Chances are you're going to have to replace the screen to fix this issue, and I don't know of any way to do that for free, but add a picture and we'll see if we can figure out something that will help.
Screen damaged, only fix is to replace it But Motorola phones are (according to iFixit themselves) even harder to fix than iPhones Won't advise doing so by yourself
