I have this problem, it drives me nuts!
The entire app is working just perfect in emulator, but on the phone, if I press back it loads for a split of a second the page, but then it brings a white page and I cannot do anything to it.
The app consist in 9 tabs on the main screen, and a back button for iOS.
It's built on app framework.
Any idea why and how to fix it?
I cannot make the debugging feature to work...
I will archive the project and send it to you in a private message.
L.E. It happens after I build it and try it on device. In emulator it works fine.
