I'm guessing they passed on the widget because of how the music player is incorporated into Touchwiz. The drop-down bar and lockscreen have the equivalent of the widget, and I actually like how they incorporated this. You can access it much easier without having to go to your homescreen where the widget is.
I use G Music Bata also . I do like how the stock player has sound and EQ settings build in. wish it would work on GMB player. Or GMB would incorporate an EQ into their player. I like having my SD card space free. this was thers no need to go out and get a 32gb card... YET... lol
Samsung just neglected it - figuring that we would select a different APP. Not sure if this is just the USA market but it is NOT good! Has anyone found a better selection than reverting to an original phone model?
