Hey guys so I bought the s2 skyrocket today, love it so far, but I have a question, certain times when I'm scrolling and get to the end or the edge of the pages, theres this blue film that comes on and then disappears, it does it if you're like browsing the web and get all the way to the end of the page it will come on.. Is this normal or is the phone faulty?? Any wisdome would be appreciated ! Thanks
