HDR extension doesn't work on Samsung Galaxy A52s 5G

When the HDR extension on the CameraX library is used (while using the back camera), while the preview is running logcat displays these lines continuously:

This goes on and on. When capturing a photo, the capture callback is never called. In logcat I can see the following errors:

Surface no longer in use[total_surfaces=6, used_surfaces=4](androidx.camera.core.impl.SessionProcessorSurface@1258a6c}

--

CameraDevice.onError(): 0 failed with ERROR_CAMERA_DEVICE while in OPENED state. Will attempt recovering from error.

--
Attempt to reopen camera[0] after error[ERROR_CAMERA_DEVICE]

--

Session 0: Exception while stopping repeating: android.hardware.camera2.CameraAccessException: CAMERA_ERROR (3): The camera device has encountered a serious error at android.hardware.camera2.impl.CameraDeviceImpl.checkIfCameraClosedOrInError(CameraDeviceImpl.java:2513)

See the attached logcat file log1.txt.

When using the front camera, the preview issues the same logs while the preview is running. Capturing a photo sometimes work (looks like it works when there is not a lot of difference in light intensity). When it does not work, the following error is logged:

Tag name 'dynamicShotCaptureDuration' does not exist.

See the attached logcat file log2.txt.

I followed the API documentation. The sample library (https://github.com/android/camera-samples) has the same behaviour. I also tried a third party CameraX app from the Play Store, taking a photo in HDR causes the same issue. Using code or an app that implements Camera2 directly does not cause any problems with HDR enabled.

Occurs with CameraX version: 1.3.4 and 1.4.0-rc01

I tried both PreviewView.ImplementationMode.PERFORMANCE and PreviewView.ImplementationMode.COMPATIBLE

Extensions Bokeh and Face Retouch do work.

Device: Samsung Galaxy A52s 5G

Model: SM-A528B/DS

Android version: 14 (build number UP1A.231005.007.A528BXXS9GXG5)

Hi,

Thanks for reporting the issue. I have created  https://issuetracker.google.com/issues/364152642 to track this issue and also looped you there. I will update the investigation results on the buganizer issue after doing some tests on our lab devices.

Thanks a lot for the investigation and quick fix!
