iOS 10 Black Screen Spinning Wheel

I Solved it by resetting all settings. all my apps work including outlook and other apps mentioned on this post.

mmansour's supposed fix does not work for me.

This has happened to me 10-15 times TODAY...how is there not an update from Apple that addresses the issue?

Outlook seems to have been the culprit for me. I removed it and went back to stock Mail. The issue, which was spinning wheel then lock screen occurring 10-20 times per day, disappeared immediately.

I also have Outlook installed on my phone and iPad. This condition happens on both devices. I'm going to remove it from my phone to see if this helps

I Have outlook installed as well. So frustrating as I had NO issues on iOS 9. It seems stability was traded for XL emojis in the messaging app. Less than impressed.

So I think it is possible that Outlook increases the likelihood/prevalence of these crashes and spinner problems, but the problem is definitely deeper in iOS since folks who have never installed Outlook are also seeing this. Also, the worst an app being unreliable should be able to do is crash itself, not the entire shell of the OS.

TL;DR: iOS has a nasty memory management / sandboxing problem that Outlook (& maybe other apps too) makes really obvious.

I Have this exact same issue on my 2 week old iPhone 7plus and previously on my 6 before I traded up. Black screen few seconds with circle then asks for my security passcode. It crashes usually in apps from FB, imessage, safari, and snap chat... but ive favtory reset a few times, today I reset and set it up as a new phone but still happening. one time it crashed and I had to bring it to the Apple Store for them to reset because iTunes couldn't even help me recover it. It's frustrating. if anybody gets any answers please let me know !

I've also noticed that my volume CONSTANTLY resets to about 75% loudness. I think this happens after the crash. Do you know how annoying it is to be in bed, catching up on current events only to have a video start playing at 75% volume??

Is anyone else experiencing the volume change back to 75%?

Just for my own education: do you have Outlook installed on your iPhone? Because like others have mentioned before, I haven't had a single issue with iOS 10 since I deleted the app. Before that, I also got 5 to 10 crashes per day...

I Have outlook on my phone (but notifications disabled) and had no crashes, i fixed it by resetting all settings Which removed all apps notificationS. This problem seems like unusual, would a notification cause these OS crashes? But why would a notification cause the whole OS to crash.

So I removed Outlook from my phone and everything has been good so far. However, I'm still seeing crashing on my iPad. I checked the logs and saw some references to the Agenda Widget.

I'm not sure if this has anything to do with the issue at hand but wanted to share.

I found the same issues with my IPhone 6 , the bigger issue was I plugged it in at night to charge and when I woke up and unplugged it the screen was black and never came back on I did everything apple told me to do and the screen doesn't come back , but when plugged in shows its recovery mode on Itunes

Hmm, so maybe the problem, then, is widgets in iOS 10 having memory leaks, and the Outlook app's widget is particularly unreliable and prone to causing the system crashes folks are seeing? And for those who don't have Outlook installed but are still seeing the crashes, then maybe they have a bunch of widgets configured that also expose this unreliability in iOS 10?

I need the Outlook app for work, so uninstalling it is not an option for me, unfortunately.

I have disabled ALL widgets except for a couple native Apple ones (Phone Favorites & Weather) to see if this improves things for me.

iPhone 7+ owner here for the last couple weeks, have also been experiencing this exact same issue (crash to lock screen after black screen + spinning circle for a few seconds) So far the most trouble I have had has been when trying to take a picture, be it from the stock apple camera app, to using the stock notes app and adding a picture, or trying to take a picture with imessage, telegram or snapchat. I too use the Outlook app for work but have actually never seen that cause the crash to lock screen. My wife has an iPhone 6S running iOS 10.0.2, takes loads of pictures a day as she sells online and has not once experienced this issue.. Frustrating indeed!

I'm having the same issue. I've had this iphone 6 for over a year with no problems. I updated probably a month ago, still no problems...until this morning. Checked the weather and since then (over an hour) have the black screen/spinning circle. Does not shut down with power/volume and I do not have outlook installed. This is aggravating.
