  • the back shells of modern mobile phones are generally made of glass, metal and other more beautiful materials, but they cannot be used without wearing a cover. This is the unhealthy wind brought by Apple, adding some beautiful but meaningless structures, beautiful glass and metal back shells that can never be in contact with the air, and then wearing a heavy TPU cover, what is the difference with the direct use of plastic back shells? the difference? Excess glass and metal increase the weight of the mobile phone, and the TPU mobile phone case makes the mobile phone thicker and wider, which seriously reduces the feel of the mobile phone.
  • the user needs the freedom to choose the shell material. If the manufacturer can't provide it, at least the beautiful glass and metal back shell can really play a role and improve the user's feel. However, if it is used out of the mobile phone case, the toughened film with insufficient size cannot fully protect the front screen of the mobile phone, and the risk of broken screen becomes extremely high. When one of the four corners of the mobile phone display is hit, it will cause the broken screen.
  • the mobile phone protective film can reduce the risk of broken screen to a certain extent. However, because of the manufacturing accuracy and avoiding the roll-up of the protective film, the common protective film is usually smaller than the mobile phone screen and plays a more anti-scratch effect. . It is conceivable to use a portable device corner protection sticker similar to the US invention patent US 9,553,629 to circumvent the manufacturing accuracy problem:
