Ive reset it a few times and it will work for a little while resentley it froze when playing music.stopping the music and freezing the screen.i reset it but now its just on the white screen. Ive plugged it in to charge.white screen still and tried plugging it in to my computer/laptop and it cant be found.i only got this January this year as a present. So its not too old. But its making my life difficult and my other half feel bad for getting me when its not working.
