The emergence of smart phones has sparked a new industry: Mobile phone film. The reporter found that there are really many types of mobile phone films on the market, not only plastic films, tempered glass films, but also smart films, anti-blue light films... The most amazing thing is the privacy film. It is said that after the privacy film is attached, only the owner of the mobile phone can see the screen clearly, while others see it as a "black screen". Can privacy really be protected with a privacy film attached? The reporter conducted an actual test.

On the road, under the overpass, and even in the subway, you can see the figure of the film boy everywhere. There are five, ten and even hundreds of films.
