Hi, I usually use my tablet when I practice and take lessons on guitar tricks. During the video on the left side of the video, it gives me the option to slow down the play to the speed that I like. When the battery dies on my tablet I move to my Android phone and find that I don't have the option there to slow down the video play. Anyone else have that experience? Of course I try to only use my tablet but once in a while I forget to charge it in time
