Special Remark:
If you want to play 2 YouTube videos simultaneously you need to mute the sound on YouTube website.
The mute button does't come up with startup. To display the mute button you need to rotate the phone between vertical and horizontal after YouTube videos are loaded. Sorry for the inconvenience.

Hope you enjoy the sport!
