When attending a R4 event, be part of the show by using R4 2020 Light Show when prompted. Your phone becomes part of the light show while you can still take pictures and video to share with the world. When big things happen, you will receive notifications so you and your phone become part of the celebration! During awards, during celebrations, during all events, you can become a part of it all like never before!
