I have an GPS-Tracking-Fitness-App where the user can track workouts in the background. All of that is working fine. No problem.

But SOME users - not many, but some - have the problem, that opening the camera app on their phones will kill my app. I can't reproduce it on my phone, but I once had such a phone in handy for debugging, and in the Xcode memory-debugger I could see that opening the camera-app there took about 2-3 GB!!! of ram and my app instantly got a low-memory-warning and was then killed.

I guess my app can't really do something about that?!? It does not use that much RAM itself. So I am wondering if I can somehow prevent that. I guess I did not miss any "background-mode : super-important-to-the-user" or so setting? :) Or is there a way to at least trigger a Push-Notification in such case? Not sure...

Any help would be greatly appreciated!
