When you buy a new phone or tablet, it is a good idea to buy a glass screen protector, if you want to avoid damage and scratches on the device. A screen protector from PanzerGlass is incredibly hard-wearing and is made of real glass rather than the cheaper options such as protective film.
It is easy to apply a screen protector from PanzerGlass and if you break it, it is easy to replace. When you drop or scratch the screen on a phone with a screen protector on your device, it is the Panzer glass and not the actual phone screen that gets damaged. It is also a good idea to invest in a cover if you want to better protect your smartphone or tablet.
