Default [Q] Photo editor - how to select and fill?

Ive looked everywhere in the editor and just about everywhere on the phone but i just cant find the option in the photo editor to select part of a photo and fill. Example: there's a blemish on something in the photo so you hit the select tool, trace around it, and then it cuts it away and fills it with its surroundings.

I have just bought the NOTE 3 and SGS5 and i swear ive done it on one of the 2 phones in the first days that i had them but now i cant find it in ether phone!

Can someone help

Many thanks.
