Xperia z3 aux output

[karan30]

Hi I'm using an Xperia z3 and when I was using my phone with a speaker using the aux cable the output volume was very less compared to my friends iPhone on the same speaker...I tried changing the settings to increase the volume but it didn't help...can some tell me what should I do to get the same output as the other phones...

It doesn't seem to be possible, but contact xperia support to see if there is something they can do.
