OEM Nuglas Glass Screen Protector 3D for Samsung Galaxy A40 Black

The full face tempered glass is a full-coverage tempered glass protector, specially made to protect your phone's screen from scratches and other damage. If the phone is dropped, it does not guarantee that the screen will not break along with it, but it does provide additional protection. It does not affect screen operation. It has adhesive across its entire surface, unlike edge glue glass protectors, which have adhesive only around their perimeter. This helps it fit better and ensures trouble-free touchscreen operation. It also prevents dust from getting underneath, which can happen with edge glue when the adhesive around the perimeter wears out. It is compatible with the Galaxy A40.
