[android-developers] Re: Autofocus callback not happening on HTC Desire HD

Hi Marco,

I've been dealing with other issues with the HTC Desire HD myself.
For instance, the Camera.getHorizontalViewAngle, and
Camera.getFocalLength return -1 instead of proper lens values. I've
already informed HTC about the issue, but I think its fallen on deaf
ears there. I think HTC was sloppy with the Android integration on
that device.

Sorry I can't help your particular issue.

Best,
Stephen Lebed
