(android game) When i don't touch the screen, my fps are lower than when i touch

Hi Guys! I've had a problem for a long time with smooth camera on mobile phone (platformer game), but I reported that my game works well when my fps don't drop below 60. I notice that my fps are fine when i touch a screen, but when i don't do it, fps drop to approximately 58, 59 and after that my camera don't follow my player smoothly. For testing i create new scene with only FPSCounter script and the effects are the same. Could someone help me with it? I think that it is engine settings reasons, but i can't handle with it.

//---------------------------------------------
// VARIABLES
//---------------------------------------------

private float deltaTime = 0.0f;

//---------------------------------------------
// METHODS FROM SUPERCLASS
//---------------------------------------------

void Update()
{
deltaTime += (Time.deltaTime - deltaTime) * 0.1f;
}

void OnGUI()
{
GUIStyle style = new GUIStyle();
float x = Screen.width - 110;
float fps = 1.0f / deltaTime;

Rect rect = new Rect(x, 90, 100, 50);

style.fontSize = 18;
style.normal.textColor = getColor(fps);

string text = string.Format("{0:0,0.0000 FPS}",fps);
GUI.Label(rect, text, style);
}

//---------------------------------------------
// CLASS LOGIC
//---------------------------------------------

private Color getColor(float fps)
{
if (fps >= 60)
{
return Color.yellow;
}
return Color.red;
}

 

I don't know why your FPS is doing that. I do have a different suggestion; there's no need to re-create the GUIStyle each OnGUI call; you can just create it once in Start() and store it in a variable.

 

You're right, but it doesn't solve a problem. The mobile requires touching screen constantly to provide optimal number of FPS. How can I do this ?
