For the past 2-3 days, earspeaker is very buzzy especially in high volume. But if I put the same call in loudspeaker, the call quality is good.
Perhaps you could visit the service again and tell them how things are.
Facing a similiar issue.. Ear speaker is very noisy and some times not working at all..
Submitted the phone to Local service center..
I feel bad for choosing Sony..:smileyplain:
Gave the Phone to Service center ref.# W115083104770.
Its been more than 10 days, but i didn't get my phone back.
Service center guys says that Phone has been sent to factory for repair works and they aren't replying back to them even after multiple follow ups.
And I tried with the Support Phone Number too, all they are saying is I will get a call back from Senior person.
No POC for escalation or nothing else. Any one can tell me wat should I do now ?? 
Its been exactly 3 months since I got this phone. I regret for choosing Sony.
Aug 28: Ear speaker got noisy and sound was breaking. Thought it was a signal problem
Aug 29: Same issue again. Gave it local service center (Tambaram, Chennai). They gave back after reinstalling the software.
Speaker was buzzy again. They said NW quality could be poor. They play one inbuilt sound with lowering the vloume. It was OK. So went back thinking to change sim.
Aug 30: Tested the call quality with other SIM card comparing the same in another phone. Voice is breaking frequently even when the volume is less than 50%. If I put the same call in loud speaker the sound is good. ISSUE CONFIRMED
Aug 31: Resubmitted the phone. After Demonstating the problem, they accepted and said will make a repair and return back my 3 -5 working days. (When asked about Standby phone, they simply said its currently unavailable) (Job W115083104770)
Sep 4: I Called local service center. Got the update as "Waiting for part". ETA 3-4 working days again
Sep 5; Tried Customer care chat support. I was asked to contact local service center
Sep 8: service center guys called me. Got the update as "Waiting for part". ETA 3-4 working days again
Sep 11: I Called local service center. Got the update as "Waiting for part". ETA 3-4 working days again
Sep 11: Called customer care. Got update as "Senior person from Sony will give a call back"
Sep 14: Sony Senior person called me and heard all my story. At last he said, "Waiting for part" and I will get a update from Regional Head office, on following day.
Sep 16: Service center guys called me. Got the update as "Waiting for part". ETA 1 hour upon receiving the part. When asked whther they received the part, No answer.
The sole reason which we prefer Sony over other brands is Quality and Service. But I dont think it doesn't make sense any more.
This phone is still available for Sale in India. But the parts for repair is not available yet.
Yes I regret for choosing Sony. 
P.S.: Dear Moderator, pls dont give the same steriotype answer to check with local support team or Regional customer care number. Tried all options. 
Ear speaker was not working properly after 2 months from purchase date.
Submitted my phone to local service center by August 31. (W115083104770)
But, didn't receive the phone back till now. When querying the service center, they r saying they didn't receive the spare parts yet.
Any help guys..?
