Hello, guyz! Since a few mounts i have a problem with my back speaker (for the music), so i fanally find time to share it with you. The problem is that when i play a song or video or when someone call me the volume ringtone for the 1 sec is ok, but then the volume goes fast down (i dont touch any buttons) or even sometimes there is no volume of the music… that really piss me off, so have someone the same problem or can anybody help me?
