Phone no longer shows caller ID

[William Mjema]

My phone has recently stopped showing caller IDs, just shows caller's number. What is the remedy for this?

This has happened to my fathers 920, and for him it helped to simply restart it

Thanks, it worked, but I am wondering how often will I have to restart the phone?
