I have Sony Ericsson Experia Arc purchased few moths back. Till today evening, it was working fine but now, I am facing problem with its speaker. Sound is not coming from its speaker. No phone sound, music games and even alerts. I haven't dropped it since its purchase. Torubleshooting: Restarted.... Given soft & factory reset, but no luck. Sound is coming fine while making calls, both ways. It is even giving proper sound with headsets but sound is not coming from speakers. Please help me what to do. I want to make every effort before taking it to Service Center. PLEASE HELP!!
