Apple on Monday released iOS 9.3 beta 6 to developers and public testers. The update is available in both Apple's dev center and public testing portal, as well as via an over-the-air update for folks running the previous beta.
Today’s seed comes less than a week week after the previous beta 5, which brought about various changes and improvements to Night Shift mode, and some two months after the original 9.3 beta was pushed to developers.
