Not really. Are you on a leak? I have lost the ability to see pictures, and names for quite a while now. I am hoping an official OS will make it return to normal but I am running something close to the eventual release I believe and nothing seems to work.

If he are using a dummy sim than it won't show. Dummy means without proof sim

I too get this issue sometime on my Z3 but it gets around alright: after couple of hard boots.

Myself, I was never too keen on how different countries handles international dialing numbers or had different number formats. Personally I think each service should be assigned a number based on the IPv6 format. 16 alpha digits. Would be difficult at first to accommodate, but as there would be no end to the combinations it would make for easier formatting world wide.

That being said, OP:
Did your caller ID work before?
Did any changes to your device or service happen recently?
Do any caller IDs work now or are they ALL showing nothing?
Do you have Encryption enabled on the device by chance? (not that I think this has anything to do with it.)
