A while back I cracked the lens on my rear camera. I bought and installed a replacement lens and now every picture is blurred. The camera doesn't try to focus on anything at all. Is there anything I can do to fix it?
Maybe your camera has been damaged when cracked the lens. At first, make sure you connect with the main board tightly. Then Put your camera on another working well S4 board, and to see if it still be a good camera, If not, you should replace the whole camera.
