Phones act as actuators too.

Actuation means turning electrical energy into a physical action that affects the real world. A phone does this through built‑in actuators: the vibration motor provides tactile feedback, the speaker emits sound, and even the flash or screen actions can create physical or perceptible effects. Because these outputs are physical actions driven by electronics, a phone can act as an actuator in an IoT sense, not just a sensor or controller. So saying phones act as actuators is correct, since they produce real-world effects in response to signals or commands.
