My phone is an original Nokia C2. I don't intend to give up on it any time soon since old is gold. In addition, it is sturdy and functional. But there is one nagging problem though. Every time I replace the screen, it is only a matter of time before scratches appear on its surface. I have heard about the Displex scratch remover. Anyone with experience who can advise me or make a review about it? Where can I purchase one preferably online?
