Four months after launching iOS 9, Apple revealed this week that version 9.x releases are now installed on 75% of devices. The company rolled out iOS 9.2 last month, but as ever, a new version of the operating system is already in development. After seeding iOS 9.3 to developers earlier this week, the first public beta of that version is now available.
You"ll need to be signed up to Apple"s Beta Software Program to be able to install the new iOS preview as a non-developer - but if you do register, you"ll also get early access to future versions of OS X.
For those who have signed up, the iOS 9.3 public beta will be delivered as an over-the-air update, bringing a wide range of new features, including more 3D Touch support for first-party apps; the ability to protect notes with passwords or Touch ID; additions to CarPlay; improved personalization in the News app; a new "Night Shift" mode that adjusts screen coloration depending on the time of day; and more.
