If there is a mobile phone that can drive the whole industry on its own, the iPhone is definitely on the top. From material design to manufacturing, from distribution and retail to after-sales maintenance, every time Apple releases a new mobile phone, the related industries can almost “get a share”. < / P > < p > for example, the most common mobile phone repair shop in our daily life, no matter whether the shop is large or small, whether the qualification is complete, whether the screen is changed or the battery is changed, almost every shop has iPhone related business. On the one hand, this hot business depends on the market share of iPhone, and on the other hand, it has something to do with Apple’s own after-sales policy. Since Apple implemented the “replacement repair” policy, there are only two ways for the iPhone to break down: either go to the apple store to “repair” for half the price of a mobile phone, or find a “professional repair” nearby. < / P > < p > but for this year’s iPhone 12, things have become a bit tricky: according to the dismantling website ifixit, after replacing the camera, the iPhone 12 series needs special software certification to make the camera work properly. < / P > < p > after dismantling the latest iPhone 12 series, ifixit swapped two iPhone 12 cameras. Although the mobile phone can light up normally after being installed, it can’t switch to the ultra wide angle camera. After switching mode and lens for many times, the mobile phone appears the phenomenon of “black lens”. In the subsequent investigation, ifixit believed that this was due to the hardware restrictions on the replacement of “foreign lens” on the software level of iPhone 12. Ifixit also said that “according to Apple’s internal repair and training guidelines, when repairing the camera and screen, you need to run Apple’s special cloud software to completely repair the camera and screen.”. < / P > < p > in fact, before the iPhone 12, Apple had a “criminal record” of setting restrictions in mobile software. Anyone who knows a little about iPhone maintenance should know an operation called “code writing”: every part in the phone has a corresponding “serial number”. When the phone is in use, it will detect the serial number of these hardware. If the hardware serial number is different from the serial number recorded on the motherboard, the phone will “function abnormally, or the screen will crash white”. For example, in the past, the original color, face ID and fingerprint of the mobile phone may not work normally after the mobile phone is repaired in unauthorized outlets, so it is necessary to “write the code” separately, and write the replaced hardware sequence code into the original hardware code. < / P > < p > in addition to the camera module, ifixit also tried to swap the screens of two iPhones 12. Although the two screens are 100% genuine, the iPhone will still prompt “the screen may not be genuine” after replacement, which proves the existence of “software certification” on the other hand. < / P > < p > in my opinion, Apple’s reasons for doing so can be roughly divided into two aspects. First of all, software authentication can ensure the security of mobile phones. Many people may not know that the fingerprint or face data of iPhone will not be uploaded to the cloud, and all fingerprint or face recognition is a completely offline local operation. This ensures personal data security, but it brings another hidden danger: just like the operation in spy, if the illegal elements disassemble and replace the chips with their fingerprints, then can you brush your mobile phone and WeChat Alipay? < / P > < p > in order to curb this situation, it is necessary to record the hardware code of key components of mobile phone. For example, the T2 security chip in the Mac computer records the characteristic information of various components in the computer, and “identifies” all hardware before starting up, so as to eliminate the phenomenon of hardware “changing locks”. The same is true for the iPhone. The key hardware codes in the phone will be stored in the phone, so as to avoid the phenomenon of cheating. < / P > < p > but here comes the problem. If Apple really wants to ensure information security, it can only record the hardware code related to security. The battery, screen, rear camera and other hardware have nothing to do with information security. Why do they need to check? Is the reason for recording the hardware codes of these peripheral hardware to “wipe out” the third-party repair shops? < / P > < p > as I said just now, the iPhone used to record the hardware code in the name of “security”, and it also used the hardware code to judge whether the phone had replaced the hardware. In addition to the screens and faces mentioned just now, third-party batteries are also the hardest hit areas for hardware codes. Friends who have replaced a third-party battery should know that generally speaking, a third-party battery cannot check the battery health in the device; iPhone 7 and iPhone 8 also have a certain probability of vibration failure after replacing the linear vibration motor. < / P > < p > when the news just came to light, some people thought that this was Apple’s new way to curb unauthorized maintenance in the name of “hardware security”; however, the functions of original color display and battery health did not affect the normal use of mobile phones, so most users would still choose more affordable unauthorized maintenance. < / P > < p > but in the case of iPhone 12, even if the spare parts are from genuine iPhones, simple hardware exchange will lead to camera failure and screen error, which is a bit unreasonable. In the past, in order to distinguish it from unauthorized maintenance, Apple has always boasted that it uses genuine Apple parts. However, the example of iPhone 12 screen swapping with camera has proved that even if the unauthorized maintenance uses genuine parts, the repaired mobile phone still can’t work normally. < / P > < p > in essence, this can be regarded as Apple’s “stumbling block” for users and unauthorized maintenance in mobile phones in order to safeguard its own and partner’s interests. In the long run, this will bring a huge blow to the mobile phone maintenance industry – who can guarantee that Apple will not restrict other components? It happens that apple is going to promote MagSafe ecology. If it wants to change the back cover in the future, it has to look for the apple store and buy a mobile phone case from the original factory. Otherwise, it will pop up? < / P > < p > although I bought Apple care + for the first time for every apple product, in my opinion, Apple’s “unreasonable” way of doing things is really incomprehensible. With this pace of development, apple can add hardware locks to every part of the mobile phone, and even “specify” the service life of the hardware like the printer cartridge. For example, the screen will be forced to go black after how many hours of lighting, and the capacity of the battery will automatically “return to zero” after how much power is released. I believe this will definitely stimulate the sales of AppleCare +. < / P > < p > but the problem is that when the threshold of “mobile phone maintenance” is raised to a certain extent, consumers will naturally choose brands with lower “cost of using the phone”. Mobile phone damage is inevitable, since there is an official authorization to repair, then there are also not authorized to “eat by craft” mechanic. Through the way of “replacement repair”, Apple has increased the “zero to whole ratio” of iPhone repair. Although it can increase the revenue of after-sales service, it will also push consumers to other brands. In the future, whether the “peripheral industries” of iPhone can blossom like now depends on the performance of apple in the future. Global Tech
