Hello all. My name is Richard and this is my first post with droidforums. I recently started repairing cell phones in my spare time and have come across a small problem. When dissecting a Motorola Droid X2, a small, black rubber piece fell out. It happened in the beginning stage when removing the back plate. Has anyone ever had this problem when taking apart their Droid X2? I have attached an image and sorry for the quality, currently using my back up phone while I repair my s4.
