Are there any known issues with the iOS 18 Update?

Because this is a user to user forum, not Apple support. If you want Apple support, you need to contact them directly.

I updated my phone and I can no longer send text messages later. Is anyone else experiencing this?

It's horrible. Can't access internet. Can't find network. Don't do it.

I have an iPhone 14. Yahoo emails are not coming through. Emails on iCloud and Exchange are coming through. I’m sure Apple and Yahoo will say it’s a problem on the other’s end.

I updated 13 pro to 18.0.1, I go to the camera, the camera makes strange sounds... Everything was fine on iOS 17. Is there such a problem?

18.1.0 my calendar has multiple problems. Too many colours now.

events duplicating and Tripling on the same day and onwards. Now able to delete or edit events at all.

terrible!

I don’t know but I having problems with my iPhone 14 Pro Max after update the iOS 18. I got a massage said my camera wasn’t working properly. I don’t was wrong I try a few times turning my iPhone ON and OFF but still got the message.

My phone won’t connect to CarPlay at all. The Bluetooth works but not car play. I’ve tried all of the troubleshooting and it just doesn’t work. I’m regretting this phone and upgrade. I just turned my 14 for 16

I had no issues with updating my iPhone 14 Pro to 18.0 or 18.0.1 or any other update for that matter and I have had most iPhone models since they were introduced. A minor glitch or two, yes, but they were addressed in a subsequent update.

AND I've never been abducted by aliens, I think. I couldn't resist :-)

I'm trying to evacuate Clearwater from Hurricane Milton and I just updated last night hoping it could help after hearing everyone tell the people that said it made their phones crash. Well let me tell you. I have spent 10 hours trying to communicate with family and people and almost smashed my 15 pro max because its like playing Call of Duty on an Atari 2600. this is the worst thing ever. I am not kidding. Do NOT even attempt if you are possibly concerned about being unable to send a simple text. I would have so much more to say about this but I came on here praying I could find out how to uninstall because all I can find is how to uninstall the beta. Now I might as well be without a phone because anyone that has expereinced this knows how frustrating this is.

OMG! It’s the worst. Apps close out. Phone gets hot. Can’t hold a charge. Photos redesign is not customizable like before. I can’t have WiFi and data on at same time. EVERYTHING takes forever to load…like dialup slow. Touch screen is delayed and really unresponsive at times. Entire operating system freezes so you’re stuck on a page or something and you can’t swipe out of it or get it to load or respond to touchscreen! Glitches so much it’s annoying 😤 

I feel like this update failure is targeted towards older iPhones. Mine is 2020 iPhone 11 Pro. Touch screen freezes up. Screen will turn black and you can’t get it to come back. Emails and messages aren’t showing up as sent or disappear entirely. 

Honestly, this update made me buy a new iPhone 16 Pro. I think it’s Apple’s goal to keep consumers buying. Doesn’t matter that Mac’s are quality built. If people keep the same iPhone for 5 years, what better way to make sales than to make older models have issues so they’ll feel it’s necessary to replace it and upgrade. The update on my 2017 iPad cause programs to crash daily 🙄 The touch screen isn’t as responsive. Lots of issues staying connected to WiFi networks. I’m so annoyed 😒 

I’m so trapped in with Apple. I’ve only ever used Apple. All my data, photos, music, documents, and everything, means I’m in too deep to get out. The amount of time and work it’d take to make all of that PC android compatible is ridiculous. 

I couldn’t figure out why i am having so many sudden issues with my iPhone 12 pro and realized after deleting a ton of stuff bc it claimed i didn’t have enough storage to update that once it updated to 18, my phone has had countless issues including the fact that my battery is not charging and draining immediately! The pic app has changed and hard to edit. My phone is going into private mode. I can’t easily find my passwords etc Please help! How do i fix this mess? My phone is on the verge of dying and won’t charge now. I’m not buying a new iphone!

My phone keeps freezing, I can't use apps, My 0 button doesn't work, and this is not good in case of emergency or being a freelancer...The 18 update slowed my phone down, it won't hold charge, overheating, freezing, and buttons unusable, seriously wth?!

iPhone 12 Pro, iOS 18.0.1, WiFi connects but doesn't work (can't pick-up eMails, can't browse, phone reports no internet connection, and I've tried all the various "fixes"). Fortunately my cell data service still works.
