While in the camera, the scroll wheel use to change the type of picture (video, contact, gps photo....) The wheel does not change the type of picture with the fixed camera. I jumped on XDA in October and no one has attempted a fix that I know about since I've been here.
I recently downgraded the camera, as a test, because it has been so long since I was able to use the scroll wheel to change type of picture. The version 4 of the HTC Camera definitely utilizes the scroll wheel to change picture type. I wish it were something as simple as a regedit to make it work as it did.
