How do I unhide a hidden photo album on iPhone?

I'm not sure either. Can you give us some more information? Where on your iPad do you see this "hidden album?" Is this in Photos or in Files or somewhere else? How do you know it's hidden? Or what makes you think that there is a hidden album to be found?

Have you looked in Utilities>Hidden and in Utilities>Recently Deleted?

Utilities is usually at the bottom of the screen. If it isn't there, check with Customize…
