Apps don’t work after updating to iOS 18.1.1

I updated my iOS to 18.1.1 on my iPhone pro max 16 last night and this morning I’d say about 80% of my apps refuse to open. Reinstalling doesn’t seem to solve the issue. Causing me major issues as I can’t open my banking apps to verify transactions. Can anyone tell me how to roll back my iOS update or if there is a fix?

Just updated to 18.1.1. The vast majority of my apps start to open, then the icon disappears and does not start. Don't have a VPN, did force reboot several times. Very upset with Apple that they push out this updates, and then we must uninstall and reinstall all of our apps. REDICULOUS!!! Haven't seen any solutions from Apple, and the posts I read do not help.

I feel exactly the same way D1..!!

QUITE BOTHERSOME, to say the least..!! Through trial and error, I’ve been able to fix most of the issues I had or at least can work through them now. Initially, I had a problem with the calculator, and editing photos, but I figured both of those out. The issue that I still have, and it REALLY BOTHERS me, IS THAT SIRI DOES NOT WORK..!!

U N B E L I E V A B L E . . . . ! ! ! !

I used to use Siri quite a bit, she was both quite informative and enjoyable to use. You almost felt like you were talking to a real human being.

NOT ANYMORE..!!

most of the time if you ask Siri something now, she’ll respond with her two syllable “ah huh..?!”

then, when you proceeded to ask her a question, you get a message on the top of your screen.

Siri’s VERBAL RESPONSE IS NOW GONE.

S M H . . ! ! 🥲🙁😡

ME TOO, Larry..!!

I enjoyed SIRI and used it often, but “Hey Siri…” DOES NOT WORK on my iPhone AFTER the iOS 18 UPGRADE..!! UGH..!!

SPECIFICALLY, when I ask SIRI a question NOW, I get the normally expected two-syllable response of “ah huh…”, THEN… when I ask my question, there is NO VERBAL response from SIRI, ONLY A SILENT MESSAGE at the top of my screen.

And to make matters worse, that message DISAPPEARS within a few seconds..!! UGH..!! 😡😡😡😡😡

I was so pumped because I've been looking for an answer since upgrading a few days ago. Search is the main feature that broke for me (search in mail. search in spotlight. search in notes...). I reset network settings, as described above. After the reboot I was excited because things seemed to be working, but, as some other users have mentioned, search stops working again about a few seconds. I'm not a hater, but this is, indeed, the worst iOS update I've ever experienced. I hope this is fixed quickly. Everything takes 10x longer on the phone without search.

Still having issues here too weeks later. Every new app I try to go back to errors out. Frustrating!

Then it sounds like you need to schedule an appointment with the Genius Bar at an Apple Store. Or take it to an authorized Apple service provider for examination and diagnosis. If you are not willing to do that then continuing to create other posts with the same question is useless.

Calendar is all jacked up for several users. Notes app is still there but either most or all of the separate notes have disappeared. Group chats are missing parts of conversations - both past and present. There is a major delay in receiving text messages - not a carrier issue.


Will the new iOS 18.2 correct these issues and return our phones to the state they were in - that is, all apps working as advertised and the restoration of items such as Notes?


Makes me wonder if the iOS's are beta tested on all models and devices before pushing out the code. This was a bad deployment and needs to be corrected. This is not a good look for Apple.

I can't answer that as I never had any issues with Notes or Calendar or anything using iOS 18.1.1. (or any other version of iOS 18). And I like the new version of Photos.

Apple makes beta software publicly available. Lots of people participate. You can, too!

after installing the update half my apps won’t open and my phone is freezing. I can’t even get my settings to open up. Talked to my phone provider and they sent me to Apple support. After troubleshooting with an apple representative for over an hour , they sent me back to t-Mobile saying it is my network. Funny how everything was perfect before the update. The representative said “ software updates improve your phone, they don’t break your phone”. Lol well this update did break my phone!!

Yes Im having issues with the phone disconnecting from home WiFi. Also Santander app keeps freezing when I’m trying to pay someone so have to use my iPad instead which is not good. Im loathe to update again because it may make things worse. Ive lost two iphones in the past due to updates killing my battery. I am seriously considering going over to android now 🤬
