clicks pass through UI elements on android

I have 2d objects that respond to mouse clicks. There is a UI panel For the whole screen and when I click on this panel, clicks are triggered on objects under the UI panel. How to fix it? I do it on the phone. Unity Version 2019 This code works on a PC, but not on a phone public void OnMouseDown() { if (EventSystem.current.IsPointerOverGameObject() || EventSystem.current.currentSelectedGameObject != null) { } else { WoodFarmPanel.SetActive(true); }

     }
