Hello- My green LED light came on randomly last night after I turned off my network connection. I checked my LED coverage indicator and it is OFF. I had a condensation issue with my phone yesterday and wonder if this is related. I've never seen the green LED indicator or used it before.
The green indicator light on my previous phones (8130 pearl and 8330 curve) meant that the battery is to low for cell use. Therefore you can only make emergency calls until you charge up the battery. It also flashes when you have no service. Since you turned your Network coverage off that green LED indicator flashing should be normal.
