I'm sure those of you who have purchased or know about Apple phones are aware that there is a Face ID model in the Apple used phone market that is not working.This is where you might ask, "If Face ID is broken, why not just take it to a repair shop? In fact, once the Face ID of an iPhone is damaged, even if the user takes it to an official for repair, the official can only replace the entire device and cannot repair it individually, so the cost of repairing it can be imagined (some Huajiangbei masters can repair it).But according to reports from foreign media, this situation will change, as they learned through an internal Apple memo obtained from a reliable source that Apple Store shops and Apple authorized service providers will soon be able to repair the Face ID of the iPhone XS and newer models without having to replace the entire iPhone.However, you should note here that all iPhone XS and above models are supported, except the iPhone X, which uses Face ID for the first time and is not supported for repairs.However, the almighty Huaqiang North two years ago can repair Face ID alone, there are many netizens flirting: is this the Apple after-sales staff in Huaqiang North secretly learn the technology? Of course it is not possible to overstate the ability of Huaqiang North, Huaqiang North in repairing Face ID is also a certain probability problem, not all are able to repair good.How to fix Face ID by Huaqiang North master?Students familiar with hardware programming should understand that in fact the iPhone 13 series parts information is written to the hardware level (the chip has a communication relationship with the hardware), the security level is very good and difficult to solve through software. But if the original code is re-written to the new device, will it pass the system's authentication? The method is theoretically possible, the biggest difficulty in practice is how to write the previous chip code to the new hardware.For repairers or domestic Huaqiang North, copying hardware coding problems requires nothing more than the support of the appropriate equipment, which is currently available in Huaqiang North.Why does Apple offer a separate repair service for Face ID?Back to the question of why Apple is offering a Face ID individual repair service? Apple has officially stated that the Face ID individual repair service was introduced to reduce the number of complete replacements as part of Apple's commitment to reduce the carbon footprint of its products, and at the end of the day it's all about the environment.Regarding Face ID, Face ID is one of the more fragile parts of the iPhone, sometimes it can be damaged by a slight drop or accidental exposure to moisture. And once Face ID is damaged for iPhone users, it means you need to enter a passcode every time you unlock the phone. Users who are used to biometric unlocking such as Face ID and fingerprints will find it hard to revert back to a digital passcode. Apple provides Face ID independent repair service, and will definitely provide relevant documents and training (it is reported that Apple Store and authorized service providers can use the Apple Service Toolkit diagnostic tool to determine whether the Face ID module can be repaired or the whole machine needs to be replaced), At that time, the threshold for Face ID maintenance will be further lowered, and Huaqiangbei will have more room to play. For users, on the one hand, users can reduce maintenance costs, and on the other hand, Huaqiangbei’s refurbished machines will be more difficult to identify (air tightness). Inspection is still the best way to check that the original is not disassembled).Finally, for those who like more cell phone repair knowledge, welcome to follow us at oriwhiz.com for occasional updates on the latest information.Oriwhiz Parts is a manufacturer that specializes in the production and sale of cell phone repair screens, and also provides cell phone repair batteries and other replacement parts.
