    I don't know if this problem is related to the 4.3 update, but it started happening around the time I got that pushed to me.

    When the light sensor turns the screen dark when I bring the phone to my ear for a call, the screen will not illuminate when I pull it away from my head. The screen remains powered down. I have to press the power button to get the screen back to hang up the call. And sometimes, even the power button does not work, and I have to remove the battery.

    I've dialed *#0*#0 to get to diagnostic tests. If you wave your hand over that screen, it's supposed to turn green when the sensor activates, and I assume go back to being white when the sensor deactivates. Mine doesn't the sensor doesn't deactivate.

    Has anyone else run into this? Is this suspected to be a hardware problem or a software problem?

    I've not had the problem- my screen still correctly lights up when I move the phone away from my head. I feel like it takes an annoyingly long time to do it, but it works.

    Frank my man. You searched for light sensor when you should have searched for proximity sensor. It's right here on the front page:

    The CPU-Z app will show you the sensors operating.
