iOS 9 phone app freeze

Thanks Elbert. We removed the sim and reloaded it after switching it off and the problem was solved. We still are facing the issue that the front camera does not work. It shows a blurred image and then goes back to the back camera.

I reset my phone to factory settings and after that I've done what il Santi said. but the problem didn't solve. phone app is still being freeze after some hours..

😠

just assume that you need to call to someone quickly or you are in emergency ...!!!

Why apple doesn't do any thing about this baaaad bug .....

"This helped me" star click not working, so I'll just reply that taking out the SIM did indeed help. Deleted call history while it was out. Seems to keep working now that it is back in. Thanks. -Gord

It was the Voicemail app for me. Finally got into it and deleted all the voicemail, works fine now.

My guess is that it would timeout phoning home to my carrier. t-mobile.

Use the Contacts app rather then the phone app.

I had this problem too. I didnt try to remove my SIM but I did try to reset settings, restore from iTunes (a couple of times) and twice from iCloud backup as well. Nothing seemed to fix my problem. Then I tried something different. My Phone app was syncing contacts from iCloud, gmail (because I had android before) and a few of my official email accounts. I figured I needed only iCloud and gmail so I turned the other contacts off. It fixed my problem straight away. No more freezing of the phone app. Hope this helps.

P.S: I am using iOS 10.0.2 on iPhone 6S

If anyone else has this problem, I went to settings>contacts>Accounts>outlook and removed contacts from syncing and deleted them from my phone, restarted the phone and I have had no problems. Something is probably corrupt with outlook syncing.
