Overview

Quirk which denotes single capture with JPEG format may have an output buffer smaller than the expected size.

QuirkSummary Bug Id: 315071023 Description: Addresses a potential issue where JPEG photo captures may result in smaller-than-expected output resolutions. In certain cases, even when configuring the maximum supported JPEG output size using , the captured ImageProxy may contain a photo buffer with a smaller resolution. This can lead to unexpected cropping or transformation issues during post-capture processing. Device(s): Redmi note 8 pro - front camera
