Apple usually releases an iOS update every month or two, and these updates have bug fixes, patches and occasionally new features. But if you want to try new features before they're widely available, you can sign up to be a part of Apple's Beta Software Program.
This program allows you to test beta versions of iOS software before wider release. New iOS features can be fun, but we recommend only downloading a beta on something other than your primary phone just in case the new software causes issues. Apple also provides beta testers with an app called Feedback. Testers can notify Apple of any issues in the new software with the app, that way the problem can be addressed before general release.
If you want to beta test the latest iOS software and help push it across the finish line, here's how to sign up for Apple's Beta Software Program.
Joining Apple's Beta Software Program on your iPhone
Signing up for the program takes a few steps. Here's how to sign up on your iPhone.

2. Go to the Apple Beta Software Program page on that iPhone.
3. Tap Sign Up.
4. Sign into your Apple ID.
5. You should already be in the iOS section, but if not, tap iOS under Guide for Public Betas.
