does any one know what happens when pressing and holding red button in cell phones that turns the phone on or off?
i checked to contacts under keypad both of them was zero volt and non of then connected to the ground of its board.
I want my cellphone to turn on whenever i connected the battery what should i do ?
maybe i should and an rc circuit to it. (like reset circuit in micro controllers)
