Pushing smartphone side buttons

Boogami:
Hello,
I want to push buttons on the side of the phone (volume buttons, power button) using some sort of actuator. I've tested a small open frame push solenoid at 12V but it doesn't have the necessary force to push the buttons. Do you know any solution that can do this thing? Also I am thinking about using a micro servo but I want something that doesn't make so much noise.  ;D  Thank you.

Sure, servo with a cam would work.  Not much noise IMO.

I assume you can't modify the phone? Otherwise you could attach your inputs directly to the button pads.

Um... bigger solenoid?

Seriously, how much force and travel do you need? Because some solenoids I have used would crush your phone easily.

Yes, that is true. The phone is fixed on a surface and I want to mechanically interact with the buttons. Model of the phone can be changed so I can't modify the phone.
