Apple isn’t done with iOS 26 just yet. While the big update only rolled out earlier this week, a brand-new build has already popped up—exclusive to the iPhone 17 Pro and iPhone 17 Pro Max.

What’s New in This iOS 26 Build?

The new software carries build number 23A345, compared to the 23A341 version that landed earlier in the week. Don’t expect new features, though. This update is more about behind-the-scenes fixes than flashy upgrades.

The timing is interesting, as Apple had previously confirmed that a “very rare” camera bug in iOS 26 was affecting iPhone 17 models. While Apple hasn’t officially said anything, this new build likely addresses that issue ahead of launch day.

What This Means for iPhone 17 Owners

Apple doesn’t typically push out multiple builds of the same release so soon, which suggests this tweak was important enough to justify it before the iPhone 17 Pro hits shelves.

Early adopters will want the smoothest experience possible, especially with Apple’s most expensive iPhones of the year.

Looking ahead, iOS 26.0.1 is rumored to be right around the corner. Unlike this Pro-exclusive build, that version should roll out to all supported iPhones.
