When charging my 8100 at night ,later during the charge the indicator light starts blinking blue. I assume that means a bluetooth is enabled but I dont have a bluetooth and I never enabled it, Any ideas?

Well, first off check your Bluetooth (Options > Bluetooth) to see if it is enabled.

Second, turn off the coverage indicator (Options > Screen/Keyboard) and see if the blie blink continues.

Do you have BBAlerts installed?

Was your battery low?
Mine did that one time when my battery was at like 4%
Usally it would blink yellow,
but the blue came from out of now where?

Bluetooth is not enabled and indicater light is turned off and no the battery was not very low

Are you color blind?? J/k... blue is the bluetooth indicator. How it was blinking without the service being on doesn't make sense.

Pull the battery and reboot and see if it ever happens again.

already pulled battery out...that is my question. How can that be without bluetooth service. also no incoming calls come in like the bluetooth is activated. All phone just goes to mailbox
