hello all,
i have bought a samsung 5250 and i have a problem with the phone.
basically when someone is calling the phone does not show the caller's name even though i have them as contacts.
i have checked and i do not have two contacts with the same number and i only have the contacts on my sim card. i also tried to remove the country code from the contact but it still doesnt display their name when they call me. any ideas?
