Because of the high cost and long turnaround time of official Apple stores, you can also go to independent repair and iPhone parts replacement stores. Most independent repair shops operate faster because they offer a same-day replacement solution for standard parts and come with companion iPhone repair parts such as charging port, camera, battery, screen, home button and motherboard. Because they don't use certified Apple parts, they charge less than what you can get from the Apple Store.Of course, there are plenty of options for fixing your iPhone. Restoration experts can fix things that have not been discovered before. But the fact is that some parts of the iPhone can be changed to disable certain features. Most elements in the iPhone are enabled at the factory level. These features only work in the BIOS of the Apple device and are implemented by built-in metrics designed by the original developers. As a result, users can experience some problems even if they replace the parts of a genuine iPhone after the repair.The common problem with an iPhone after a repair part replacementUnfortunately, even Apple's support center can't help restore the device's functionality. Here's a summary of some common problems that can occur after an iPhone has been repaired or any factory-set iPhone parts have been replaced.1. The iPhone's Home button is replaceable, but you'll have to live with a completely nonfunctional Touch IDThe home button on all iPhone devices is the trickiest part. If you break the home button, rip the cable, or in any way disable it, keep in mind that it cannot be restored to its original state. You can, of course, replace a broken button with a new one, but you have to sacrifice the ability to use Touch ID. This feature is factory-made and will disable Touch ID if the home button cable gets damaged. You can navigate with an auxiliary touch, but the home button is disabled for fingerprint recognition.The Home button component changes on all models above the iPhone 6 are cosmetic changes only. Even with replacement parts, TouchID or Fingerprint biometrics won't work2. FaceID of iPhone X and above will not be available after replacing the "EAR Speaker" unitHere's another iPhone repair fact, you need to know that if you change the speaker, the iPhone's FaceID won't work. This mainly applies to iPhone X and above. On the iPhone X, Apple removed the home button from the display and introduced FaceID. The FaceID hardware setup is the "TrueDepth Camera System", which is associated with adjacent sensors and ambient light sensors. So when the iPhone's "ear speaker" is replaced, FaceID becomes non-functional.3. Replacement of any iPhone motherboard will not recognize the device with the original IMEI number on Apple's serversFinding My iPhone is an iPhone feature that prevents people from using your Apple device. So when a user shuts down their iPhone, the Apple ID is stored on Apple's servers and is secure, and the ID is connected to the device. This link is through the phone's motherboard, so after replacing your iPhone's motherboard, the device cannot be recognized by the original IMEI number on Apple's servers.4. Screen changes on iPhone 7 and above can trigger sensor failureIf your iPhone's screen is broken, replacing it sounds like a good option. But even an actual screen change in Apple stores could cause some sensor issues with the latest iPhones. Some of the problems you can see are problems with the ambient light sensor or the screen brightness adjustment. Also, in some cases of screen replacements, the "True Tone" feature in the "Display and Brightness" option may not appear.If your iPhone device breaks, you can choose other ways to fix it or replace the broken part. While at some point you may have to compromise on the phone's features and overall functionality, it's wise to accept that.Oriwhiz (Shenzhen DongYe Tengfei Electronic Co., Ltd) is a professional iPhone repair parts, iPad, iMac, Mac Book, Xiaomi, Huawei, Samsung, Sony, LG, Asus repair parts and repair tools supplier which has served thousands of repair shops with wholesale parts and hundreds of thousands of individual customers with the parts needed to fix their own iPhone, iPad, MacBook, and other digital devices.
