Hi yah. I have a question before planning to buy this Z1, my recent phone is Xperia Z, and im disappointed by its loudspeaker.
How's the Z1 speaker have been so far? are there any improvements?
Your response would be greatly appreciated. thank you 
I do't expect the loud speaker to be a lot different than the Xperia Z or Z Ultra
It's much louder as i've gathered from this comparison on youtube https://www.youtube.com/watch?v=kXydSEFLaKs when you have time you can check it out.
it will be interesting to compare the loud speaker with the X10, Xperia Arc, Xperia S, Xperia T and of course Xperia Z and Z1
All Sony's flagship phones.
My speaker is not very loud . Any ideas or apps ?
It might be a hardware limitation
To increase the sound from the internal speaker a bit more you can enable xLOUD under Settings -> Sound -> Sound effects -> Sound enhancements -> Settings.
haven't heard Z so cannot compare but with my poor hearing Z1 sounds loud enough; not sure what do you expect but I can hear speach and music quite fine. Of course, if you are expecting sound of a propert speaker, I haven't heard that from any of teh phones; so far, compared to 3-4 different phones I had, Z1 sounds OK and loud enough; why not pop down to any phone shop and compare with your phone?
yup it's at least 50% louder than both the Z and ZU
@GeoffH too bad you don't have an Xperia Arc to compare it with, as I think its one of the loudest Xperias.
