Why is my android game upsidedown?

hi, i am trying to make a android game but when i test it on my phone its upside down. the only thing i made is a box that can jump and it will move when you tilt the screen.

  #pragma strict
 
 var walkspeed: float = 5.0;
 var jumpheight: float = 250.0;
 var grounded = false;
 
 function Start() {
 
 
 
 }
 
 function Update() {
 
     rigidbody.freezeRotation = true;
 
     if (Input.GetKey("w")) transform.Translate(Vector3(0, 0, 1) * Time.deltaTime * walkspeed);
     if (Input.GetKey("s")) transform.Translate(Vector3(0, 0, - 1) * Time.deltaTime * walkspeed);
     if (Input.GetKey("a")) transform.Translate(Vector3(-1, 0, 0) * Time.deltaTime * walkspeed);
     if (Input.GetKey("d")) transform.Translate(Vector3(1, 0, 0) * Time.deltaTime * walkspeed);
     
     for (var touch : Touch in Input.touches) {
     if (touch.phase != TouchPhase.Ended && touch.phase != TouchPhase.Canceled) {
         Jump();
         }
     }
 }
 function OnCollisionEnter(hit: Collision) {
     grounded = true;
 }
 
 function Jump() {
     if (grounded == true) {
         rigidbody.AddForce(Vector3.up * jumpheight);
         grounded = false;
     }
 }

and the Tilt code: #pragma strict

 function Start () {
 
 }
 
 function Update () {
        var dir : Vector3 = Vector3.zero;
  
     dir.x = -Input.acceleration.x*.5;
  
     transform.position.x += dir.x;
 }
