Apple has released the first public beta of iOS 12 for iPhones and iPads. Unlike the developer betas, which can have major bugs that interfere with core features, Apple's public betas are generally more stable (but not completely bug-free). With that in mind, we expect that testing pool to dramatically increase with the next release, which will filter through as iOS 12 beta 3 and iOS 12 public beta 1 - both of which will be exact same builds but will be carrying different numbers for differentiation - and we expect the, to land on our devices on either Monday, July 2nd, or Tuesday, July 3rd. The first thing that you will need to do is enroll your devices in Apple's beta program.
Changing your phone habits: The most notable feature Apple has added to iOS 12 is arguably a handful of controls called Screen Time that let you monitor how much you're using your iPhone. This time it has made iOS 12 public beta available for all devices running iOS 11.
Apple has released iOS 12 and tvOS 12 public betas. You could quickly run iOS 12 beta on your primary phone or tablet without worrying too much about bugs and stability issues. Just go to Apple's website to become a member and start downloading the new software. Downtime, another setting, allows you to set blocks of time where you can only use authorized apps, to keep your distractions down.
Apple showed off the new version of iOS earlier this month at WWDC.
From there, it's just like any other iOS update. If you have an iPhone 6 or an iPad Air for instance, you should see a big improvement when it comes to launching apps, triggering the camera and entering text. You can also set your own shortcuts through Apple's new "Workflow" app, so that Siri can take care of several tasks for you with a single command.
