But I just have a scratch in the cover. Someone said the glass could get shattered/cracked itself because of Samsung design flaw . http://www.ebay.com/itm/BLK-Rear-Cam...item43c99de725
XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. Are you a developer?
