I am working on an iOS app and for some reasons the splash screen shifts a few pixels up or stretches ( it's hard to tell) upon start up. This is only happening on my iPhone 4 devices. I noticed that if I set my app to fullScreen (no status bar on top on the phone for battery life etc), there is no shifting.
Also, no issues on iPhone 5.
I've checked the image size of my Default.png splash screen and they are 640 x 960.
Thanks!
