Ios 7 dynamic wallpaper

How come I don't get the Dynamic option for wallpapers even though I updated to ios 7 on my iphone 4?
I only see the Stills

Although using iOS7, there are certain features that certain devices are unable to use.

Here is a list of them:

Square and video formats and swipe to capture won't be available for the iPad 2
Filters in Camera (real time filters) will only be supported on iPhone 5 and iPod touch 5.So no iPad support, no support for iPhone 4 or iPhone 4S.
Filters in the Photos app won't be available on the iPad 2
AirDrop, the way to share file between devices won't work on iPhone 4S and earlier, nor would it work with iPad 2, and iPad 3.
Restrictions from previous releases for iOS carry on, so Siri won't work on iPhone 4, iPad 2 and Panorama won't work with iPhone 4 or iPad.
Dynamic wallpapers aren't available on the iPhone 4.

I'm sorry that you're unable to access some of the neat little features of iOS7!

  • Why is the wallpaper on my iphone not changing? It just stays on wallpaper setting screen. I have tryed everything like resetting it finding a way on cydia but nothing
  • Why can't I put panorama as my wallpaper in IOS 7? I have an iPhone 5 and I've seen videos of people putting panorama as wallpaper and it moves with the movement of the phone. It isn't working for my phone. Is it only for the iPhone 5s?
  • Where can I find the new iOS 7 iPhone blue space wallpaper? Right there in that background for the new coming iOS, I really like this background but can't find it anywhere, so I resorted to asking here. If someone could find the source or a clean, atleast decent quality version if it that I could use on my own phone, that would be terrific.
  • My iOS 7 doesn't have live wallpaper? I have my UDID registered and I downloaded iOS 7 yesterday but in my settings I don't have an option for live wallpapers and when I move my phone around I don't get the 3D look. How do I get them? I have an iPhone 4
