Proximity sensor on at all times

Since updating to 11.3 (15E5189f) my proximity sensor appears to be active at all times, in all apps. If I place my hand up to 1-2 inches from the prox sensor, the screen will go black, as if I were making a call and it detected the phone was raised to my ear. If I remove my hand, the screen is restored. Probably not great for battery life, and definitely a challenge when holding the phone in landscape, where part of my hand regularly triggers the prox sensor.

Me too. Didn't notice before yesterday so I think it’s only the latest beta.

Oddly, it is not happening today. I suspect something turns the prox sensor on and doesn’t turn it off again.

I got the 11.3 update only about two weeks ago, and have been noticing this ever since. It is a real PITA. Unfortunately, it looks like no one has posted a solution yet...
