Most screens of your smartphone are made up of glass. The reason for this is that glass provides a much better clarity then fiber or plastic. And as we all see, the screens are very much bigger in size than the earlier keypad handsets. An accidental drop from even a not so high place can crack the screen of your handset, replacement of which can prove expensive and moreover time-consuming. To avoid this, you should keep your device in a protective cover or a padded pouch which can easily absorb the impact of the drop.
