The APP has nothing strange. Its all basic components and css. Indeed it works perfectly under android.
But on IOS: simulator and testflight has very strange behavior. Randomly a space between the statusbar and the header appears causing the whole app to shift down.
As you see the footer bar is clipped out of the screen, or the header is pushed out of his place.
This is my config.xml (i removed icon and splash to keep it short=:
