Apple's mobile phone screen is scratch-proof and does not need film. Gorilla glass is an environmentally friendly aluminum-silicon toughened glass produced by Corning. This kind of glass has bulletproof function and is often used in helicopters. In general, unintentional damage will not cause scratches.

Abrasion resistance test

Scratch prevention has always been the most willing project for users. Some users intentionally scratch the screen with a knife or key to test the scratch resistance of the glass, and often no scratches are displayed after wiping the screen.

Reduce the brightness of the screen.

Film pasting will reduce the brightness of the screen. Even the AR film with high transmittance (also called high transmittance antireflection film) is only about 95%. Other types of mobile phone films will have a greater impact on screen brightness.

Reduce touch sensitivity

Sticking film will reduce touch sensitivity. After pasting the film, the screen that used to slide as fast as flying may become "stuck" and "unable to slide", reducing the touch experience of iPhone.

Unable to get warranty

Mobile phones with damaged film cannot be guaranteed. Users use mobile phone film that has not been certified by Apple MFi, and Apple does not guarantee the film because of corrosion damage. Apple's technical support representative once said in an interview that the unofficial behavior of pasting film is particularly popular in China.

The psychology of China users

The unofficial behavior of pasting film is particularly popular in China, which may be due to the fact that China users often don't simply regard the iPhone as a digital product considering the income level and the price of the iPhone, so it is difficult to accept its daily wear and tear as a digital product.
