Click the home button to turn the phone on and off. Click the music note to go to the music app. Once in the music app click on the name of the song you want. There will be a button to restart the song, stop the song and go to the phone's home screen. Just click these buttons. There will be a battery sprite that will go down in power every 15 seconds. Click the charge button to re-charge the phone battery. This is a simulation of a Samsung galaxy s7.
I got the music from Artrobot 81, Chumpy 50, and cotto4040.
