how can i get exact my mobile device physical rotation on UI text.

     private bool gyroEnabled; 
     private UnityEngine.Gyroscope gyro;
     private GameObject GyroControl;
     private Quaternion rot;
     public Text text;
 
     Transform t;

         GyroControl = new GameObject("Gyro Control");
         GyroControl.transform.position = new Vector3(transform.position.x, 1, transform.position.z);
         transform.SetParent(GyroControl.transform); //parents the object to an empty control object
         gyroEnabled = EnableGyro();
 
         t = transform;
     }
     private bool EnableGyro()
     {
         if (SystemInfo.supportsGyroscope)
         {
             gyro = Input.gyro;
             gyro.enabled = true;
 
             GyroControl.transform.rotation = Quaternion.Euler(90f, -90f, 0f); //These offset values are essential for the gyroscope to orientate itself correctly
             rot = new Quaternion(0, 0, 1, 0);
 
             return true;
         }
         return false;
     }
     private void Update()
     {
         if (gyroEnabled == true && Xmode == true)
         {
             transform.localRotation = gyro.attitude * rot;
             t.eulerAngles = new Vector3(t.eulerAngles.x, 0, 0);            
             
             if (t.eulerAngles.x >= 180)
             {

         {
             transform.localRotation = gyro.attitude * rot;
             t.eulerAngles = new Vector3(0, 0, t.eulerAngles.z);
 
             if (t.eulerAngles.z >= 180)
             {
                 Zangle = 270 - t.eulerAngles.z;
             }
             else
             {
                 Zangle = 90 - t.eulerAngles.z;
             }
 
             DisplayZangles();
         }
         
         text.transform.rotation = Quaternion.Euler(0, 0, -t.eulerAngles.z);
     }
 
     public void DisplayXangles()
     {
         if (Switch == false)
         {
             text.text = Mathf.Abs(Xangle).ToString("0") + "°";
         }
 
         else if (Switch == true)
         {
             if (90 + Xangle <= 90) 
                 text.text = Mathf.Abs(90 + Xangle).ToString("0") + "°";
             else
                 text.text = Mathf.Abs(Xangle - 90).ToString("0") + "°";
         }
     }
 
     public void DisplayZangles()
     {
         if (Switch == false)
         {
             text.text = Mathf.Abs(Zangle).ToString("0") + "°";
         }
 
         else if (Switch == true)
         {

                 text.text = Mathf.Abs(90 + Zangle).ToString("0") + "°";

     public void SetXmodeToTrue()
     {
         Xmode = true;
         Zmode = false;
     }
     public void SetZmodeToTrue()
     {
         Zmode = true;
         Xmode = false;
     }
 
     public void SwitchWhenPressed()
     {
         if (Switch == false)
             Switch = true;
         else
             Switch = false;
     }

So this is how I created a bubble level (or an inclinometer to be more precise). The last 2 functions: SetXModeToTrue(), SetZModeToTrue() are called on button presses, which switches from measuring the angle of your phone on the x to the angle on your phone on the z. SwitchWhenPressed() is another function called on button press, which basically offsets your rotation. E.g., if perfectly flat was 90 degrees, you could press a button called Switch and it would say 0 degrees instead. Hope this helps anyone who needs it!
