Hi Sony,
I have some weird problem with my Xperia U. If I receive a call while listening to music through earphone, phone will only vibrate. Nothing is heard through the earphone. After receiving the call, call timer display will come start after 4-5 seconds. Now, nothing is audible. I removed the earphone, then also loudspeaker both front and back is not working. After disconnecting the call, I played the music, but nothing is audible
I received a call without earphone plugged in, loudspeaker totally stopped working
Only way to set it right is to restart the phone!!!
Please let me know whether this is a software issue or hardware issue. If hardware issue, guide me to get a replacement. If software, fix it ASAP.
This should be fixed soon.
Please help!!!! 
Thanks,
Adi
After getting serviced at the sony service centre this was gone. Now there is a new problem for me that has come up. My Wifi is not working properly. This problem started when i was listening to music and browsing through internet through wifi, I got a message (SMS) notification and then Wifi went out.
Suprisingly headphone / speaker is working fine and there is no issue in answering call. BUT this new issue is now annoying it. Do I have to visit the service centre again ???
Have we made a mistake buying this handset????
try to add the wifi network manually or change the password and try again.
Do you think I would have put this message blindly without trying all options suggested here. I've already raised this issue in different thread.
All I am asking is this problem something to do with getting interrupted during listening to song with headphones
Do u think it is a good idea to show attitude to people trying to help you out?
Sorry.
I am sorry Arnab if you think that way... I only meant to say there are forums and discussion already available suggesting such options and I am done with that. My problem is not solved yet. Everybody is complaining here but not getting any solution.
When I got my problem solved I suggested that as well here.
I was just sharing my experience and did not mean to hurt any one 
mail me in details about ur wifi problem.
Adi even i had the same problem ... after updating to .184 its now resolved .. no more such problems even signal drops has be resolved .. update urs to .184 i ll be fine
...
Hmmm... Mine is .184, have updated soon I received it
long time now...
There is some other problem, which Sony failed to solve or may not discovered [afterall, they dont test their products/builds, just assuming]. 
hi shubham chandani May i know about the software version of your phone
