Audiovox smt5600 blinks amber light upon plugging in charger and wont charge and the (!)icon appears on the screen whichi n the manual means that the battery is either at too high or too low of operating temp, which cannot be te case because im using it in normal operating conditions. also when i do unplug the charger after plugging it in, it turns off the phone automaticaly. almost like there is no more power in the battery, even when the battery was fully charged when using it for the first time. does that sound like a battery prblem or a phone problem. i hope its a problem with th batery because id be willing to buy a new battery. hope you can help me.
