I bought SP very recently. To my bad luck I am facing problem of low ear speaker volume and too noisy. Microphone. So that neither I can hear the other party loudly nor the other Party can hear my voice clearly..I have done factory reset repair using Sony pc companion... Nothing changed. Then I took the device to service centre where they said it's The problem with faulty Speaker and they have replaced the same. Still the same problem Persists. I am blank. Please. Help
