/**
* <p>QuirkSummary
* Bug Id: 196755459, 205340278
* Description: Quirk that requires Preview surface is in front of the MediaCodec surface
* when creating a CameraCaptureSession.
* On some Samsung devices, create CameraCaptureSession will fail silently if
* the input surface list does not have a Preview surface in front of a
* MediaCodec surface.
* On Pixel 1, when the MediaCodec surface size is 3840x2160(UHD) and the
* input list for creating CameraCaptureSession does not have Preview surface in
* front of the MediaCodec surface and ImageCapture surface, Preview will have
* interlaced color lines after start recording. MediaCodec surface resolutions
* for 1920x1080(FHD), 1280x720(HD) and 720x480(SD) do not have this issue. Not
* clearly know if there is another resolution will encounter this issue, but
* this quirk should be safe to apply regardless the video surface resolution
* since the workaround just sorts the surface list while creating
* CameraCaptureSession.
* Device(s): Some Samsung devices and Pixel 1
* @see SurfaceSorter
