I've been facing serious issues on my iPad 4 running iOS 7.0.4.
I got a list of folders on the home screen that contains a bunch of apps. I couldn't launch, move or delete some apps in a folder, double tapping the screen to perform an action closes the folder. Switching pages inside a folder does not view the list of available apps. I reset the homescreen layout on my iPad and launched each app individually and things worked properly. Has any one experienced this?
