    The shadow is displayed correctly when checked on a PC, but the position of the shadow is shifted when checked on an Android device.

    This happens when the Rendering Path of Camera is set to Deferred.

    I changed many settings, such as Bias, Shadow Projection, Light Render Mode, and shader, but there was no change.

    Light was confirmed with Directional Light and Spot Light, but both had Peter Panning.

    What is the problem?

    Thanks in advance.

    When I created a test project for the report, it was displayed successfully.

    We will investigate for a while.

    The exact cause is unknown, but a workaround has been identified.

    I set the Near value of the camera's viewport Rect to 0.01, but I confirmed that changing it to 0.3 can avoid it.

    No bug report has been filed because it is unknown how to reproduce the issue exactly.

    sorry.

    no problem!
    with the near plane value too small, depth loses precision very quickly
