Hi,

I am since long observing a bug affecting nearly exclusively the Samsung Galaxy A24, when transforming the imageProxy returned from onCaptureSuccess, into a Bitmap. I initially thought it was due to my own code, since I previously coded the transformation myself, however recently I have implemented CameraX's own .toBitmap() function, and the issue still persists. Below you can find the stack trace (I redacted some information with Xs for privacy reasons): 

Fatal Exception: java.lang.UnsupportedOperationException
Decode jpeg byte array failed

Is this a bug, or am I implementing something incorrectly here?

Kind regards, 
Michael

This looks like the same issue as https://issuetracker.google.com/309005680

Charcoal,  do you think our workaround can also fix the in-memory capture case ?

Yes, our workaround can also fix the issue for in-memory capture.

Hi, 

Samsung has a fix for the issue that is included in the latest FOTA(different regions might receive the FOTA build at different times). And as Charcoal said,  CameraX also has a workaround for the issue that MIGHT fix the issue, the workaround will be included in the March release.
