screen protector Yes or No
No, I don't, I can't. All the photos are more or less out of focus. The best way to look is to put it under a desk CFL lamp, and see, without camera's flash. However seeing that it's an N8, it's possible that it won't have any / much noticeable scratches. One of the best built phone ever made. The only phone I used without any protector and had no visible scratch under normal lighting was the S2.
