With the LG Optimus L9 is there a way to turn off the Proximity Sensor? During a call when I need to input numbers, the screen will go on and off making it difficult to accomplish my task. Usually I have to wait for the screen to figure out it is not close to my face, then input the numbers but by then it has interrupted the sequence of the automated service. Very frustrating at times. P.S. I do have a screen protector and a rubbery type protective case/cover for the phone.
