Have a question over my Huawei Mercury phone. When I turned the phone off, removed the battery (since I needed to change the sd card), and then replaced the battery, the phone's LED lit up. The LED light stayed on until I pressed the power button to start the phone. My wife's M886 will turn on by itself when the battery is place back on the slot, but the LED light will not come on. So I am stunned; two identical phones and yet they behave differently. Any ideas what could be causing the LED light to come and stay on until the power button is pressed.
