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.

I can no longer add a location after creating an event. Now that locks up as well. However I can copy from someplace else and paste. Or select from the Siri suggestions displayed. Using Siri dictation does not lock up the calendar, but it also doesn’t work. When you select what you’ve dictated it just does not populate the location field.

I went to the Apple store and they had numerous devices on 11.0.3 and none were displaying this issue. However, I have the same issue on my iPhone 6s and iPad Pro 12. I do not have the issue on my iPad Air. They are all on various iOS 11.0.2 or 3. Does not seem to occur right after an update. Something must trigger this particular glitch.

I think you actually mean it is still UNresolved with the latest 11.1 IOS update.

There was an earlier posting that listed a rather arduous solution of removing all contacts and doing a hard reset and adding back in your contacts, but that is too risky and time consuming to try, in my opinion. There should be a fix from Apple for it since it appears to be a bug.

I did try uninstalling and installing the calendar early on, but that had no effect.

Thanks for your suggestion, but I would urge readers to be a little careful with this fix. First, it did not work for me on an iPhone X.


Second, it created 4000 duplicate calendar entries on my iPhone. I believe I followed the instructions in this post correctly, but there is always a chance I did something wrong. Anyway, my contact list or no fairly gunned up.


I would recommend people to use the “ZZ“solution suggested by another reader

The last suggestion that an AppleCare advisor supervisor had to offer was to perform a factory restore on my iPhone 6 and reset it as a "New Phone" and use it like that for a few days. They told me that this was the next step; required it they were to continue to help me, so they could be sure it wasn't a "device" issue. Since I had read about everyone else's problems with the exact same problem, also after the iOS upgrade, I was not about to waste all that time and effort.

I guess we are at Apple's mercy.

Well, simpler getting through with Apple Calendar at all and use Google Calendar. At least it is reliable. I am sorry for Apple, but honestly I do not see any reason to use a workaround to use an app that they do not wish to fix when I have a valid alternative. By the way, Apple devices are robust and reliable but Apple software is always confusing me. In the iPad mail app there is no way to select a range of email for bulk deletion. You have to select each email one by one, or use another workaround to delete them all. iTunes is probably one of the worst software I ever used. I could speak for hours about wrong things in that software. The Clock and Calendar app are really poor. The Contact app is extremely limited in function, really primitive. There is no either a bulk edit of fields. But also this forum is really unreliable.

I just received the following email with the latest comment, since I subscribed this topic:

So I clicked on "go to the discussion" and I got this:

I repeated the operation on the laptop. Same result. I had to go directly on the post to add this comment!

I have the exact same problem. I enter the box for location and the app freezes. I have to save the event first so I don’t lose the person and time. Then I have to go back in and edit the event go into the location field and enter the first few letters i.e. Dr. .... and I have to wait literally for 15 minutes for it to unfreeze. I am using a brand new iPhone X. This does not occur on my new IPad Mini.


Why is this happening to so many people for such a long time. Same thing happened on my IPhone 6S.


Please advise. This cannot be considered a “business machine” with this flaw. Huge time waster.


Thank you,

Carlos

Thanks for this idea to fix my Calendar glitch, but it did not seem to work for me. I turned off the contacts but when I turned them back on it didn’t say anything about what I wanted to do with local contacts and I never saw it repopulating anything. I went back into my Calendar app and it continues to lock. Very frustrating since I missed my web meeting this morning because I couldn’t get the event to open in my calendar... aaargh. If anyone has other ideas, I’d be grateful!
