A broken screen protector is a thin layer of material, often made of glass or plastic, that is designed to shield the screen of a device, such as a smartphone or tablet, from scratches and impacts. When it cracks or shatters, it can compromise its protective function, leaving the underlying screen vulnerable to damage. While a broken screen protector may not affect the device's performance, it can be visually unappealing and may hinder touch sensitivity. Users often choose to replace it to maintain the device's appearance and ensure continued protection for the screen beneath, which is typically more expensive to repair or replace.
