When I search for a contacts in my Mini Galaxy I find that many names I have previously saved and used by selecting them for calls are apparently not now in the memory. A name that I recently saved for a second time was yet again not there, so I did a search in the recent calls list. In this list appear mobile numbers without their contact names tagged, and I couldn't identify them. They should all belong to my named contacts. In order to try and find the last call I made to my contact I searched for a specific date when I knew I had used the phonebook to call my contact. The calls around that date were again without name, only numbers. Then I saw before my very eyes another name dissolving away and being replaced by its number! On searching for that other contact, it was not there in the phonebook. Had it not been for this weird vanishing act before my eyes I would have started to believe that my memory was at fault and not the phone. Can anyone please explain this occurrence? Is it a known bug? I cannot find any such reference in this site. Help would be appreciated, because it makes the mobile pretty useless without this nasty fault being corrected.
