iphone 6 - restart screen with apple logo randomly appears during phone calls

I Have exactly the same thing happening On my new iphone6

it happened on the latest release of iOS.

Updated to IOS 8.1 and still have the same issue. Maybe it's a sign that I talk too much.

I Am having the exact same problem .. I hope iPhone support staff will take this to their consideration

I have exactly the same problem.

Has any of you been able to resolve this issue? It's impossible to use the phone this way!!

I too have this issue despite updating to 8.1.1

Other than these i have experienced the following priblems as well.

1)unable to answer a call. Only the red "end call" is seen on the screen.

2) after completing a call, the screen takes ages to return to phone menu. When i press the home button I can see the green call in progress notification on top.

3) momentery black out. No button works and the screen is dead. Only a forced restart by simultaneously pressung the home and sleep button, returns the phone to normal.

4)Wifi issues with my retina mini.

issues 1 &2 along with the main issue of apple logo during calls,was only noticed when connected to headphon

I thought apple will fix this with new update. IOS is still rewuires a lot of debugging. Apple really needs to sort these.

I Was jailbroken my iphone 5s using pangu(ios8.1) i also had this problem so i did un jailbrak... still i am getting this problem

Exact same problem.

Same exact problem here with iPhone 5c iOS 8.1 and it's driving me nuts. I use my phone all day for conference calls, I work from home, and it's really become a nuisance.

Any help would be much appreciated.

Thanks

This issue has only just started happening to me (iPhone 6; iOS 8.1.2), also on long conference calls. I'm on WebEx - is that a common link?
