Issue in proximity sensor in iPhone 13 mini

I am facing a issue in my iphone 13 mini as when i am on call and phone is near my ear screen turn off but when i took phone far from my ear light does not on and always i have to push lock button twice which sometimes lead to cut the call as the proximity sensor not working properly. However when i use phone without screen protector it works absolutely perfect but i am facing issue when using it with screen protector. As i discussed to apple store they told me that screen protector is not up to the quality so i have purchased screen protector from apple store also but still same problem is happening and i have change many screen protection but with all i am facing this issue. So please provide solution.
