and Xcode 3.2.6.

Again, the problem affects a small minority of users. Any ideas on where to look?
(Sadly, there are no crash reports in ITC yet and I haven’t managed to get one directly from any of the affected users yet).

Many thanks in advance for any advice!
Cheers!

I remember a game made with Unity crashing if I skipped the GameCenter log-in.
Do you use the GameCenter feature?

Thanks for the reply!
Nope, no plugins or native calls. Well, we do use Ezgui and EZ game saver, but they are not really plugins and I fail to see how they could be causing insta-crashes. Also, the reports (this far) are thankfully from very few users, I think 4 in total.

Going over the code atm to try to find if the cause is programmatic, but am not finding anything…Frustrating!

Any known issues whatsoever with the versions we used that could be causing this?

TIA!
