My Droid Inc. 2 has been doing this lately and i'm not exactly sure what it means. i'll frequently look at my phone for maybe a missed call or text message and i'll notice that my battery icon goes gray, and an exclamation point will be overtop of it. whenever i notice this, my phone is not on a charger. Does this happen to anyone else's phone? Has anyone brought this to verizon's attention as to what it might be?
