The public beta version might be buggy so -- when the time comes -- downloading on a secondary device is recommended.

– If you go ahead and install the iOS 26 public beta on your main device, then be sure to back up your phone’s data first. – Beta builds can have some privacy or security weaknesses, so try to avoid entering sensitive personal information while using it.

Apple announced in June that the release of iOS 26 would first appear as developer betas as usual, with the first public beta set for July. When it reaches general release it will be on the 2025 releases, iPhone 17 series, as well the iPhone 16 series and plenty of much earlier models.
