Is there any other way to clean up the glass covering the cam at the back of phone? someone said use kerosene to wipe it para yung mga gasgas mawala. I doubt this.
For cleaning? Or for fixing scratches?
For cleaning, just use microfiber cloth. Occasionally, damp it on alcohol before using it to wipe the lens.
For fixing light scratches, use banana peeled skin. That's a trick being used on scratched cds. I'm just not sure if applicable on glasses, but it should improve lens detection as it does on scratched cds.
