iOS 9.3 beta 2 now available to Apple's public testers

Members of Apple's public beta tester program can now download and sample the second beta release of iOS 9.3, with a new Control Center switch for Night Shift.

iOS 9.3 beta 2 can be downloaded on a device enrolled in Apple's public testing program. The update can be found in the software update option in the native iOS Settings application.

The public release arrives two days after developers were provided with the second beta of iOS 9.3.

The biggest change from the first beta to the second is a new Night Shift control button in Control Center. Users can access it by swiping up from the bottom of the screen, and the quick access icon can be found in the center, between the timer and calculator shortcuts.

Night Shift lets users access and control display temperature on compatible iPhones and iPads, currently limited to 64-bit hardware with the most recent beta versions. Using device clock and geolocation assets to calculate local sunset, the feature automatically shifts display colors toward the warmer end of the spectrum for optimal night time viewing.

iOS 9.3 also includes individually encrypted notes, new 3D Touch actions, and offers the ability to pair multiple Apple Watches with a single iPhone. It's expected to launch to the public this spring.
