There's plenty to look forward to in the upcoming iOS 15 update: SharePlay in FaceTime, new Focus modes, better Maps and Weather apps, as well as deeper integration across Messages, Photos and more. Though there's still some time to wait before the next OS officially rolls out, those eager to try early versions of these new features can check them out starting today. Apple has released the iOS 15 public beta and if you're curious enough to install potentially unstable software, you can run it today. Additionally, Apple also dropped the public betas for iPadOS 15 (which shares many of the same features as iOS 15) and watchOS 8. Make sure you back up your data before you begin!
iOS 15 will be compatible with iPhone 6S and later (including both generations of the iPhone SE), as well as the 7th-generation iPod Touch. Those hoping to test watchOS 8 will also need an Apple Watch Series 3, 4, 5 or 6 running the iOS 15 beta. If you have compatible hardware, all you have to do is sign up for Apple's beta program on its website here. You'll get a notification that it's ready to install (or you can keep looking at your "Software update" page in Settings). We've been using a developer beta build for a couple of days and, assuming it's largely similar to the public beta, the software seems fairly stable with occasional glitches in specific apps.
While your devices are enrolled in the beta program, you'll receive updates automatically when they're publicly available. If you've played around with the preview and decide you've had enough, you can revert to an older version by unenrolling. Once again, to ensure that your data is safe, make sure you perform a back up before getting the beta.
