Just brought this phone 2 days ago, 1st had to instantly have a replacement becuase the back case didn't fit on properly..
So just got it home, looks good, screen quality is good, camera is good for considering it's 5mp,
however, the speaker is so pathetic! i'm playing music full volume and can literally whisper louder.. whats the hell!? i'm really gutted i've just shelled out on this because i always have music on in my room or shower and out and it's embarassingly quiet, your telling me that all the money sony makes which must be billions and they can't design a decent speaker. what a joke, my sister has the xperia s and the speaker on that 1 is better, but my old phone the htc wildfire which is about 2 years or more old is way louder and better, i thought technology would have advanced by then..
will there be anyway to upgrade the speaker!!?? If not i'm gonna have to try and beg a refund becuase i'm not sure phones4u will let me 
what a dissapointment!
the part that was *** out wasn't a swear by the way, it was h e l l
Hello louiebg
Do you have xLOUD™ activated?
Settings> sound> xLOUD (activate the checkmark)
Let me know what happens with the function active.
Best regards.

I hope it don't make the sound distorted!!
Yeah i've put that on and it is slightly louder at the cost of crackly horriible quailty.. 
Just as I guessed!! Get to service center and get your handset checked!! Sorry for bad experience at sony!!
I would like you to compare this unit to other Xperia U's.
I'm thinking that there may be a physical problem with the speaker.
If so you will need to send it in for evaluation.
Francis.
Its BRAND new though!?
Its brand new though, just fresh out of the box.. surely 2 in a row cant be faulty..
And i dont particularly want to send it in becuase i want to use my new phone! but its not even a happy moment, and also i dont want to be without a phone for however long you guys have it (probably weeks) and i bet it costs me to send it off to fix your problem too?
Yes! Francis is right! Some models have problem even when you buy them recently, those are fault from the factory!! You might want to have it checked by an authorized personnel!!
