People are using smartphones more than ever. iPhone users needed a function that can give them relieve in terms of reducing eye strains. We use iPhone in night time or closed room or open space, white light does play important role to increase discomfort level with “True Tone” new function, Apple introduced in 2017. We’ve tested it, and it’s true: iOS 15.2 stops Face ID from malfunctioning after you replace the screen on an iPhone 13, outside their official repair channels. He then suggested that there are some workarounds like other parts to the new screen, but that most repair shops wouldn’t do that because it’s “too sophisticated.”
When we covered the original Phone Repair Guru video, he said that even when you replace your iPhone 13 screen for another original display, a message saying “Unable to verify this iPhone has a genuine Apple display” appeared. We can’t really say whether iOS 15.2 “fixes” this issue, or “corrects” it, or “undoes” it, because Apple won’t say whether its imperilment of the phone repair industry was a bug, a design decision, or an experiment. When it announced that Face ID would no longer fail after (non-Apple-sanctioned) screen replacements, it did so with a single non-attributed statement to The Verge about “a software update.” There’s no mention of Face ID function or repairs in the official iOS 15.2 release notes. The iPhone display is engineered together with iOS softwarefor optimal performance and quality.A nongenuine display might cause compatibility or performance issues. For example, an issue might arise after an iOS software update that contains display updates. You are now set up, and your V1 is up to date and now compatible with iPhone 11 models. You can now start transferring True Tone and other data onto models from iPhone 8 through to 11 Pro MaxI vacillated between the V1SE and the iCopy device, but ultimately settled on the iCopy. However, it turns out the iCopy software doesn't let you read the screen data from the phone itself, so I had to find another way to get that data without the original screen.
The JC V1 is a tool used in the mobile device repair industry to transfer screen serial data from the original screen to a new screen; this will keep many of the original features used on today’s iPhones. Many repair techs in the industry use this tool to restore data from previous repair works which have not included this feature and new repairs. In this how-to guide, we’ll cover how to use the JC V1 to fix True Tone on your device, and how to upgrade the board to allow the tool to support the new iPhone 11, 11 Pro and 11 Pro Max. How do I use the JC V1 to take data from one screen and transfer to a new screen? Then the warnings arrive, one after the other: “Important Camera Message,” “Important Battery Message,” “Important Display Message.” There’s an intriguing, if small, discrepancy between the warnings: it cannot “verify” the battery, rather than “determine” the screen or camera, and the concern is a genuine Apple “battery” rather than “part.” Our guess is that the battery warning is older and the copy hasn’t been updated. You can either dismiss the message with “OK” or “Go to Settings for more information.”From our research, the iPhone communicates with the screen through a microchip embedded on the screen.This screen microchip is an integrated circuit (an assembly of electronic components fabricated into a single unit) responsible for translating your analog touch (your finger pressing on your screen creating an analog signal) to a digital signal (for your iPhone to understand as your iPhone is a mini-computer and doesn’t understand analog signals) Please see video below of the JC V1 data transfer. After you have followed this guide, install the new screen to your device. For most customers, visiting a professional repair provider with certified technicians who use genuine Apple parts is the safest and most reliable way to get a repair. Theseproviders include Apple and Apple Authorized Service Providers, and Independent Repair Providers,who have access to genuine Apple parts.*Repairs performed by untrained individuals using nongenuine parts might affect the safety of the device or functionality of the display. Apple displays are designed to fit precisely within the device. Additionally, repairs that don't properly replace screws or cowlings might leave behind loose parts that could damage the battery, cause overheating, or result in injury. There seem to be two programmers that are popular with repair people; I have the Qian Li iCopy programmer myself, and the other one is the JC V1s device. They will both do the basic True Tone data copying, along with things like resetting battery statistics and a few other things. I haven't verified this, but it appears the V1s may have a little more capability for programming certain features related to Face ID and Touch ID, but details are somewhat sketchy, so you'd definitely have to do your homework on that.
