I had a Razr which worked perfectly. My S4 can't seem to play music. I have done restarts and troubleshooting with Samsung, no helpl, new SD card 3 of them different manufacturers, no help. It will play some songs and only play 1-2 seconds of the rest. It is deffinately a phone issue and i am so sorry i got this S4 it is ridiculous. God Verizons rules on returns is so customer unfriendly, i am stuck with a piece of crap. does anyone out there know what to do to resolve this issue, i am so mad i could cry.
