Q: Multiple Apps Freeze and Crash on iOS10

Some additional finding: The Settings app also crashes under iOS9

I just reproduced it on a friend's iPhone 6.

It also happens on iPhone 5 and 5s. Basically, every iPhone has this "feature"!

Everyone can try it:

Step 1: Open a *large* crash report file under:

Settings->Privacy->Diagnostic&Usage->Diagnostic&UsageData

pick one that starts with "stack+"

Step 2: Long press anywhere in the text to start selecting

Step 3: Quickly drag the end selector all the way to the bottom of the screen

The app should freeze now.

If it does not, try to scroll down and drag the selector a few more times, it will.

The phone is not frozen. You can still click the home button, switch to other apps.

Actually, if you wait for about 70 seconds, the app will unfreeze by itself.

If you switch away, or go to standby, the apple will crash.

Granted this is an obscure use case, but it may have some connection to the crash of some other apps.

The important thing is that it is *very reproducible*!

And it prevents me from sending the crash report to other people.

If we have some Apple people here, they should really take notes!!

Seem like my posts are not visible in the thread list?

Hello, can anyone see this?

There are at least 5 posts reporting this same problem:

"Phone" App keeps crashing under iOS10, reboot, reset do not help.

Apple, please tell me you are gonna fix it in 10.0.3!!!

There seems to be a solution at "Phone" app freeze on iOS 10

Here is what I learned:

Basically, you need to go to Settings->Mail->Accounts->...

to disable the syncing of "Contacts" from those accounts.

The biggest culprit is Exchange server and Hotmail accounts.

Gmail accounts can also be the cause.

iCloud account should be fine.

It seems iOS10 has problem syncing Contacts from some of those servers.
