Hello.

I’m looking for a solution to fix my device’s screen refresh rate, but I can’t find it.

First, I wrote the code like this,

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class RefreshRateManager : MonoBehaviour
{  
    public Text txt, txt1;

     void Awake()
    {
        QualitySettings.vSyncCount = 0;
        Application.targetFrameRate = 60;
        //Screen.SetResolution(1280, 720, true, 60);

        txt.text = "Refresh Rate : " + Screen.currentResolution.refreshRate.ToString();
        txt1.text = "FPS : " + Application.targetFrameRate.ToString();
    }
}

but, it doesn’t work.

Next, I found this thread( Set screen refresh rate on Android 11 ), so I followed it.
However, the result is same.

And now, I can’t find any other solution.

Please describe your problem.

Oh, I’m sorry.
Perhaps my question didn’t explain my problem so much.

I want to switch my android device’s refresh rate to 60Hz when I run my game, when the refresh rate of my device is 120Hz.

Can you describe why? Perhaps I’m not following. Might this help? https://support.unity.com/hc/en-us/articles/360000283043-Target-frame-rate-or-V-Blank-not-set-properly

Because my Galaxy S20+ overheats when its refresh rate is not 60Hz.

And I already set VSync Count to Don’t Sync, but it didn’t change my device’s refresh rate.
