If your screen is non-responsive, you should check if it is either broken or dirty. If it’s broken, it should be replaced. We highly recommend to do it through a certified supplier or retailer. On the other hand, if the screen is dirty, you should swipe it with a microfiber tissue in order to remove any grease or water that could interfere with the touchscreen correct operation.
