iPhone calendar freezes in IOS 11

When adding an event in calendar, if you try to add a location, the screen locks up and you have to force close the app. I have done a complete reset and download of IOS 11 and still have the problem.

I had this exact same problem. I have an iPhone 7 Plus with iOS 11.0.2. (I tried everything - worked with Apple Support, Senior Advisors, Genius Bar and nothing worked).


I think I discovered how to fix the issue on my own. At least it worked for me. I noticed that whether I typed a letter or a number as the first character in the location field, it took a long time to populate the choices below (addresses, places, etc.). I thought maybe it had something to do with the Contacts data on my iPhone and that maybe there was an indexing issue. Here are the steps I took which resolved the problem for me:


I suggest being on WiFi for this process:


1. Go to Settings / Accounts & Passwords.

2. Under Accounts, select each Account to see which ones have Contacts turned on.

3. If you use Work (Exchange), this likely the issue. Turn off Contacts. When you see the message “Are you sure you want to continue? All exchange contacts will be removed from your iPhone.” Select “Delete from my iPhone”.

4. You will see a message “Turning off Contacts.” Once that is completed, turn Contacts back on. You will see a message “What would you like to do with existing local contacts on your iPhone?” Select “Keep on my iPhone”.

5. You will see another message “If you keep your current contacts on your iPhone, you may see duplicate entries. Are you sure you want to continue?” Select “Keep on my iPhone”. The reason you want to do this is that you may have created other contacts on your iPhone locally that are not in Exchange, so you don’t want to lose them.

6. Let the iPhone sync your contacts from Exchange. If you have a lot (I have almost 4,000), it will take some time (which is why I suggested being on WiFi). I suggest turning off your Auto-Lock (Settings/Display & Brightness/Auto-Lock/Never, then open the Contacts app (you’ll see the contacts populating) until all contacts are synced.

7. Then try creating a new Calendar item and type a location.

8. If you still see the problem, repeat the process with any other Accounts that have Contacts turned on (see Steps 1&2).


Let us know if this works for you.

After years of avoiding iCloud due to a general lack of trust in the security of cloud-based data, I decided to take the plunge. Approximately 2800 contacts and my calendar whizzed up to iCloud and I was looking forward to having my Outlook calendar and contacts syncing with my iPhone; and they did.


Then came the disappoinment. I tried to create on my iPhone (X with latest IOS) a calendar entry and as soon as I started typing in the Location box, a freeze for about 30 seconds occurred before any further characters typed would appear in the box.

I think the idea is for the app to scan contacts for matches, so that one can at a single keypress select the address of the contact required. I also think that if no match is forthcoming or it’s a preference to key in an address manually, one should be able to.


However, as many have discovered, typing anything in the location field is the kiss of death. It seems as though every location in the WORLD is then being searched. I have switched off ‘Location Suggestions’ in the Calendar application but the freeze persists. I’ve submitted a report to Apple but as we all know, once done, it’s up to them to fix it IF they deem it to be serious and widespread enough.


All we we can do is to apply pressure by further submissions and hope this is resolved. Right now, I’m going to have to revert to iTunes sync once a day with my iPhone and a paper copy.


What a state of affairs. Wake up Apple😮😮😮😮😮😮😮😮

Don’t take me wrong. That “solution” I discover it three weeks ago and I showed it in a screen sharing to a senior support tech.


That as we call it, is a band aid like the zz. It’s not a fix.


The same way that if you dictate with your your voice into the microphone, without turning the the contacts off, it type at the speed of light.


There is a beautiful calendar called Timepage by Moleskine the if you use that as a calendar, it doesn’t have a problem and it even syncs with the Apples calendar with the contacts on.


All this is fine. What is unforgivable is that number one, in almost two months and 8 updates they have not solved the problem and it’s us the users that we are solving the problems and number two, there was a jaibreak on the operating system 11.2.1 not even after 48 hours after its release.


Good luck and start considering migrating all your contacts and calendar either to Outlook or to Gmail.


It’s disheartening to see the such a great company that over 30 k engineers cannot solve the problem on the code they wrote.


And just to finish, my theory is that in the 1 million apps they have in the store and from the way we have migrated from Cloud to Cloud and OS to OS. And from IOS TO IOS, we have corrupted the cloud and the only way to solve it it try the millions of possibilities by enabling and disabling apps. Just like in OS 7, 8 and 9 you had to do with extensions.


Best of luck and buy another liver. I’m on my third demonstrating to over 30 techs, geniuses, seniors and whoever you can think the problem and the beauty of Timepage. It’s 4.99. It solves the problem. The interface can be a little difficult to learn in the beginning but the looks and the way it works it’s an absolute pleasure. That is the other option. Download Timepage and either continue to use Calendar or dictate your location.

Forgot to mention.


Today I’m working with 10 iPhone X’s and a few iPads where the glitch appears. Going to to do all the possible and logical tests. Interesting enough the glitch does not appear in iPods.


The problem, we think, is a problem of indexing and mapping along with the the fact that that nowadays most of the apps requiere and ask you for permission to use your location and send notifications.


My gut feeling is that by 6 or 7 pm we will probably have not be able to solve the problem because it is definitely an Apple Cloud problem that they have to recode the entire way they do it today as well as a a mapping problem that they created without ill intention but with not too much knowledge as of what the consequences would be.


I will try to keep you posted.


P.S. interesting enough, if you set your IOS DEVICES AS NEW, with ONLY AND ONLY THE apps the are Apple. AND NOTHING NOTHING NOTHING MORE. That is no other app, the problem does not appear.


As well when you go to general and try to do iPhone storage, you will see a delay and sometimes your system shows than you are using as much as 160gb. Yes you read right. Now I have down to 28gb which is also not normal.


Keep you posted.

The calendar is an integral part of the IOS and therefore can’t be deleted and reinstalled by itself.

Apple support had me do a full reinstall of the IOS yesterday on the iPhone 6s but it still locks up when you attempt to add a location to an event added to the calendar. Try adding a location in the location box under the event title using the letter “A” and if it is like my iPhone, it will lock up immediately.

I have now found this exact problem on two Ipad Airs and Air 2, as well as my 6s IPhone. If you add an event to your calendar and then try to type in a location, the calendar will lock up and has to be forced closed to clear. For example, try typing in “test” as an event and then try to add a location by typing any letter in the “location” box. All my devices will immediately lock up the calendar at this point. This situation started with the latest IOS incremental update as far as I can determine.

Apple support suggested I reinstall the operating system, but that did not correct the problem.
