To make life even more bizarre, I ran into another situation where camera.open()
worked in the sense that it didn't hang as in the previous example, but a following
camera.setParameters() did hang:

   Log.i("OIC", "JUNKcam5");                  
   try { camera.setParameters(parameters); }
   catch (Exception e) { Log.e("OIC", e.getMessage(), e); }
   Log.i("OIC", "JUNKcam6");        

then only gave as output

   JUNKcam5
   
In this case too, the built-in camera app would just hang with a black screen, and I
had to power off the phone to get back.

This issue is assigned to an engineer for further evaluation

Great. I still regularly run into this problem while developing my camera app, say
once or twice a day. It looks a bit like the camera does not always get released, and
once detached from a given app (when the app crashes or perhaps leaks some context
when it exits normally) no app can connect to it anymore, including my own app. I
still only know of the power cycle to get the camera back.

Could you attach the output of adb bugreport or at least adb logcat -v threadtime the
next time this happens? This'll assist with diagnosing the issue. Thanks.
