Hey. I am having a major problem with the sound on my galaxy s. The ringtone and notification both work but i occassionally have to put it on loudspeaker to speak to people. Also when i am using an app, watching a film or listening to music there is no sound from the loudspeaker. When i try to plug the headphones in it completelt freezes my phone and when i remove them again the film or music starts playing again...still with no sound. I have tried doing a soft and hard cell reset and using other ussd codes. Definately not the hardware as my phone rings when someone calls. Please help
