Recently, the Ministry of Industry and Information Technology and the National Internet Information Office issued the Notice on Further Standardizing the Preset Behavior of Mobile Intelligent Terminal Application Software, which requires manufacturers to ensure that the preset application software in mobile intelligent terminals, except for basic function software, can be unloaded, and provide safe and convenient unloading methods for users to choose. The basic function software is limited to "basic components of the operating system: system settings, file management", "applications to ensure the normal operation of intelligent terminal hardware: multimedia recording", etc. At most one of the preset application software with the same basic function can be set as non uninstallable. Anyone who has ever used a smart phone has a feeling that many smart phones have too much software pre installed, and most of them cannot be uninstalled, which not only takes up a lot of memory, but also may reduce the speed of mobile phones. It has been reported in the media that there are more than 40 software pre installed on smart phones of well-known brands, and most of them cannot be uninstalled. The Ministry of Industry and Information Technology of the People's Republic of China and the National Cyber Information Office have issued the Notice, which clarifies that pre installed software other than basic functions can be uninstalled, which conforms to the voice of consumers and is conducive to better safeguarding consumers' right of choice. In the era of smart phones, software is an essential part of mobile phones. However, if there are too many pre installed software and it cannot be uninstalled, it is a disregard and infringement of consumer rights. From the legal perspective, the pre installed non uninstallable software infringes consumers' right to choose and know. The software that cannot be uninstalled will cause memory shrinkage, operation deceleration, body heating and other problems. Some software also forcibly push advertisements to obtain personal information, and even some shanzhai mobile phones are pre installed with rogue software that absorbs phone charges, consumes traffic, implants viruses, and sends fraudulent SMS messages, which is far beyond the normal business scope. The main purpose of many people to buy smart phones is to use software to enjoy the convenience of "Internet plus" beyond the phone and SMS functions. However, everyone has different hobbies. Consumers who do not need a certain function or software have the right to uninstall the software and choose the software they prefer and use more easily. However, due to memory limitations, downloading software with duplicate functions is obviously not the best choice. If consumers want to use better software, they have to bear the risk of memory consumption, poor operation, repeated loading of software, and even bear the higher risk of damaging mobile phone performance after the phone is flushed, which affects after-sales service. In short, unless basic functions are affected, pre installed non uninstallable software is a disguised form of "forced purchase and forced sale" and bundled sales. In addition, a large number of pre installed non uninstallable software is also suspected of cheating consumers. Many mobile phone manufacturers only emphasize powerful functions such as running memory and body memory when they promote marketing, and do not mention the non uninstallable pre installed software that occupies memory. When consumers purchase mobile phones, they focus on the pixels, running memory and body memory. Few people use the number of pre installed software as a reference for purchasing mobile phones. The right to design and construct a mobile phone lies with the manufacturer. However, how to use it after purchase and what software to use are consumers' freedom. My mobile phone is my own choice. The manufacturer has no reason to pre install non uninstallable software to interfere with consumers. Before, no matter how consumers responded, some manufacturers ignored the rights and calls of consumers, which led to too many non uninstallable software becoming a cancer that affected people's normal use of smartphones.
