Hi,

This seems to be similar to this issue, which was recently fixed. The fix should be available in the next release.

I also got the same issue with a HXY A9 Pro. The log is attached.

The issue happens as soon ProcessCameraProvider#hasCamera(CameraSelector.DEFAULT_BACK_CAMERA) is called.

I believe this issue was fixed with commit: https://github.com/androidx/androidx/commit/ce0f240daff678d89a2ed386fcd6c8d12e498609

Am I right?

If yes, if the device is using an inverted value for the zoom level, wouldn't that cause the device to behave to zoom in when the user tried to zoom out and vice versa?

I mean, if the values for min and max zoom are inverted, doesn't it mean that the zoom level is also inverted, and in this case 0.1 means 0.9?

I don't have any problematic device to test it, but I'm just worried if that would work as expected, as the fix only inverted the values for min and max zoom levels.

Hi,

Correct, that's the commit where the fix was made.

| if the device is using an inverted value for the zoom level

I don't think the zoom level is being reported in a reversed manner. The min digital zoom value is 1 by default, and the max should be greater than or equal to 1. I think the fix that was implemented sets the max digital zoom to 1 if CameraCharacteristics.SCALER_AVAILABLE_MAX_DIGITAL_ZOOM is erroneously reported on the device, this happens if it's null or less than 1 (the min zoom).

@scottnien is that the case?

Okay, got it! I think that makes sense, in this case the zoom level will be between 1.0 and 1.0 (min and max).

Yes, the issue is caused by incorrrect SCALER_AVAILABLE_MAX_DIGITAL_ZOOM being reported on these devices. SCALER_AVAILABLE_MAX_DIGITAL_ZOOM is expected to >= 1, but it seems to be < 1 on these devices.

The issue is fixed at this CL and will be released soon this month.

FWIW this bug also happens in Redmi Note 8, model GINKGO, codename ginkgo Android API 10 when using cameraX 1.0.0-beta12 version. Will update to the latest and see if it keeps happening:

Hi grzegorz Thanks for the reporting this. I believe the issue has been fixed in latest version (both 1.0.0 RC or 1.1.0 alpha) Please let us know if you still encounter the issue.
