The camera of my Galaxy S2 was very scratched and milky, images could you no longer reasonable to do with it. With microfibre cloth and Displex disappeared after about 3 minutes polish the Milky - now the images were blurred due to lower Katzer. After another 10 minutes polishing the deeper scratches were gone. The plastic shines and the camera takes pictures again top. The tube is empty - I was a little surprised at how quickly depleted 5g are.
