Hi, im new to these forums. Anyways I was using my phone, browsing the web when one moment to the next Isee what looks like a hair. Upon closer inspection it is a crack. I ran my nail across it but it can not be felt. So I turned it off to see if I could see the crack, it can't be seen. Only when it is on or the battery animation is on the screen. It shows the typical characteristics of a crack, thins at the ends and thick in the middle. What are my options? Do you believe it to be a crack? Is it worth buying another galaxy s3?
