Samsung Galaxy S3 LTE version contacts won't sync with my gmail account
I have got SGS3 LTE,,,,,my " Conctact to display " is from my gmail's account.
Recently happened whenever I tried to update contact's phone number ,,,,,what I used to do I press to the red line ( i.e minus sign) next to a mobile number to delete it and add a new number and then save.
My gmail's contacts on a pc gets updated with a new number and old one gets deleted ,,,,but when I check the contact on phone still I see the phone number that is supposed to be deleted it
Those options in the screen shoot below been ticked
How can I rectify this issue ?
