I downloaded earthrot and when I pop open the slider and then close it back the globe freezes up and isn't totally on the screen.. I finally uninstalled it. It worked for awhile. Are the live wallpapers that you pay for the same or are they better?
Too hard to make a blanket statement about the available wallpapers paid vs non paid since they're all made by different developers with different skill levels. All you can do is read the comments before you buy and try it out.
