iOS 27 update breaks blur feature for wallpaper on iPhone 17

Since update to iOS 27 on iPhone 17,

Not every issue an individual encounters on their device can be attributed to an iOS update. iOS 27 or later may have coincided with what you are experiencing, but that does not mean the issue was triggered by iOS. Coincidence in timing is not, by itself, evidence of causation.

If the update itself were the root cause, then every device running that same version of iOS would exhibit the identical problem. In such a scenario, the forums would be flooded with countless posts reporting the same malfunction, creating an unmistakable wave of complaints that no one could possibly overlook.

The absence of such widespread reports strongly indicates that the issue is not a general, system-wide problem with iOS 27 or later, but rather something specific to the individual device, its configuration, installed apps, settings, hardware, or another interacting factor.

In short: iOS 27 or later may be a coincidence in timing, but there is no basis to conclude that iOS itself triggered the problem simply because the issue appeared after the update.

See what each update does: About iOS 27 Updates, About iOS 26 Updates, About iOS 18 Updates, About iOS 17 Updates, About iOS 16 Updates, About iOS 15 Updates, About iOS 14 Updates, About iOS 13 Updates, About iOS 12 Updates, and so on...

Simply stating that the Home Screen wallpaper blur feature has stopped working on an iPhone 17 since updating to iOS 27, and immediately blaming the iOS update, suggests that you may not have thoroughly tested the issue before drawing that conclusion.

Community Forums should be used to investigate problems, share verified findings, and help users resolve issues—not merely to attribute every malfunction to an iOS update without concrete evidence. Before claiming that a feature is broken because of an update, it is important to test the available settings, explore possible workarounds, and establish whether the problem is genuinely caused by the software or by some other factor.

Please refer to the picture below. It demonstrates, step by step, how to enable the Home Screen wallpaper blur feature on an iPhone running iOS 27.0.1.

Rather than prematurely concluding that the feature no longer works, it would be more constructive to follow the demonstrated steps and verify the result. Sharing a reproducible solution backed by practical testing is far more valuable to the Community than making unverified claims about software failures.
