Screen goes black and cannot turn back on for 2-3 minutes

[A Stark]

I normally use Bluetooth in my car with the phone (last phone was a 2 year old Samsung Vibrant, and did this all the time)). Today, had the navigation going, and was talking to someone on the phone. The call continued, but the screen went black, nagation didn't work anymore, and the call could not be hung up.

On any other phone, to 'reset' quickly, you just take the battery out. Since there's no way to take out the battery in a Nexus 4, what do you do if you must reset? Thankfully, the phone came back on after a few minutes (and pushing the power button over and over)... but what is comparable to pulling out the battery in a Nexus 4?

Anytime you are using Navigator, a call can come in... so the phone locking up when Bluetooth and Nevigator are active, with the phone in use, is not ok. Has anyone else encountered this?

The other day I woke up and my LED was blinking for a notification. I have Light Flow Lite. I went to turn on the screen and nothing happened. I tried several times. Screen wouldn't turn on. So I just randomly held down the volume down rocker for several seconds and then the phone rebooted. Don't know if this was related to light flow or not.

Check that your screen protector is not covering the sensor.

I don't use one.

This happens to me on rare occasion as well, always when using bluetooth in my car. I just toggle my car's bluetooth off and on and the phone snaps out of its stupor.
