/**
* <p>QuirkSummary
* Bug Id: 288828159, 299069235
* Description: Quirk required to check whether the captured JPEG image contains redundant
* 0's padding data. For example, Samsung A5 (2017) series devices have the
* problem and result in the output JPEG image to be extremely large (about 32 MB).
* Device(s): Samsung Galaxy A5 (2017), A52, A70, A71, A72, M51, S7, S22, S22+ series devices
* and Vivo S16, X60, X60 Pro devices. This issue might also happen on some other
* Samsung devices. Therefore, a generic rule is added to force check the invalid
* JPEG data if the captured image size is larger than 10 MB.
