iPhone 6s - iOS 10 - Phone app crashes/freezes

Same problem, on iOS10.2.1. Dialer app freezes temporarily when making calls, causing me to have to redial several times. Very annoying and makes 6s unreliable.

I have to sync with work's Exchange server, so deleting non-Apple accounts is not an option. Reverting back to 9.x is also not an option.

For now, I've installed an alternate dialer app (Simple Dialer) and will see if this helps.

Seriously Apple... not good. Not good.

The Apple level 2 or 3 tech just disconnected from our call. I assume this since she didn't try to call me back. I have done everything under the sun to resolve this issue. They are saying my back up is corrupted. If that is the case than ios 10 did it because I didn't have any trouble before 10. Has anyone upgraded to the 7 and this issue resolved itself? My phone is my lifeline for my business and I cannot continue to have these issues. Please please let me know. Thanks! Heather

Try Reseting network settings and all settings in general > reset.

Hi bellefso

this case is probably a corrupt software file you can try to make one backup off device on iTunes following this article

If you can't update or restore your iPhone, iPad, or iPod touch

Before make iTune backup you can do this

If you can't update or restore your iPhone, iPad, or iPod touch

Best regards

Try force restart (by holding home and lock buttons together until Apple logo appears on the screen) and try to reset settings from settings -> general -> reset

If that did work most probably you'll need a full reset using iTunes but don't forget to backup your phone first

I have the same issue after the upgrade to ios 10 on my iphone 6. This could be a real problem if I find myself in an emergency situation and have to kill and restart the app to dial 911 etc....

I have the same problem as you describe. Wondering if it's a carrier issue. I'm on Verizon. Nothing seems to fix it but closing the app and refreshing it. Even then, if I change from Recent Calls to Voicemail, it freezes. I've seen a visual voicemail error that says, "Visual Voicemail isn't available." I can't listen to a voicemail if the internet connectivity wheel is spinning. Doesn't matter if it is Verizon LTE or wifi. The voicemail will simply close and be marked as new. If I am on Contacts, it will freeze and not scroll. Because of the internet connectivity issue, I was wondering if it might be a priority process problem in the os (i.e. the os is putting background connectivity as a priority for the processor over user commands in the interface) or if it is unique to the carrier's internet vs wifi connection priority process.

I opened a ticket with apple....no help, went to the apple store......no help

I got the usual "there is no problem" "apple doesn't have bugs like this" "these aren't the droids you're looking for" "apple is wonderful and have a nice day"

My ONLY option was to go back to 9.3.5 if I wanted a telephone I could depend on in a emergency ( of course apple hates that because there's less opportunity to spend money with them in the older code). I did it this weekend anyway

( actually it was pretty easy ) and surprise the problem went away, my phone works perfectly now. lesson learned, ignore the red dot and DO NOT upgrade unless you have to because apple NEVER admits a problem.

I too have the same issue and have had it since upgrading to iOS 10. I'm crossing my fingers hoping for an update to fix it, as there doesn't seem to be a real solution available yet.

Same phone app freezing issue here. Sometimes just closing and re-opening works, sometimes restarting the phone works but this happens at random and is hard to replicate on demand.

Using Rogers in Canada and running 10.0.2 on iPhone 6s

Ironic that the one app we need this phone for doesn't work....

I have the same problem but it freezes and crashes on all apps of my iPhone 6s (verizon). I am so frustrated!

Same here.

iPhone SE, upgraded to 10.1.

I'm from Poland, and phone was bought in store (not from cell operator) so I don't think it's carrier issue.

Same issue here on 6s with VZW.
