I'm not positive this is in the right place, but I figured it'd be close enough. The very upper right hand corner of my screen has dust. I work construction so I expect a small amount of dust to get in somehow someway, but there is enough that when in the sunlight I can barely make out whats underneath a half inch by half inch square right where the time is displayed, and I think the volume rocker is to blame for this. So my options are to replace my phone and have to unroot, reprocess everything, re-download everything exc..or try to take the screen apart and simply learn how to clean it. Has anyone got any experience in this? Any stepped schematics that would help me tackle this? Or do I just get a new one and start over again and pray the issue is resolved? Thanks in advance.
