iOS 9.3’s most welcome new feature, Night Shift, has been getting plenty of praise from all over the tech world. Not least because it promises to put a stop to late-night smartphone usage hampering your sleep.
Night Shift tweaks the iPhone display’s colour temperature, switching it from blue light to yellow when it gets dark. Research has shown that blue light from smartphone and tablet screens can keep you awake, whereas yellow light is less likely to keep you in a state of wakefulness.
However, some users have complained that after updating to Apple’s latest software, they’ve not been able to automatically set Night Shift to turn on at sunset and turn off at sunrise. In fact, the option simply isn’t there.
This small glitch is easily fixed, though. Users only need to dive into the Settings app, head to Privacy, go into Location Settings and turn Setting Time Zone on.
This then allows the iPhone to automatically suss out where you are in the world, so it can tell Night Shift when the sun comes up and goes down.
Night Shift can be controlled manually, with users also able to set their own times for when the function turns on and off.
iOS 9.3 is available to download now for iPhone 4s and iPad 2 and higher. We'll walk you through the process in our step-by-step guide.
