Keeps Resetting my mp3 players keeps resetting its self. and it does the sorting and stuf and that takes forever.it does like after i listen to it for 15 minutes.

You will need to plug into computer and restore through itunes.

look for a small pinhole on the device, and use a paperclip or needle to press the reset button inside the device.
doing this should reset the device and fix your problems

I would try resetting it by holding the menu and the center button at the same time and if that doesn't work try plugging it into the computer and then ejecting it after being charged of course!!!

Try resetting the unit.

Push the HOLD button in the direction of the arrow.

Press and hold down both the User button and the Power button for several seconds and then attempt to power the U3 back on.

If resetting the unit won't help, the player would require service. Call Samsung Customer Care at 1-800-SAMSUNG (1-800-726-7864). Have your model number and serial number on hand to set up service.

Try pressing the reset switch on the back....

As stated in several o the previous posts the battery was completly drained. I recharged for a full day and it woks fine.

Battery reset is the only method for resetting. Get the latest firmware upgrade from:

to prevent constant freezing

Send it back it should be under warranty

Reset, try again

This is the worst mp3 player ever invented - i have to tell you this up front. There is no driver, the company does not support the product anymore - I would return it now while you still can.

Either the device is bad, the pc port is bad, or the software is faulty. Try connecting to different usb port, then a usb port on a different pc with a compatible os. If still not recognized, then there is physical damage to player.

Try this: disconnect the player from the computer, turn it off, hold in the volume + button, and reconnect the player to the computer while holding the volume + button in. Keep holding the volume + button for an additional 5-50 seconds. Windows should eventually go into recovery mode and revive the player- it will pop up a window that says Found New Hardware Wizard.
