How do I uninstall the latest iPhone update?

.....how can I revert.....

You can't. Apple has never supported downgrading the iOS.

That being said, if you can tell us in some detail about what issues you are having, we might be able to help.

Please, how can I revert back to version that doesn’t suck so bad. This latest update has basically rendered my phone a piece of junk.

You cannot.

The vast majority have no problems, some don't like the glassy UI

so Either

Settings, Display & Brightness , Liquid glass, set to Tinted instead of Glassy

Or one or more of these

Settings, Accessibility, Display & Text size, reduce transparency

Settings, Accessibility, Display & Text size , increase contrast

Settings, Accessibility, Motion, Reduce motion

Settings, Accessibility, Display & Text size , Display Borders

Liquid Glass - Love It Or Hate It - It's … - Apple Community

When did you update?

Spotlight indexing will continue in the background for about 3-5 days which may be the reason you are not seeing immediate search results. It has not been the case for me that I have to enter 5-10 keywords to get results in Mail. Not sure what other functionality changes you are referring to with the browser, mail, or photos. If you want to turn off the Categories in Mail, then tap the 3 dots on top of the page and choose List View, which looks like it did before the update. The browser has not changed much at all for me and Photos is different but easily adjustable, much more than in previous versions.

Absolutely agree.

I’m guessing it’s all tied to AI, is there a way to turn off all AI functionality?

You can turn off Apple Intelligence (which first appeared in iOS 18).

You cannot turn off other artificial intelligence functionality (such as machine learning features).

Also, many of the things that people complain about with iOS 26 (e.g., Liquid Glass) are not AI features.

Yeah, I guess my phone hadn’t met the update criteria until recently. Plugged into charger overnight. Now I just want to throw it in the garbage.

Your phone was eligible on day 1.

Something that can prevent updates and also junk the phone is App store VPNs, particularly free ones. Is one installed?

It was introduced in September, and you didn't have to update to it.
