Lumia 800- country code (e.g. +852, +86) cannot be recognized after upgraded to 7.8

After upgraded to 7.8, i found that the phone call with country code cannot be recognized. 


For example, a contact "John" with number : +852-999999 is saved in contact. 

In before, no matter the incoming number is 999999 or +852-999999 or +86 999999, it can still be recognized. 

(the phone can smartly determine which part is the country code)


however, after upgraded to 7.8, it cannot be recognized anymore. 

Vice versa, if I save 999999 for John in the contact, if i am overseas and receiving the call e.g. +86-999999

it will show "unknown" because +86-999999 is not saved in contact. 


I have tried the same sim card on another WP7 phone, iOS phone and android, it is normal (same as what i use before)



This is very annoying. 

This problem is never found before upgrade. 


If anyone have idea, please feel free to advice. 


Thank you
