You Must Turn on Location Services to Use Night Shift
RUSH: I've gotta address this. Forgive me. It won't take long. I spent some time yesterday and a couple days prior to that talking about the new software for the iPhones and the iPads, iOS 9.3, and I was talking about a feature called Night Shift that takes the blue light out of the computer display at night, which blue light replicates daylight, which makes your brain think you're still in the daylight, makes it tougher to fall asleep. This is scientific research.
So they've come up with a feature called Night Shift that takes the blue gradually out of the display as the night goes on. It's warmer versus cooler and the screen actually becomes little red or yellow depending on how much blue you take out, it's adjustable. And I said that you can either schedule it or have it automatically come on and off. At sunset come on, at sunrise it comes off. I've got people e-mailing, "Rush, that option isn't on my phone, I don't see sunrise or sunset."
There's a reason for that. And I would not do this if I hadn't been inundated with questions about it. In order for the sunrise, sunset option to show up on your device, you have to have location services turned on. If you don't, that won't display. I know a lot of people keep location services turned off so that whoever can't track you. So that the NSA, so that the CFR, so that the FBI, whoever, can't get through the day without knowing what you're doing, you turn off location services.
