Great! Thanks a lot, I'll look for the live updates soon!

Thanks for the response.

Just to confirm all of the steps:

1. I've run CameraXBasic sample, and that's how the app behaves on SNE-LX1 (see video step_1.mov).

2. I've changed the scaleType property for PreviewView to fitCenter, and make aspectRatio(width:height:) method to always return AspectRatio.RATIO_4_3. The result is in step_2.mov.

3. I've added the following part of code after photo is taken:

   val exif = ExifInterface(photoFile.absolutePath).apply {
       setAttribute(
           ExifInterface.TAG_ORIENTATION,
           ExifInterface.ORIENTATION_ROTATE_90.toString()
       )
   }
   exif.saveAttributes()
   

   and it works fine. You can see the result in step_3.mov.

Answering your questions:

1. The output image seems to be fine, not cropped.
2. Exactly. I don't have access to Honor 9X device, but this is the output from Sentry - Brand: HONOR, Model: STK-LX1 (HUAWEISTK-LX1) (the (HUAWEISTK-LX1) part is added by Sentry, rather than it's clear output from Build.MODEL).
3. The device I've borrowed has API 29. The users that have reported the issue had also devices with API 28.
4. The device I've borrowed - yes. I assume that the other devices had also GMS apps installed.

Thanks for providing the detailed information.

About the 3rd question, could you help to check the camera device hardware level but not the Android API level? The code in Java may look like the following:

CameraManager cameraManager =
        (CameraManager) context.getSystemService(Context.CAMERA_SERVICE);
CameraCharacteristics characteristics = cameraManager.getCameraCharacteristics(cameraId);
int hardwareLevel = characteristics.get(CameraCharacteristics.INFO_SUPPORTED_HARDWARE_LEVEL);

I want to confirm the camera device HW level is because that one CTS test should have checked the captured image's EXIF orientation value. But it only tested non-Legacy devices. Non-Legacy devices shouldn't encounter this issue. Therefore, I want to confirm the Huawei Mate 20 Lite and the Honor 9X's HW level to confirm the issue root cause is the same as what I supposed to. Thanks.

Oh, sorry, I misunderstood.

So for the Huawei Mate 20 Lite the camera device HW level is 0 (INFO_SUPPORTED_HARDWARE_LEVEL_LIMITED). Unfortunately I'm unable to check the value for Honor 9X easily, but if it's necessary just let me know (I think it will take a few weeks, cause I need to log this info in the production level app).

Thanks.

Could you also help to provide the Build.DEVICE info of these two devices? Thanks.

For Huawei Mate 20 Lite it's HWSNE. Unfortunately, I'm unable to provide you info for Honor 9X.

Hi,

We're clarifying this issue with the camera framework team and need your further help to provide some more information. So that we can know all the details and might be able to improve the CTS tests to cover this in the future.

1. What is the problematic image size when capturing the image in target aspect ratio 4:3 setting?
2. Could you help to provide the JPEG supported sizes list of the Huawei Mate 20 Lite device? I'm not sure whether it is the same as you have been provided in b/161156062#comment4.
3. Could you provide a bugreport that is dumped right after operating to capture the problematic 4:3 image?

Thanks in advance.

Hi,

1. I didn't specify target resolution, but I've check with max available resolution (3840x5120) and custom one (1200x1600), both times the issue has occurred.
2. Yes, it is the same list I've provided.
3. In attachments.

Please let me know when you will have any plans to cover this issue.

Thanks. This issue will be targeted to be fixed in Dec release.

Thank you. I'm looking forward to it.

Hi,

Could you help to install and check whether the issue can be resolved by the attached apk?

What I modified:

1. Force CameraFragment#aspectRatio() to return AspectRatio.RATIO_4_3.
2. Do not use JPEG_ORIENTATION capture request parameter and rotate the output image according the target rotation setting. This is only applied to the Huawei Mate 20 Lite and Honor 9X devices by Build.BRAND and Build.MODEL.

Please take pictures in 0, 90 and 180 and also help to dump and extract logs with tag "b171492111-debug". So that I can analyze whether the solution work as expectation.

Thanks.

Friendly ping :)

Hi,

It won't stop the fix. The purpose is just to verify my solution can really resolve the problem since I do not have device to verify it. I'll still prepare the fix in the next release.

The solution has been merged in https://android-review.googlesource.com/c/platform/frameworks/support/+/1492739. Please wait for the next monthly release in Dec that will include it.

Hi,

Great news, it works on real users' devices. Thank you for resolving this.
