While using GrapheneOS new Camera app which uses cameraX we discovered an issue with the Samsung a3 2017. If we take a photo using the flash in low light then we end up with a black image. The discussion started here https://github.com/GrapheneOS/Camera/issues/239 It appears that the flash and actual image capture are not in sync. I did test directly with a cameraX sample app using this:

        imageCapture = ImageCapture.Builder()
                .setCaptureMode(ImageCapture.CAPTURE_MODE_MAXIMIZE_QUALITY)
                .setFlashMode(ImageCapture.FLASH_MODE_ON)
                // We request aspect ratio but no resolution to match preview config, but letting
                // CameraX optimize for whatever specific resolution best fits our use cases
                .setTargetAspectRatio(screenAspectRatio)
                // Set initial target rotation, we will have to call this again if rotation changes
                // during the lifecycle of this use case
                .setTargetRotation(rotation)
                .build()

And i can reproduce the issue. The phone model is SM-a320FL but i would guess it also happens with sm-a320F

As the devs of the grapheneos app explained our device might need to be added to the list here https://android.googlesource.com/platform/frameworks/support/+/refs/heads/androidx-main/camera/camera-camera2/src/main/java/androidx/camera/camera2/internal/compat/quirk/FlashTooSlowQuirk.java

Hope there is enough info.

Thanks
