My android app build has more bugs on it than the editor/deveploment version

Hi

My problem is that, when I run my app on build version it has many bugs on it like bad quality, lagging and stuff like that. Everything was fine in editor.

Here's my code for the most of the bugs:

  void Update()
     {
 
 
         if (Input.touchCount == 1)
         {
 
             acumTime += Input.GetTouch(0).deltaTime;
 
             if (acumTime >= holdTime)
             {
                 transform.Translate(0, 4 * Time.deltaTime * 4, 0);
             }
 
             if (Input.GetTouch(0).phase == TouchPhase.Ended)
         {
                 acumTime = 0;
             }
         }
          
        
      
         else {
 
             transform.Translate(0, -5 * Time.deltaTime, 0);
 
         }
     }

On the editor, ball falls if user doesn't touch or hold the screen, and goes up when user touches the screen but in build version user hold makes the ball not move and move sometimes which is pretty weird. It also moves pretty weirdly up when user touches the screen.

PS. The text is also pretty low quality on build version. Why's that?
