Random iPhone crashes and reboot loop after iOS 7 upgrade

So... in our case, we have reoccuring meetings scheduled several times a month. Apple said that possibly one of the contacts that are invited to the meeting have a space somewhere in there name where it shouldn't be and is causing the system to freak out when the reminder for the meeting pops up... example FirstName LastName , Title instead of FirstName LastName, Title. So, do you have any reoccurrning meetings or alarms on your phone? I'd say turn any and all of them off and see if it happens again or not. It's obviously something to do with an event that's occrruing at the same time every friday.

@crystalmarie_82 thank you for the insight today.

I tried something new today to test cause/effect and it worked. I disabled my gmail calendar on the iPhone via the mail, calendar & contacts settings about 30min before the time today the phone has gone into it's re-spring crash cycle every other Friday since upgrading (about 215p). Lo and behold no crashes. I turned the calendar back on at 330p and no problems. So phone stayed almost fully usable today (no calendar for 60min) for the first Friday since upgrading

I also recognized that my gmail calendar is syncing with my corporate exchange calendar via a google sync app on my corporate laptop. I'm now suspect something from the corporate calendar gets sync'd accross to gmail causing the crash. The weird thing is I do not have any recurring meetings on Friday afternoon near the time of the weekly crash cycle.

Getting closer. Thanks again for the insights as I now have a mitigation strategy if needed to keep phone operating on Friday afternoons till I figure out the permanant fix.

Pls when you took your phone back to the store did they require the pack. I have the same problem but discarded the pack

No they did not require package/box. I mean, I did not even realize that the problem would require a brand new phone.

Here's the latest. I thought I had this issue resolved by deleting a particular calendar entry that had a few dozen attendees listed. Given it was my only recurring item every Friday (when the crashes occured) I was taking a guess it was the culprit with some element of the causal criteria outlined by @crystalmarie_82. After deleting it I went two Friday's with no crashes and thought I was out of the woods.

Well, I got ahead of myself. Today at about 1135a the reboot (respring) cycling recurred. As today is a Monday it's clear there are other causes; maybe a different or new calendar entry. I did have a new recurring event start this morning at about the same time as the crashes. Speculating that was the casue this time, but have only circumstantial evidence for that at this point. For the second time the crashing actually started while I was on a call. When that happens the call audio drops in and out, but the call does not drop completely. So it's clearly not a reboot, but a respring.

I'm now waiting for the phone to return from pumpkin land after being left off for a few hours. In the mean time I've completely deleted the gmail calendar that I think is the culprit. That is the one I use to sync my corporate calendar using google sync pc client. Not sure what I'm going to do about syncing it to the phone or not going forward. For now I'm going to leave it off and see how it goes. Really frustrating that this bug is in there making a key function of the phone unusable.

you have been a great help. just the fact that i know im not alone is a big relief. but so far nothing has changed. ive had to reformat and re install the back up 3 times in the last 5 days. it is still currently going on a reboot loop. now it seems to happen more when i've lock the phone and set it aside compared to before my 3 reformats where it can just totally crash and start a boot loop all by itself while im using it, in the middle of a call, using an app, gaming... etc

does the apple team really not know what going on? i suspect its because of the new 7.0.4 patch.

so whats the latest guys? any luck?

Update

Since deleting the suspect gmail calendar from the phone the crashing has not recurred. Clearly something in that calendar was the cause. Quite frustating as it worked for almost two years without issue until the iOS 7 upgrade. At this point I'm stuck carrying two devices again (Blackberry for email & calendar and iPhone for all else since Blackberry is basically useless for more than the basics) since I can't sync my corporate calendar to my iPhone via gmail as I'd been doing.

Good news is my company is moving to iPhone as standard issue in Feb or March. I'm hoping the 5s they provide me will be wihtout this issue as it wil be able to sync directly with the exchange server.

Hello everyone.

1 hour ago, i was thinking of selling my ipad 3. the reason was long reboot time and some crashes i was experiencing.

yesterday i thought that these issues were caused by iOS 7. I' ve tried every method: clean install, reinstall, restore, hard reset etc etc... None of these fixed the reboot loop and random reboot issues. For example, while using safari, or using some apple app like Keynote, Pages etc, first the screen gets strange, some blurrings, stripes and freezes occur. then iPad does not respond to my actions and reboots. reboot time usually varies between 1 min - 30 min.

So I' ve decided to take a look at diagnostics. most of the errors were originated from springboard. There were panic.plist, etc. etc. among them and there were hundreds of error reports.

And worst of all after using the new restore a few days, again in a bootloop, it fails to boot and shows "connect to itunes" logo.

All the information i collected from web pointed that it was a hardware issue. But some were suggesting it was due ios 7.

So i thought it was worth a shot. Did my UDID register and installed ios 7.1 beta 3.

And Voila! it enters in bootloop again 🙂 but looks kinda more stable. But haven' t stressed enough yet. i will keep you people updated.

so why i told all of these? as i said, i was thinking of selling my ipad 3, because it has gotten really annoying and i was thinking it was only me encountering this issue. And then i saw this thread and realized i was not the only one. That's a relief. It looks like a software problem (I hope).

Called support and this is a known issue. If you get the fruit-loop-of-death check to see if the display name of the user (in a calendar invite) contains a comma inbetween two spaces. This is in reference to ActiveSync on iPhone and MS Exchange.

Anyone know if iOS 7.0.6 rolls out a fix for this issue?

I think it will be 7.1 and we tested it and it seems to have solved the issue. I am not a 100% sure. But if you have this issue Apple says that you can turn off the notifications on the phone and it should be fine - unless you rely on notifications.

So I know have native exhcnage sync going with my iPhone and coporate server. Can you be more specific about how to "turn off notifications?" I've tried turing off every form of notification I could find for the calendar and I'm still having the same issues. Only thing I can find that fixes it is to turn off the caledar entirely. Not a very good solution as I need to be able to review and add/delete items from teh calendar while mobile.

Thanks,

Jeff
