How do I get iOS 26 beta on a iPhone 12

It would not be a good idea to install a beta / test version on an iPhone unless you will be doing this on a spare phone......as Apple strongly recommends for very good reasons.

If you don't have a spare phone, wait for the official release of iOS 26. By the way, you might want to keep in mind that the first release of any new operating system always has the most bugs.

You wait until it is officially released, which is highly likely in the coming days. So just wait.

Apple has also officially stated that iOS 26 will launch on September 15th.

Why would you want to now? It’s officially released next week.
