IOS 27 is a pain. Can I revert back to 26.7?

I have a I-phone 13 (can’t afford a newer one). Question on the IOS 27. WHY DID THEY COMPLETELY REVAMP THE CALENDAR??

It’s not easy to use at all. I downloaded 27 for the security fixes and bugs, not to have everything be more confusing.

Sorry, no there is not supported way to downgrade any iOS version, there never has been.


Yes each year new features are added in a major release of iOS and there will be some changes. If you are having trouble with the Calendar app, it may be helpful to review the User Guide here where this starts at the first page and you can also view the Table of Contents. Each page has a section for choosing each iOS version, so you can even compare the difference when doing any particular task.

If there is something specific that you are having trouble with and it would help to post a screenshot, feel free to do that too as long as it does not reveal any personal information.


If you want to send Feedback to Apple on the Calendar app, you can do that here:

In the days of install by CD & even early downloaded updates it was possible to to back out versions.

Nope.


There was never an install option using a CD on iOS. Apple signs the iOS versions that are able to be installed on your iPhone, and currently the only signed version is iOS 27.0.1. When they release a new version, any older version is quickly unsigned and cannot be installed. You can no longer install anything prior to iOS 27.0.1, not even to iOS 27.0 if you wanted to downgrade from that singe point update, let alone to any iOS 26 version.


Now if you were talking about a Mac, it is possible to downgrade using a USB stick containing an older version of Mac OS, but even then it is not an easy process. That is not what we are talking about here though with iOS on an iPhone.

Too many unexplained buttons and settings in ios 27 now, user overload reached.

I don't disagree with you, yet we field questions from users that always want more options and also those that want the ability to turn other ones off and of course that leads to more toggles in Settings for the customizations. That is my biggest argument where adding every customizable option just increases the complexity. And when Apple makes a design choice themselves without any ability to change it, then the complaints fly in about how Apple is forcing some change on them.


Suggestion for Apple; press and hold any button or notice to get SIRI TO EXPLAIN IT, including how to disable it if relevant

Now with Siri AI and Visual Intelligence, with the Setting on the screen you can ask Siri what it is. For example, you can say "Siri, what is this setting called Learn From this App", and Siri will tell you what it is. If you want more information, you can continue the conversation without any activation word and just say "Tell me more" or "What happens when I turn it off".


In any case you can always send your Feedback or Suggestions to Apple directly here:
