RenderTexture usage for camera screenshot

Unity Engine
1

I’m having some problems using RenderTexture in the editor and on the device (ios). I am trying to get a screenshot from only a camera. In the editor, the image gets messed up and on the device i get a black texture and this error:

OpenGLES error 0x0502 in /Users/…/GlesHelper.mm:262

Here is the code:

	yield return new WaitForEndOfFrame(); // this also captures gui, remove if you don't wanna capture gui
		
                RenderTexture rt = new RenderTexture(Screen.width, Screen.height , 24 , RenderTextureFormat.ARGB32);
         	rt.useMipMap = false;
		rt.antiAliasing =1;
		RenderTexture.active = rt;
		Camera.main.targetTexture = rt;
		
		
		Texture2D shot = new Texture2D(Screen.width,Screen.height,TextureFormat.ARGB32,false);
			
	
		Camera.main.Render();
			
		shot.ReadPixels(new Rect(0,0,Screen.width,Screen.height),0,0,false);
                shot.Apply();
			
		Camera.main.targetTexture = null;
                RenderTexture.active = null;
		Destroy(rt);

               GameObject.Find("PlaneTest").renderer.material.mainTexture = shot;

The code is called on a press event.
What am i doing wrong?

i’ve changed a bit of the code, but the problem was from the camera. The clear flag was set to Don’t clear instead of Depth only
