I use the smart watch to see what's the hour. I use the camera to take photos and record videos. I use the microphone to record my voice or talk louder, in front of people. I use the headphone to hear better or so I can hear just myself. I use the TV to watch shows or movies. I use the phone box to call someone or receive a call from someone. I use the USB cable to transfer files to another device. Sper că e corect
