You can give it a try but I don't think latest Walkman will work with 4.1.2
Sent from my MT11i using XDA Premium 4 mobile app
Album and Movies works fine.. but Walkman didn't work.. Moved to system/app.. after reboot, Walkman didn't show in app drawer..
Do you know link to last SemcPhotoEditor who work good with new SemcAlbum on CM11?
