Are there any known issues with the iOS 18 Update?

Do not update!!!! I have iPhone 13 Pro Max and it all crashing!!!! I don’t know what to do but it’s terrible!!!! I acutely don’t have phone⛔️⛔️

DONT DO THATS!!!

It seems to me that every Apple update downgrades the device and releases a barrage of issues that are impossible to get rid of. The battery drain makes me think of viruses, hackers and spyware, in this case probably them sticking their noses into our privacy. Then, when we reach out to support, their invariable response is always: 1) can you do this on your phone/device? Did you go through a reset (more problems, more loss), did you turn off and on? and all the usual idiocies to wash their hands of their appalling service and dump the blame on our side; 2) where do you live? (check postcode, next predictable sentence is ->) your nearest Apple certified store is bla bla bla (usually several cities away from you and involving an hefty payment for something that’s not there because the problem came from them.. as usual); do they reimburse you? No. Do they offer you the right fix and recovery of your losses? No. Do they admit to being wrong? Never. I gave up on contacting support and rather go with a faulty product that is still better than the non-solutions for the devices non-issues when the fault lays with their updates and at their door.

a lot of brand new iPhone 16's are already on iOS 18 have software issue's right out the box....reading is fundamental.

99 per cent of users, including me would disagree. It is not generally stable. It is the least stable of any update to date. Please do not tell people to install it. If you are getting kick backs or work for Apple, this is highly unethical. If you do not work for Apple or get kickbacks, then this advice is just irresponsible. As you can see a clear majority of users have major issues with IOS 18 and the patch. My notes app has not worked since installing IOS 18 and the patch. I have lost so much time that I am not using other apps just in case they slow me down. Lucky my iPad is running iOS 17 something and K can use that as a workaround. Please contribute something useful or stay off the forum. You’ve not even stated which iPhone you are using, which begs the question, is your input simply made up? If you are truly not having issues it would be helpful to know which phone you have. Otherwise please accept that the majority are having issues and stay out of the conversation.

I recently updated my iPhone 15 Pro to IOS 18. Since then, I have nothing but problems with my phone. The camera is zooming in and out on its own and won't take pictures. The flashlight goes on without prompting. It will switch to voice recording on texts without prompting. CarPlay music isn't working either. The music plays from one speaker, then turns off. When restarted, the music then plays from the phone, while appearing on my car screen and reacting to my touch to play or pause. I'm in constant reboot mode foR my phone. IOS 18 is a nightmare!

Apple Needs to issue a fix for whatever bugs this IOS 18 update has.

Maybe someone not having issues and it’s good but other does… photo on my iPhone 12 mini with iOS 18.0.1 freezing and not responding when I try to close it or tap on search not each time but it’s happening. I have near 5 bugs that I facing all the time 1 safety check, 2 Siri icon glitch in messages when I on/off iMessage, 3 bug in the apps in settings, but most annoying it’s parent control. And yes I restarted my phone, deleted all settings and even data. Nothing not helping. It’s a good phone but he has bugs right now on iOS 18.0.1 it’s a fact

Was your device Jailbroken? If that's the situation, please be informed that attributing the issues to iOS updates may not be accurate.

I have been updating my devices ever since I bought my first device in 2009. iPhone 3Gs, 4S, 5, 6, SE (1st Gen), 7, 8 and iPhone 12 Pro, iPad Pro, iPhone 13, Macbook Air 2019, MacBook Pro 16"

I never had any issues with any iOS, iPadOS, or macOS updates to date.

I would personally recommend everyone update their devices instead of listening to rumors from people who may not have kept their devices free from any spurious software.

iOS / iPadOS devices cannot be hacked or infected with Virus / Malware / Spyware if it is updated to the latest iOS/iPadOS unless you have intentionally downloaded spurious software or unauthorized apps directly from the internet and installed them on your device or/and have Jailbroken. 

iOS updates generally aim to enhance user experience, boost security, and fix bugs rather than disrupt core features. Issues after updates might stem from underlying, unmentioned factors. Updates won't typically alter personal data but may refine settings or features. Backup before major updates for safety. Review Apple's update details and backup advice for a smooth process.

This seems purely coincidental so please check the Setting on your device.

Messier,

Well....

For me, I have not experienced any of the issues you have described. My recent updates to 18.0 and 18.0.1 were without issue. If you are unhappy, might I suggest buying a different product.

As far as the photo app being rubbish, that is subjective and you are certainly entitled to your opinion. It is not mine. Generally speaking, no one likes change and I get that. With that said, you can find ten people in a thousand that think anything under the sun is rubbish.

Cheers!

Do not update. I sporadically get text messages and incoming calls now. The calculator has no memory so you can’t repeat calculations by hitting the equal button. Apple support is worthless and refuses to acknowledge the problems they just recommend a factory reset. I just did that. It doesn’t work. This honestly has me considering buying an android after nearly two decades of using an iPhone.

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.

Since updating, I can’t watch anything on my phone on TV using a Lightning to HDMI adapter. It worked perfectly before the update.

my only problem so far which to me is a biggie, i transfer the files from my phone to my windows pc. I have done this since 2012? i can then go back and access these files and delete off the phone, my own icloud so to speak. Since the upgrade the .MOV files can no longer be seen as thumbnails in explorer and have no Length, all files prior still can be seen, if im looking for a specific file the thumbnails saves me opening 1 hundred files to find the 1. i also sort in length as this can save me time too. I also delete .mov files with no length (jpeg live files)

4 iPhones in my household (15 Pro, 14 Pro, 15, 13) all reported much reduced battery life on 18.0. None of us regularly charge our phones during the day and post 18, we all are having go plug in each afternoon to keep us topped off till bedtime. I'm aware that new major OS versions can eat some battery while they reindex etc but this has gone on since release. 2 of us were on public beta and both noticed it pre-golive.

Just put 18.0.1 on and hoping there's some reprieve, although the release notes don't specifically mention battery life. It's also not beneath apple to just fix something like that and never speak of it again...

Do not update to iOS 18 and AI

silence unknown callers when turned off still silences unknown callers

turn off volume limits notifications does not stop the notifications

repeating events in the calendar cannot be moved to a forward date

repeating events in the calendar cannot be changed from repeating to “never” repeat

photo app as people have mentioned is rubbish

I’m having very similar problems with the calendar and repeating events ….if I move the repeating event forward let’s say 4 weeks to November for some bizarre reason it also makes copies of this event for June, July, August and September this year

I showed this to an apple support person and they said

“maybe it’s taking time for iOS 18 updates to filter through”

my thought maybe there’s a bug that apple need to fix
