While it may be too early to tell if this will be a permanent feature, evidently in the Mango SDK emulator, the camera app now remembers what flash settings you've chosen. According to reader Amit:
"Playing around with the emulator. Discovered that if you change the flash setting of the camera it will actually persist now!"
Sure, it's not (yet) remembering all of your settings, but between being able to control your flash's behavior and disabling the shutter sound, well heck, we're willing to meet Microsoft half way. (We never use the flash except on the HTC Mozart with a xenon flash or on the Arrive, which is just well balanced).
Plus you Focus owners now have image stabilization by default with NoDo, so double bonus for you.
Thanks, Amit, for finding this!
