Because it looks like the design of the ZUS has changed, the pictures of the charger on the splash screen haven’t changed. If this app will be used my different revisions of the ZUS hardware, you might want to rethink about the image that you want displayed on the splash screen. At first, I thought I had a different device. The silhouette of the charger used for the app icon is different as well.
As an aside, I do like the new slimmer design.
