All phones have the disadvantage of vulnerable corners. When hit on the corners the phone’s screen can crack because the glass is not flexible and cannot bend. PanzerGlass has been through several tests where it withstood drops up to 1.5 meters’ height on to a concrete floor. Having PanzerGlass on is still an advantage if the phone’s corners are hit. If you choose to fit a PanzerGlass Premium onto your mobile device, the corners are even better protected, as it will cover the entire front.
