Overview

Quirk which denotes JPEGs produced directly from the HAL may sometimes be corrupted.

QuirkSummary Bug Id: 159831206, 242509463 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
