For mako, flash turned on all the time(when forced flash ON) but the image was darker than the pic without flash, and when it got normal pic I could see this log often (seems more like post image processing)

Need to dive into mako code but when I touch the screen to make af work with flash in advance, then I could get normal pic all the time.

Title:
  pictures taken with flash are almost completely black

Status in Camera App:
  Invalid
Status in the base for Ubuntu mobile products:
  New
Status in android package in Ubuntu:

Bug description:
  On the mako / Nexus 4, the camera has an LED to use for camera flash.
  Our camera app supports the flash, and fires it while taking a picture
  with flash enabled.  However, the resulting image ends up severely
  underexposed, to the point where almost the entire image is black.

  Steps to reproduce:
  1. Run the camera app.
  2. Take a picture with flash off.
  3. Turn the flash setting on and take a picture of the same scene again.
  4. Go to the gallery app to view the results.

  Expected results:  The picture with flash should appear brighter (or,
  at least, appear how most with-flash pictures look).

  Actual results:  The picture with flash is almost completely black,
  with only a few dim details in the brightest parts of the image.
