Create a series of images featuring various hand gestures interacting with a generic smartphone. Use diverse skin tones for the hands and varying positions: 

1. A hand holding a phone at eye level.
2. A hand swiping on the screen.
3. A hand adjusting the phone angle.
4. A hand resting the phone on a surface with fingers pressing the screen.
5. A hand holding the phone horizontally with a finger pointing at the screen.
6. A hand holding the phone vertically in a relaxed position.
7. Two hands together, one tapping while the other stabilizes the phone.
8. A close-up of a hand gripping the edge of the phone with a finger hovering over the screen.

Ensure all images maintain a clean, minimalistic background to accentuate the actions. No brand logos or specific phone designs should be visible.
