I think it caused by mozilla bug 987022.

Investigating.

Music app was interrupted and killed by LMK after step 3 in comment 0, so we shouldn't restore the music app after the call ends because the video app already interrupted the music, and my patch should fix it.

triage: 1.3T+ to fix a corner case in the new implementation

Dkuo, seems like you are working on it, do you mind taking? thanks

Comment on attachment 8410074 [details] patch Alive, This is an issue caused by bug 987022 on 1.3t, my patch didn't consider the scenario that music app is killed before the incoming call comes, but the fix is simple, just let the last play status to be STOPPED then the media agent would think music app is not playing so it won't re-launch it, would you please review this patch? thanks.

Thanks Alive! 1.3t: 706f474230432c8cb01e124aee2c055ec902aa1d
