Apple’s iOS 27 rollout is giving some iPhone owners a confusing start. Users attempting to move to the new operating system are seeing the “Upgrade to iOS 27” option in Settings, only to land on another screen that still identifies the download as iOS 26.7.
The issue appears to involve the way Software Update is displaying or delivering the new release, although reports from affected users are not completely consistent. On affected devices, iOS 27 appears under “Also Available,” but tapping it can open an update card labeled iOS 26.7 instead.
In some cases, users who first install the regular iOS 26.7 update continue to see an “Upgrade to iOS 27” option afterward. Tapping it then brings up another update labeled iOS 26.7, except this time the download is significantly larger — in some cases more than 20GB.

Some users say the larger “iOS 26.7” package is actually iOS 27
Reports on the MacRumors forums suggest that, at least for some people, the second and much larger iOS 26.7 download is simply iOS 27 carrying the wrong label.
One iPhone 16 Pro Max owner noted that the regular iOS 26.7 update was 1.02GB, while the update reached through the iOS 27 button was 15.22GB. Another forum member reported seeing a 19.73GB package on the second screen.
Several users decided to install the larger package despite the confusing name. One iPhone 17 Pro Max owner later confirmed that the installation completed with the device running iOS 27. The person who started the MacRumors thread reported the same experience: the update continued to identify itself as iOS 26.7 during installation, but after the final reboot, the phone was running iOS 27.
That makes a labeling problem look like the most likely explanation for at least some affected devices, with the correct iOS 27 software apparently being served behind an incorrect iOS 26.7 description.
But not everyone is seeing the same result
A discussion on Reddit shows why users may still want to be cautious.
One person said they downloaded the larger iOS 26.7 update and ended up on iOS 26.7, only to see the iOS 27 upgrade option remain available. Selecting it again reportedly led back to another large iOS 26.7 download, creating what the user described as a loop.
Another commenter similarly reported that iOS 26.7 started downloading after choosing the iOS 27 upgrade.
Those conflicting experiences mean it is difficult to assume that every oversized iOS 26.7 download will necessarily turn into iOS 27.
What should you do?
If your iPhone keeps sending you back to iOS 26.7 after selecting iOS 27, waiting for the Software Update situation to settle is the simplest option.
Users who want iOS 27 immediately can make a current backup and connect the iPhone to a Mac. Finder can then be used to check for the iOS 27 update directly.
If the correct update is not offered automatically, users can also manually select the appropriate signed IPSW through Finder using “Check for Update.” The “Restore iPhone” option should not be used for this process because it erases the device.
For now, user reports point to a messy rollout: some iPhones appear to be receiving iOS 27 behind an iOS 26.7 label, while others are getting stuck with iOS 26.7 and being offered the upgrade all over again.
