The phrase "fiddle with" means to make small adjustments or changes to something in a playful, experimental, or seemingly aimless manner. You might fiddle with the buttons on your shirt, trying to make them lie flat, or fiddle with the settings on a computer to see if you can get it to work better. It's often used to describe a kind of tinkering or playful exploration, without a specific goal in mind.
