I have a status bar with style UIStatusBarStyleLightContent(white text). But when the Application is sent to background, in the task manager, the status bar is shown with black text and it stays black until the application is fully in foreground again (it is black through the whole go to front animation).
I observed this behavior only in iPhone 6 and iPhone 6+ (simulator and actual device). It shows up white (as expected) on iPhone 4s, 5 and 5s (tested on simulator)
I just found a solution. It is a bug which gets solved if the proper splash screens are defined.
