Here's how to remove a contact from your favorites list on a Samsung Galaxy A53:

Open the Contacts app.

Locate the contact you wish to remove from favorites. You might find them in the Favorites section at the top of your contact list or you can search for them in your general contacts.

Tap on the contact to open their details.

Look for the star icon, which indicates they are a favorite contact. This icon will likely be filled in (e.g., yellow or blue), according to LG Electronics.

Tap the star icon to unmark them as a favorite. This will likely make the star appear hollow or white, indicating they are no longer a favorite.

The icon is not filled in

I tried deleting the contact but not the messages as i currently need those amd it hasnt worked. Ive changed the name and everything amd it still pops up like that

Didn't need to delete any messages in the profile is there a star icon showing

The star is just an outline. I clicked it to make sure and then un-clicked it
