How to duplicate photo on iphone IOS 13.1.3 ?

Noticed same issue just figured it out. Click on the little box with an arrow bottom left corner of the picture, then it brings up some options. You have to then pull the screen up, and it gives you more options including the duplicate button. See Attached pic

Hi there, when you click on a photo in your photo album, there should be four icons below, press the one all the way on the left that is a square with an arrow on it, then scroll down a little until you see the button that says duplicate, press that to duplicate a photo. I hope that correctly answered your question.

Hi again, Hmm.. that’s strange, what iOS device are you using to duplicate a photo?
