Bug description:
Dell System Inspiron 14 7000 Series 7437
CPU: Intel(R) Core(TM) i7-4500U CPU @ 1.80GHz (4x)
GPU: 00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09)

HA4-E3-C1 Primax (0bda:5601 , 50-77501WNC8)
HA7-E3-C2 Liteon (0bda:5750, _13P2SF109)
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.
When testing by manually take still images in different resolution, camera will hangs when switch to another resolution.
Steps:
1. install manifest X08 and boot into OS
2. Run camera test "multiple-resolution-images" which takes multiple pictures based on the resolution supported by the camera and validates their sizze and that they are of a valid format.
Expected results: Test got passed with multiple images successfully
taked in each resolution.
Actual results: Can't take still image in each resolution.
