Prevention and countermeasures of five major mobile phone quality problems Prevention and countermeasures of five major mobile phone quality problems • At present, consumers\' complaints about mobile phones are concentrated on screen damage, flip cover failure, crash, automatic shutdown, high drop rate, motherboard failure, poor mobile phone signal, key failure, poor call quality, etc. According to statistics from the Quality Dispute Technical Appraisal Center of China Telecommunication Technology Laboratory, among these problems, screen damage accounts for 20.4%, liquid ingress disputes account for 8.7%, shell and flip cover failures account for 8.6%, crash accounts for 7%, automatic shutdown accounts for 6.6%, poor voice quality and loud noise account for 5.6%, key failure accounts for 5.5%, weak signal accounts for 5.3%, and short standby time accounts for 5%. It can be seen that screen damage, mobile phone water ingress, flip cover failure, crash and automatic shutdown have become the five major quality problems that mobile phone users are most worried about. Problem 1: Screen damage Screen damage is the most troubling problem for consumers. Because the display screen itself is relatively fragile, it cannot withstand the impact of external forces such as bumps, falls, and squeezing. The larger the mobile phone screen, the easier it is to be damaged. Flip phones have certain advantages over candy-bar phones in terms of screen protection. Some users like to put their phones in their trouser pockets, which can easily damage the screen. Poor display quality is another reason for screen damage. Design defects cause the display screen to age or burn out due to long-term display, or even explode. However, since there is no specific standard for screen protection, it is difficult to determine whether it is a product quality problem or improper use when facing a dispute over mobile phone quality. Even if it is not improper use by the user, the dealer will not think it is a product quality problem. If there are marks on the shell, it is considered to be damage caused by falling; if there are no marks on the shell, it is considered to be damage caused by squeezing. In order to ensure the legitimate interests of users, such standards should be issued as soon as possible. It is reported that the China Telecommunication Technology Laboratory of the Ministry of Information Industry has reported a new standard for mobile phone screens, which is expected to officially become an industry standard in the middle of next year. Reminder: Users should carefully choose a repair shop when repairing their mobile phones, and be careful about the selected repair shop...
