Hi @alexanderbelousov25 , Looking at your logs, I understand you're encountering a graphics interface initialization error with the HMS Unity Plugin on your MatePad SE 11. Let me help explain what's happening and provide some solutions.

The error occurs when the HMS Plugin attempts to initialize the hardware graphics interface on HarmonyOS 2.0. This is particularly common on tablet devices due to their different screen configurations and how HarmonyOS handles hardware abstraction layers.

There are a few potential solutions you can try:

Solution 1 - Update HMS Core Settings
First, ensure your HMS Core and related services are up to date through AppGallery on your MatePad. This is crucial as outdated services can cause initialization failures.

Solution 2 - Implement HMS Tablet Configuration
In your HMS initialization script, add specific tablet device handling:

using HuaweiMobileServices.Utils;
using UnityEngine;

public class HMSInitializer : MonoBehaviour
{
    void Start()
    {
        Screen.fullScreen = true;
        
        try
        {
            var config = new HMSConfig();
            config.SetTabletConfig(true);
            HuaweiMobileServicesUtil.SetApplication(config);
            Debug.Log("HMS Core initialized successfully");
        }
        catch (System.Exception e)
        {
            Debug.LogError($"HMS Init Error: {e.Message}");
        }
    }
}

Solution 3 - Update AndroidManifest Configuration
Add the following to your AndroidManifest.xml to properly handle tablet mode:

<meta-data
    android:name="com.huawei.hms.client.screenmode"
    android:value="tablet" />

After implementing these changes:

1. Clean your Unity project (delete Library and Temp folders)
2. Rebuild your project
3. Deploy to your device

If you're still experiencing issues after trying these solutions, please share any new error messages you encounter. I'll be happy to help further troubleshoot the problem.

Let me know how these solutions work for you!

Best regards
