iPhone 14 became unresponsive after iOS 17.2.1 update

Same outcome here. 17.2.1 won’t run on my 13 Pro Max. InTune was never a problem before, but 17.2.1 doesn’t like it all. Unable to make or receive calls. I need my InTune profile for work info access and also need use of the phone for calls. Ugh

Mine is slow too emails sending checking the phone operation is jerky plus with iOS 17.2.1 my messages stop syncing to iCloud after talking to 4 senior reps one finally said “wait for an update it’s a known issue “ Man after all there 20 plus years of iPhones I can’t believe this one is slower than my iPhone 4 years ago 😳 Frustrating as all get out. Not that it’s a cheap phone either I paid $1700 w Apple Care

Same issue with 13 pro max , can’t make call or receive messages it is an iso bug and Apple needs to address this and fix , especially with how expensive their phones are! I’ve bought a new iPhone and the same issue feels like I’m just throwing money away

I'm experiencing the following, after iOS 17.2.1 update on my iPhone XS Max:

• Frequent freeze/crash in Apple Calendar app -- especially if I select an appointment for details/edit
• Inability to search Contacts (just freezes)
• Set-up ("connecting...") for outbound calls takes > 30 seconds
• iPhone battery lasts about 20% less time than before update
• Apple Watch battery lasts about 40% less time (dies after about 8 hours), when corresponding watch update applied

My iPhone is InTune-managed by my employer -- so suggested incompatibilities may be the culprit.

Actions I've taken that have provided no improvement:

• Change primary cellular provider (I have AT&T SIM and Visible eSIM -- selectively disabled/enabled each)
• iPhone "hard re-start"
• Reset network settings
• Substantial reduction of Contacts duplicates and overall Contacts entries
• Settings->Contacts->Siri&Search: Turn off "Show App in Search" and "Show Contact Suggestions"

I've tried a few variants to solve it programmatically, lots of reboots, and lots of hard resets with full data erase, but the only way that has helped me is total display replacement to the new one.

please fix this version before someone has an emergency and can’t utilize their phone for help!

I have iPhone 12 Pro ever since 17.2.1 I am having trouble, sometimes making calls connecting to my cellular, my Safari is completely crazy sometimes, sometimes I cannot go backwards. Sometimes the screen is so big I can’t zoom out, so I can see what I’m looking at the other day. My keyboard was upside down on my screen while I was looking at my screen my watch is not connecting to my phone properly, there were three of us in the car, none of us could make calls it would act like it was calling something, and then nothing would happen with the phone, but we would get a text, saying how come, you’re not answering your phone . I pulled over so I could test mine which was not working either and Finally one of us restarted our phones they started working again.

We're having exactly the same issue. iPhone 14 Pro Max updated to iOS 17.2.1 and became unresponsive making calls, WhatsApp messages and random inputs. Battery also getting very hot. Apple you should solve the problem on time my phone battery health is decreasing everyday 🥹🥹🥹

My husband downloaded the 17.2.1 update today at 11am and it is now 5pm and his phone has been unresponsive since. His phone got stuck in the update screen so he did the reset and it showed us a white loading screen that never completed.

He called apple customer service and they pretty much told us that we’re screwed. They gave us one more thing to try which was plug the phone in to the computer and try to do a recovery that way but the tech said that if that doesn’t work then we’re screwed and have to purchase a new phone.

I should probably add that we just purchased this phone (13 pro) so buying another one is completely out of the cards for us. I really wish apple would help more over this situation since this is the update they sent to our phones. We’re extremely stressed out over this but hopefully what the tech told us to try will work, if not I don’t know what we’re gonna do.

experienced this earlier actually. i've been experiencing issues w my 14 pro since the second it updated. i'm in alabama - we have gotten heavy snow and ice today, it won't be under freezing again for 3 days. the roads aren't drivable and i live alone. we've been warned to expect power outages due to the heavy ice. my phone froze earlier today with the lock screen on but backlight dimmed almost black, battery got SCALDING hot, and i could not restart it. force restarting didn't work, i attempted multiple times over the day. i had to let it just sit there for hours until the battery finally died, then wouldn't turn on for another two hours after putting it on the charger.

my parents live ten minutes from me and have a backup generator and fireplace and my stepdad has a truck that could make it to me if it was absolutely necessary but my car wouldn't have made it, all of our roads are covered in black ice. my wifi has been knocked out due to the weather so i spent the entire day worrying about what i was going to do if i lost power because had that happened and the phone never turned back on i would have no way to contact them at all. obviously it's fine now but this is unprecedented weather here and a scary situation to be in when you're unable to contact anyone.

this is on top of all the same issues you've mentioned as well. i've had an iphone since 2008 and have not had this many problems with an update since ios7, but it's interesting how it seems like every update for the last few years has barely addressed any of the real problems and created several that are substantially worse.

Same issues with my 12ProMax. After the most recent update to iOS 17.2.1 there are noticeably significant problems now. Initially I thought it was in my head or just off a day or two but no definitely not. I have restart my phone several times a day. At times it hardly picks up the wifi signal yet my other devices show a strong connection when I run a test. The phone lags in a major way and frequently. The screen dims randomly, it’s not the setting. I even transferred 80% of the files that were taking up storage to iCloud. I hate to complain but it’s irritating to think I’m going to have to trade in a phone that’s barely two years old along with costing $1200.

My iphone 13 pro on 17.2.1 update hangs and stalls after update, especially when syncing (or linking) contacts. Have used iPhone since 2012. Now finding more difficult to justify the expense. Get this fixed please

Apple.

Same here! I wish we still have the ability to delete or refuse unwanted updates, but how would Verizon continue to convince us that we need a new and better phone and that we must upgrade so they can make more money if they didn’t intentionally destroy our $899 phones just a little at a time. Yeah Verizon! I see you!!!

I tried the update too. I need to setup another device though as I stupidly changed some settings and unsure if that changed something too to improve it.

WhatsApp was still failing calls, then I switched off various Siri services. After that, WhatsApp worked well.

I hope the update stops the duplication, very hard to replicate what users at work are experiencing, but I have managed to just manually duplicate to force the issue.

I'll test a 17.3 device, will have to enroll it etc...... after that will force the issue and then update to 17.4. I'll feedback on this tomorrow.

Actually went through setup of 17.3.1 iPhone (reset via configurator last week) and can't replicate the issue, as in when I force duplication, WhatsApp doesn't suffer and phones isn't heating up. Annoying! Will have to check with users this week.
