Well, it took Apple just less than a week from Beta 6 to release Beta 7 to developers and public testers. You can update either through Apple’s dev centre and public testing portal, or if you’re running the previous beta version you can update over-the-air.
The public version of iOS 9.3 is due to be release next week. The Beta 7 comes with improvements on night shift, display temperature, password-protected items in the Notes app, Touch ID, CarPlay features, expanded 3D Touch options on apps such as Settings and more.
If you’re a developer or public tester then give iOS 9.3 Beta 7 a go.
