I bought a used Droid X for $30 "AS IS" for my mother-in-law to use. Everything works great, except there's a real fine scratch across the lens cover, making for some cloudy / foggy pictures. Does anyone have any ideas on how (if possible) to repair the scratch? Wondering if toothpaste, or some other chemical / solution would help fill in the scratch on the glass. It looks like it is part of the whole camera assembly, so I'd rather not take the phone apart or have to find a new camera. Thoughts?
