Unity开发安卓平台指南针传感器无输出问题求助

大家好，我最近碰到一个Unity安卓指南针的棘手问题，实在搞不定了，想请教下各位大佬：

• 用Unity Remote通过USB连接PC运行时，指南针功能完全正常，能正常显示并跟随方向旋转；
• 但打包成APK安装到设备后，虽然会弹出位置权限请求，我点击授权后，指南针却完全没反应；
• 更奇怪的是，我在Start函数里明明设置了Input.compass.enabled = true，但在Update里检测到它会自动变成false，日志一直显示“Compass.enable stopped”；
• 我已经尝试提取并修改Unity生成的Manifest文件，添加了定位相关权限，但问题还是没解决。

我的指南针脚本代码 #

using UnityEngine;
using UnityEngine.Android;
using UnityEngine.UI;

public class Compass_Behaviour : MonoBehaviour
{   
    
    [SerializeField] Transform Compass;
    [SerializeField] Text Text01;
    [SerializeField] Text Text02;
    [SerializeField] Text Text03;
    [SerializeField] Text Text04;
    [SerializeField] Text Text05;    

    [SerializeField] float currentHeading;
    [SerializeField] float storedHeading = 0f;

    void Start()
    {
        Text01.text = "Check Location Approval";
        Text02.text = "Check Location.Status";
        Text03.text = "Check if Compass Stopped";
        Text04.text = "Check currentHeading";
        Text05.text = "Check StoredHeading";

        Permission.RequestUserPermission(Permission.FineLocation);
        Invoke("_LocationAskPermission", 1f);

        Input.location.Start();
        Input.compass.enabled = true;
    }
    void _LocationAskPermission()
    {
        if (Permission.HasUserAuthorizedPermission(Permission.FineLocation))Text01.text = "FineLocation Approved";
        else
            Text01.text = "FineLocation Denied";
    }
    void Update()
    {
        if(Input.location.status == LocationServiceStatus.Stopped || !Input.location.isEnabledByUser)
        {
            Text02.text = "location.status stopped";
            Input.location.Start();
        }
        if(!Input.compass.enabled)
        {
            Text03.text = "Compass.enable stopped";
            Input.compass.enabled = true;
        }
        currentHeading = Input.compass.trueHeading;
        Text04.text = "currentHeading: " + currentHeading.ToString();
         
        if (currentHeading != storedHeading)
        {
            if (currentHeading > storedHeading+5 || currentHeading < storedHeading-5)
            {
                Compass.rotation = Quaternion.Euler(0f, -currentHeading, 0f);
                storedHeading = currentHeading;
            }
            Text05.text = "storedHeading: " + storedHeading.ToString();
        }
    }
}

修改后的Manifest文件 #

我提取了Unity生成的临时Manifest并改成了永久版本，已经添加了定位相关权限：

</manifest>

我目前猜测问题可能出在权限申请时机或者Manifest配置上，但试了很多次都没进展，想问问大家有没有遇到过类似情况？或者有没有我没注意到的细节？比如：

• 是不是权限申请的顺序有问题？我在Start里先请求权限再开启定位和指南针，会不会权限还没授权就执行了开启操作？
• 除了ACCESS_FINE_LOCATION，安卓12以上的定位权限有没有特殊要求？
• Unity打包时会不会有隐藏设置覆盖Manifest配置？
• 会不会是设备硬件问题？但Unity Remote运行正常，应该不是吧？

期待各位大佬的指点，谢谢大家！
