I just got a Samsung galaxy s3 today as an Xmas gift. The sounds worked at first but all of a sudden the speakers stopped working. I tried playing a song but no sound came out. I plugged in headphones and i could hear the music fine. my dad put a screen protector on it and he may have gotten some of the liquid stuff you use to get the protector to stick on the phone. i havent dropped it or anything. any idea what the problem could be?
