User taps Music App and selects music to play. User scrolls the circular button to move to a certain area of the music track (i.e. the 20 second mark of a 30 second song). However, when the user moves the circular button and taps primarily the pause button in a fast manner, the pause button appears illuminated but the music continues. The repro rate is very low (20 percent) and even lower when user executes the same above steps and quickly taps the fast forward button (0 percent) or the fast rewind button (5 percent). However, despite low rate of reproduction, it is concerning and presents an unfavorable user interface. See video and fast forward to the 43 second mark to witness behavior.

Repro Steps:
1) Updated Tarako to BuildID: 20140422014001
2) Tap Music App and select a song to play
3) While song plays, scroll the circular button to advance to a particular area of the song then quickly tap the Pause button to pause the song

Intermittently, song continues to play, pause button is illuminated in blue and doesn't stop unless user taps the button again.

Song pauses, play button appears where pause button once was, and there is no illumination 100 percent of the time.

Repro rate: Pause/Play button 20 percent (20/100) Fast Rewind button 5 percent (5/100) Fast forward button 0 percent (0/100).

This issue does not reproduce on 1.3 Buri. Following the STR in Comment 0 does not display the intermittent behavior of illumination of user controls and music not pausing when selected.

I don't see this anymore, and it's on Tarako, so closing this.
