Caller ID problem...

[Sage15]

I have an problem with my Xperia M. When i make outgoing calls, the contact name of the person i am calling suddenly changes to "UNKNOWN" as soon as they answer. This satrted happening after i updated the software to the new Android 4.3 Jelly Bean. I aslo had the same experience with my Xperia Z after i had updated it. 

Is this a bug that comes with the new Android 4.3 Jelly Bean and has anyone else had the same problem? I hope Sony will correct this issue soon because it is annoying.

I've seen this issue with my Xperia Z1 and Z but only when I check the call logs

Confirm the same bug with XM Dual 2005 with JB 4.3

This is wierd as some calls are properly displayed caller name and some not.

This is even moer intriguing as at least called number should stay if there is no entry in phonebook

Yep, same here.
