  Both of the modules use realtek chipset.

  In the 1280x720 resolution only have half image displayed camera
  preview and still image; in 960x540 resolution camera preview
  displayed with full black but camera LED is enabled.

  Furthermore, camera test "multiple-resolution-images" also failed.

  taked in each resolution.
