/**
* Quirk which denotes JPEGs produced directly from the HAL may sometimes be corrupted.
*
* <p>QuirkSummary
* Bug Id: <a href="https://issuetracker.google.com/159831206">159831206</a>,
* <a href="https://issuetracker.google.com/242509463">242509463</a>
* Description: Corrupt images generally manifest as completely monochrome JPEGs, sometimes
* solid green. On the affected devices, this is easier to reproduce
* immediately after rebooting the device. If possible, it is preferred
* that CameraX produce JPEGs from some other image format rather than
* receiving JPEGs directly from the HAL. This issue happens on Samsung Galaxy S7.
* The other issue is that the Exif metadata of the captured images might be
* incorrect to cause IOException when using ExifInterface to save the updated
* attributes. Capturing the images in YUV format and then compress it to JPEG
* output images can produce correct Exif metadata to workaround this issue.
* Device(s): Samsung Galaxy S7 (SM-G930T and SM-G930V variants), alps k61v1_basic_ref
