For our thin and flexible screen protectors (Curved Crystal), try attaching tape to the corner of the screen protector and pulling it off the phone screen.
If the screen protector is a little bit thicker (Tempered Glass or Full Cover Glass), it can be removed by using a stiff card like an ID or credit card. Lift the screen protector with the card from any corner of the screen protector. Once the corner has been lifted off the device, hold the corner and remove slowly.
If you have a Galacase screen protector, it will not shatter into pieces. The tempered glass will hold all the pieces in place even if it is to crack. The Galacase will not damage or leave residue on your phone screen. Since all of our screen protectors are designed with a special silicone adhesive, it will not leave any residue on your screen if you choose to take it off.
