You2MP3 Player Watch YouTube videos on screen and listen to MP3 audio in the background when the device lock-in sleep mode. Switch between YouTube Video to MP3 music automatically. During incoming / outgoing calls, the application automatically pauses the video, and upon completion of the call, the application automatically continues to play from the moment it was paused.
You no longer need to continue manually each time your smartphone accepts incoming calls or when the app switching to another program. When the application is inactive, the audio track starts to play automatically. When the application is active again, instead of the audio track, continue to play the video track from the audio track playing position.
