How do I install iOS 26 on my iPhone 14?

iOS 26 won't be released until the fall.

There isn't even a public beta version yet. Even once there is, installing a beta test version on your main iPhone – the one you rely on every day – would be a bad idea. When you sign up for a beta, you are signing up to be a lab rat, or guinea pig, for software that may be incomplete and full of bugs.

The point of the beta test is to help shake out the bugs, not to give you a stable, polished release several months before everyone else gets it.

You wait until it’s released sometime in the fall.

You can’t, iOS 26 hasn’t been released to the public yet. Apple anticipates a release of fall as Jonathan Burger states.
