[H] Bluetooth Auto Redialing feature

A few customers have come in and mentioned or complained they the bluetooth they have will automatically redial the last number they called when they press the send/end button on the earpiece itself when they are trying to make a call.

That can be a handy feature in some circumstances, but for the most part its rather annoying (and even more annoying for me because I don't know how to fix it). I assumed it was a phone feature and I called the network provider and they can't troubleshoot bluetooth stuff and said call the manufacturer of the bluetooth. Customer is gonna try it, if that doesn't work she will be back so I want to be prepared.

So, How the hell do you turn that off? Is there some kind of trick/key press code to keep it off forever, or is there a certain way to do this every call?

I assume the customer wants to set up the voice recog. and just press the button on the ear and say "call John" or whatever. The trouble is that it just automatically redials before she can do anything.

Also, nobody answered my other question in that other thread so


A customer had just bought her phone and the battery life is rated at 3.3 hours talk time (some basic samsung phone) and a week standby. And she uses it with a plantronics headset and she said whenever she used the headset the battery seems to drain from full to nothing after like 10 minute and 3 phone calls.

A phone and a bluetooth have their own batteries so I was wondering that when you put your bluetooth power to 'on' on your phone does that make your phone use up more energy to send/receive bluetooth signals (even while on standby)?

Like all things I would assume this is probably due to the lower end models of phones and it varies from make/model.

PS-
Oh yea
Also, if you charge your phone through a data cable to USB on a computer is that better/worse?

most redial functions opereate when you push the button twice.
Bluetooth is a battery drainer, especially when it goes out of range and tries to reconnect.
Keep both devices close, on the same side of the body.
