androidx.camera:camera-view:1.0.0-alpha12

CAMERA APPLICATION NAME AND VERSION: (Settings > Apps > (app name) > version)
1.0

ANDROID OS BUILD NUMBER: (Settings > About > Build number)
R16NW.G930VVRU8CRJ3

DEVICE NAME: (Nexus 5X, Samsung S6, etc)
Samsung Galaxy S7 (SM-G930V)

DESCRIPTION:
For some camera sessions CameraX will produce completely green images. In those sessions I see 20-30% of photos taken being completely green. In other sessions I see no issues.

LIST ANY EXPERIMENTAL FEATURES: (As an example - @ExperimentalCamera2Interop)
Unaware of any.

STEPS TO REPRODUCE:
1. Take photos in rapid succession
2. Save photos to media store
3. View photos

OBSERVED RESULTS:
Some photos appear completely green, others appear normal.

EXPECTED RESULTS:
All photos should appear normal

REPRODUCIBILITY: (5 of 5, 1 of 100, etc)
10 of 100

ADDITIONAL INFORMATION:
This issue is critical to my team, as users can't immediately review all photos and when taking several photos they may easily miss the green photos. This leads to critical loss of data.
I've attached a logcat grab for a session with 7 photos, 2 of which turned out green.
Please ignore the ADB logcat error "camera is closed" at the end of the capture, as I closed the camera too quick while it was still processing. I believe this is my own fault.

CODE FRAGMENTS (this will help us troubleshoot your issues):
// capture code - outputPath is null in all tests, which leads to saving to MediaStore:
// Create output options object which contains file + metadata
val contentValues = ContentValues().apply {
put(MediaStore.MediaColumns.DISPLAY_NAME, "Untitled")
put(MediaStore.MediaColumns.MIME_TYPE, "image/jpg")
}

// Create the output file option to store the captured image in MediaStore
val outputOptions = when (outputPath) {
null -> ImageCapture.OutputFileOptions
.Builder(
context.contentResolver,
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
contentValues
)
.build()
else -> ImageCapture.OutputFileOptions
.Builder(File(outputPath))
.build()
}
