How to Download the iOS 9.3 Public Beta

By -

Apple today released the first beta of an upcoming iOS 9.3 update for public beta testers, just a few days after seeding the iOS 9.3 beta to developers. iOS 9.3 is available to public beta testers alongside iOS 9.2.1, a minor update that is also in testing.

Among the features that come with iOS 9.3 is a new mode called “Night Shift,” which uses an iPhone or iPad clock and location data and automatically shifts display colors to the warmer end of the color spectrum between sunset and sunrise. The reasoning behind the feature originates from several scientific studies that found exposure to blue light could affect a person's circadian sleep cycle and keep them up later into the night.
