a few other people seem to have this issue. no solution. just try positioning your mouth differently on the microphone and see. or turn off noise cancellation during the call.

Calls on Lapdock ?

Question for somebody who has actually handled a Lapdock: how do phone calls work? Will it make/receive calls with a bluetooth headset? If you do not have bluetooth active will it turn on the speakerphone? Or, do calls not work while on the Lapdock?
Oh, and if you are on the phone, will it still surf the web (wi-fi or otherwise)?
Okay, I can chime in with a few answers...
Phone calls without bluetooth headset - Yes it defaults to speaker phone and works great.
Using webtop while talking - If you're only on cdma you'll lose your internet connection however with either wimax or wifi on you'll still be able to surf in style. (Webtop speed doesn't to affected either)
I would guess that if you're using a bluetooth headset it's just connect with that as normal but I'm not 100% as I don't own a bluetooth headset to test it with.

Scratchy noise during calls.

Hi.
#PROBLEM 1:
Is someone experiecing some scratchy noise during calls? Looks like a blasted speaker. I noticed that on bottom speaker too. Is there a poor quality speakers or am I unlucky and got a damaged phone?
