CameraX Orientation Issue on Fast Rotation

[Ali safwat - علي صفوت‎]

I’ve encountered an issue while using CameraX related to device orientation handling. When the device is rotated quickly (for example, from portrait to reverse portrait or vice versa), the system successfully detects the orientation change, but the CameraX preview UI does not update accordingly.

I’m using LocalConfiguration to determine the current orientation, and it reflects the correct orientation value after rotation. However, the camera preview UI remains unchanged, which indicates that the CameraX preview or its layout does not refresh properly during rapid rotations.

In my tests:

• On a Huawei Nova 5T, the orientation is detected and the camera UI updates correctly.

• On other devices, the issue occurs — the orientation is detected but the camera UI fails to update.

It seems this issue appears mainly during fast rotations, not when rotating the device slowly. Could you please investigate this behavior or provide guidance on ensuring consistent UI updates across devices?

Hi there, 

Are you using PreviewView or CameraXViewFinder or your own implementation to display the camera preview ?

I am using Preview view

Hi , 

This is possible caused by a device issue that display rotation doesn't give correct rotation after DisplayManager.DisplayListener onDisplayChanged is invoked. 

Can you give us the device names that have these issues?  and can you also update the device if possible to see if the issue is resolved ?

This issue appears on multiple devices, including the Samsung S24 Ultra, Xiaomi Poco F3, and many others. One device on which the problem did not occur is the Huawei Nova 5T

Thanks for confirming it.  I believe it is the same issue. I filed a bug here and we will investigate if we can find solutions to fix it.
