improve call quality

[#1]

My X10 is just one day old.If not anything I was hoping the call quality be good. The voice of the person on the other end is horrible, i previously had a balckberry pearl, I checked the website for factors wchich cause bad call quality.

Even though my signal strenght is good, charge is full , the call volume is less, the other person is not in an elevator , not using any bluetooth or microphone or not using the speaker mode, the call quality si still bad.Has anybody faced this?. Did I get the wrong peice.Please help.Will  android update fix this?.I dunnoh what else to do.

Regards

This is a well known problem on the Xperia X10, but the phone does has a 'sweet spot' which, if found, will improve the volume of the call. It takes a bit of fiddling with the phone to find the sweet spot, but I found it on mine and did find an improvement Alternatively you could use the earphones or a bluetooth headset
