I am searching on internet about my problem but, I am not sure exactly what I have to do.
Before I submitted my app in App Store (iOS), I tested the app on different devices through XCode (I tested on iPad 2, iPad mini, iPhone 4s and iPhone 5s) and It ran very well. In addition, the same application I exported to Android and It runs (now) very well.
But, the problem comes when the App Store accepeted my app and I update the application in that devices before I say. And on iPad 2, iPad mini and iPhone 4s runs well. However, on the iPhone 5s appears the application but the iOS camera don't function, It appears a black screen behind the UI labels.
I have to say that iPhone 5s has allow the camera using. But I don't understand why through XCode on the same iPhone 5s runs well and then, through the App Store on the application appears black fix screen.
I am using Vuforia 4.0.105 and Unity 5.1.
I need help because I don't know what I have to do to fix that bug that only appears on iPhone 5s.
Thank you so much!!
