Open Google Now or the Google app on your phone. Either say Ok Google or tap the microphone to speak, or tap in the text field to begin your query
Tell Google about a contact and their relationship to you. For example, ‘Olawunmi is my mum’, or ‘Ugo is my boyfriend’If you have more than one contact to which this relationship may apply, Google will ask you to select which one you mean – just tap on it. To save your contact with that nickname, tap on the tick in a blue circle and Google will confirm that the nickname has been added
To later remove that nickname, follow the above process but this time say ‘Ugo is not my boyfriend’. Google will ask whether you want to remove the nickname; if you do, tap the blue tick icon.
