Hi I gave recently got a moto g and realised the album covers when I'm listening to music and really zoomed in and doesn't display the full album cover. Does anyone know how to fix this never had this problem in iPhone or windows

It must be the way the images are saved to the file and likely doesn't have a way to fix that. What type of audio files?
