With the introduction of the iPhone X in 2017, Apple Inc. introduced the Face ID feature. This feature improved the security of the Apple iPhone by almost 20 times compared to Touch ID while also providing additional convenience for the user. Since then, Apple has released several models of iPhones and iPads that come with the Face ID feature. However, it can be troublesome when Face ID is not working, causing inconvenience.
There are some traditional methods for fixing Face ID issues that involve disassembling the phone, welding, and aligning the device, which is time-consuming and labor-intensive. To solve this problem, REWA Tech introduced the latest and innovative REFOX RP30 multi-functional programmer. The RP30 can not only solve iPhones with Face ID issues, but it can also restore battery health and the true tone function of iPhones. It is our belief that by mastering the use of this device and technique, one will be able to greatly increase the efficiency of iPhone repairs.
REWA Tech understands the complexity of the Face ID repair or solution for iPhones, which is why we have designed a very simple solution for you to use. The only thing you need to do is to follow a few simple steps in order to resolve the issue.
The first thing we need to confirm is whether the failure of Face ID was caused by the dot fusion projector or not. So we turn on the phone to check Face ID. The screen shows that there is a problem detected with the TrueDepth camera. Face ID has been disabled. Then we dial the number to see if the proximity sensor and flood illuminator work properly. While focusing, the camera shows move farther away when set to portrait mode. Therefore, we can make a preliminary judgment that the issue of Face ID failure is caused by the dot fusion projector.
After judgment, place the phone screen face down on top of the heating pad to heat it. We choose to use a screen opener to take the screen off and remove the battery and Face ID.
Next, put the battery and screen back into the phone and connect the phone to the computer. Then link the Face ID to the RP30 Projector for testing. The results show that the dot projector was fused. So we can use the latest solution to repair it.
Back up the data on the dot projector and connect the programmer to the high-voltage power cable.
Click activate and wait for the activation process to be completed. After the activation process, snap the dot projector cable onto the programmer and then write in the data that has been previously backed up. Then remove the dot project cable and snap the Face ID.
Be sure to pay attention to the folding process. If you have doubts about this, you can check our video or contact us for further discussion.
Connect the Face ID to the programmer again for the test. The test result is normal. Put Face ID back on the phone and install the battery and screen. Turn the phone on to test. Face ID can be set normally and unlocked successfully.
Above is the latest Face ID repair solution shared. Since this is a very simple and easy-to-follow solution that requires no soldering, level 2 technicians can now easily correct complex Face ID problems.
Fixing Face ID issues on an iPhone used to be a complicated process that required disassembling the phone and performing complex operations. However, with the introduction of the RP30 multi-functional programmer, level 2 technicians can now easily fix complex Face ID problems without soldering or complicated operations. This not only saves time but also reduces labor costs, making it an excellent choice for cell phone repair shops looking to improve their efficiency and customer satisfaction.
The no-soldering solution for fixing Face ID represents a significant advancement in the field of phone repairs. The step-by-step process for using the RP30 programmer is easy to follow, and the results are impressive.
One of the major appearance differences between iPhone 12 Pro and iPhone 13 Pro is that iPhone 13 Pro has a smaller notch. After the iPhone 13 Pro teardown, we find that the TrueDepth camera system of iPhone 13 Pro is less of the flood illuminator than iPhone 12 Pro. The missing flood illuminator is one of the reasons why the notch is smaller.
The front camera module of iPhone 13 Pro is also smaller than iPhone 12 Pro. The dot projector is moved to the middle with obvious outlook differences. We guess it may have something to do with the missing flood illuminator. The missing flood illuminator is probably integrated with the dot projector.
In this video of a repair case, REWA LAB will find out where the missing flood illuminator is and what influences the change of design by Apple will bring to Face ID repairs.
The Face ID of the iPhone 13 Pro is not available. Then we take apart the phone. Disconnect the battery and remove the display.
To avoid potential damage, apply high-temperature tape on the front camera module before repairing. Next, yank the motherboard, earpiece speaker and front camera module out.
In the first place, we connect the front camera module with the programmer. Then connect the phone to the computer. Click “Pearl Unbind”.
After unbinding, attach the front camera module to the holder. Carefully grind the metal plate with a grinding pen. Pry up the metal plate with a sculpture knife. Then cut the pin.
The next step is to remove the dot projector with hot air gun at 120 °C. It can be seen that the dot projector of iPhone 13 Pro is integrated with the flood illuminator. The CMOS of the infrared camera is put aside.
Then we remove the chip with hot air gun at 330 °C. Clean the bonding pads with soldering iron at 360°C. Keep cleaning the bonding pads with solder wick. Please do not damage the gold wire or smudge the CMOS during operations.Scrub the bonding pads with PCB cleaner.
Apply some paste flux to the bonding pads. Align the PCB board. Solder the board with hot air gun at 330°C
To facilitate subsequent IC soldering, we flatten the bonding pads. Then put the IC in position. Solder the chip with hot air gun at 330°C.
After that, we connect the flex cable with the programmer. Connect the phone with the computer. The new IC binds the phone successfully.
Next, we install the flex cable for testing. The settings of Face ID can be open and the flood illuminator works fine.
Then we need to assemble the front camera module. After alignment, apply some adhesive
Once the adhesive is set, install the front camera module. Connect the screen and battery. Turn on the phone. Face ID can be set up and works perfectly.
The flood illuminator of iPhone 13 Pro is integrated with the dot projector, which can make the notch smaller but brings new challenges for Face ID repairs. Compared to the old method of flex cable replacement and module transfer, the new way is more difficult and demanding for handwork. REWA LAB recommends non-professionals do not try this as it might damage the Face ID for good. We will keep you posted on the latest Face ID repair solutions for iPhone 13 series.
Today we will share a repair case on how to repair iPhone X Face ID not working.
The phone used to keep restarting. After testing, it was found that the earpiece flex cable was faulty. We replaced it with a new earpiece flex cable. The restarting problem was fixed but Face ID was not working and True Tone disappeared. This is because Face ID needs dot projector, infrared camera and floodlight illuminator to work together. The three parts are encrypted separately, so each part is indispensable. Both damage and replacement will result in the Face ID not working. The dot projector and infrared camera can be fixed if damaged. Because its data is bound to the motherboard, the floodlight illuminator on the earpiece flex cable can’t be repaired if damaged. Since the floodlight illuminator is in the earpiece flex cable, the data is hard to read.
If the Face ID is not working because the earpiece flex cable has been replaced or damaged, there is no way to repair it. But recently this type of problem has a solution and the original flex cable is no longer needed.
In the first place, we need to jailbreak the iPhone. Connect the phone with the computer. Open the software and click “Start”. The phone is in recovery mode automatically. Put the phone into DFU mode manually. The jailbreaking has succeeded.
Then connect the phone to J-BOX. Connect the J-BOX to the computer. Select “Face”. Begin reading data. We can see that the data of the distance sensor and ambient light sensor don’t match the data on the motherboard. It can be confirmed that the earpiece flex cable has been replaced, which resulted in the Face ID not working.
Open the JCID Repair Assistant. Click “Detect” and unlock automatically.
Then we use V1S to write the data. Connect V1S and phone to the computer. Get a new JC earpiece flex cable. Attach the earpiece flex cable to V1S.
Open the JCID Repair Assistant again. Click “Connect” and start testing.
Click “Activate FPC”. Bind the flex cable to the phone.
Next, we only need to install the new flex cable with written data.
Disassemble the phone and disconnect the flex cables. Remove the display assembly and detach the earpiece flex cable. Install the new earpiece flex cable. Connect the display assembly. Assemble the phone. Turn on the phone to test. True Tone has been restored. Face ID can be set up and is working normally.
As we all know, iPhone X and later models can easily come with Face ID failure after being dropped or water damaged. However, it should also be noted that improper operation during daily repair might also bring damage to Face ID relevant components and therefore result in Face ID not working failure. Today REWA LAB will show you how to repair iPhone 11 Pro Max Face ID issues.
When trying to set up Face ID on the iPhone, we get the message 'Face ID is Not Available, try setting up Face ID later'. Start the Camera app and select Portrait in the bottom bar, then switch to the front camera. When the camera detects a person's face, the name of the lighting effect ‘Natural Light’ stays the same and there is also no flashing red light from the Dot Projector.
Let's check the Face ID parts first. We found the earpiece speaker and sensor flex cable are normal. The dot projector flex cable, the infrared camera flex cable, and the front camera flex cable also haven’t been damaged. The next step we should check the motherboard. Run diode mode measurement of the earpiece speaker and sensor connector, and the dot projector connector. The measured value is normal. Continue measuring the infrared camera connector. Judging by the measured value, the Pin 8 relevant circuit has open-circuited. The normal value should be 260 or so. Outputted from PMU, the 1.8V voltage reaches Pin 8 of the infrared camera connector by way of the inductor circled in red on the bitmap. Next, we just need to check the relevant components of the rail. We found the inductor is damaged. Our initial judgment is that when replacing the screen, the improper operation of our client during flex cable disconnecting accidentally damaged the inductor.
Remove black adhesive around the inductor firstly. Apply some medium-temp solder paste to the bonding pad. Then, tin the bonding pad with solder paste with the help of the Soldering Iron at 365℃. Once done, clean with PCB Cleaner. Continue to apply some rosin to the bonding pad and get a zero-ohm resistor in the right position. Solder with Hot Air Gun, then Clean with PCB Cleaner afterward. Run diode mode measurement of Pin 8 on the infrared camera connector. The measured value is 257, which is normal.
Reassemble and Test
Get the logic board assembled and buckle the display assembly. The name of the lighting effect ‘Natural Light’ turns yellow when the camera detects a person's face. There is also a flashing red light from the Dot Projector. Next, continue to set up Face ID. Fault cleared.

Face ID is a facial recognition system that substitutes Apple's Touch ID fingerprint scanner on certain devices. It utilizes sensors displayed around the iPhone's user confronting camera to check your face and, if the output coordinates with the record information, perform activities like unlocking the phone or approving an Apple Pay exchange.
How Does Face ID Work?
The notch at the highest point of the iPhone screen on viable devices is the place where the sensors utilized by Face ID are found. These sensors include:
Dot Projector: This projects more than 30,000 imperceptible dots onto your face. The spots are utilized to plan the construction and profundity of your face. That forms a three-dimensional "special facial guide," as indicated by Apple.
Infrared Camera: This camera peruses the spots from the Projector and catches a picture.
Flood Illuminator: This extra infrared light guarantees that the framework works even in obscurity.
The facial guide caught by the infrared camera is coordinated against the information put away on your iPhone to open or approve the Apple Pay exchange. It's likewise used to make animated emojis planned to your face.
The framework is savvy and sufficiently touchy, as per Apple, that it can remember you regardless of whether you change your hairstyle, wear glasses, develop or shave facial hair, and age. All things considered, there have been a few cases in which Face ID has misidentified individuals, including twins and youngsters who look a ton like their folks.
What Is Face ID Used for on iPhone?
Face ID is utilized for a large number of exactly the same things as Touch ID. Generally significant among these are:
• Approving Apple Pay transaction.
• Unlocking the iPhone instead of entering a password.
• Providing your Apple ID passwords.
What Devices Support Face ID?
Face ID is upheld by the iPhone X and later models.
It's almost guaranteed that, actually like Touch ID started on the iPhone and has been added to different devices like the iPad, Face ID will ultimately show up on other Apple devices like the iPad.
Is My Face Scan Stored in the Cloud?
No, Face ID faces are not stored in the cloud. All face checks are kept straightforwardly on your iPhone. They are held in the "Safe Enclave," one of the iPhone's chips that is committed explicitly to getting delicate information. This is also where fingerprint data made by Touch ID is placed.
How Secure Is My Face Scan?
The way that the Secure Enclave works makes Face ID exceptionally secure. Your facial output itself isn't really stored on your iPhone. All things being equal, when the facial output is made, it's changed over to a number that addresses the scan. That is kept on your iPhone.
Regardless of whether a programmer had the option to get to the information in your iPhone's Secure Enclave (which is impossible), all they would get is a number, not a real scan of your face. That implies they would not have the option to utilize the information to present your data to another facial recognition system.
How to Set up and Use Face ID
Setting up Face ID is very basic—truth be told, you most likely did it while setting up your new iPhone. Simply position your face in the onscreen casing and roll your head around until the circle around the edge is filled in. Repeat however many times as the phone advises you and you're finished.
In the event that you skirted that progression during setup, you can generally return and add Face ID later. To do this, go to Settings > Face ID and Passcode and adhere to the onscreen directions.
You can also add different appearances to Face ID on your iPhone including somebody you trust just as option pictures of you (with and without a facial hair growth or glasses, for instance).
How to Disable Face ID
On the off chance that you need to rapidly disable Face ID, press the iPhone's side button and volume down buttons simultaneously. To empower Face ID once more, you'll need to reenter your password.
How Does Face ID Compare to Other Smartphone Facial Recognition Systems?
In spite of a solid portion of doubt when it was reported, Face ID has been a hit with users and critics. The general agreement is that it's exceptionally exact, extremely quick, and very simple. By and large, the progress away from Touch ID to Face ID has been quicker and smoother than the vast majority anticipated.
It's also demonstrated, indeed, how great Apple is at this kind of development. At the point when Face ID launched there was one major phone out with this sort of innovation: Samsung S8. Tragically, that system has been demonstrated to be extremely simple to trick, including by holding up a photo. Along these lines, the Samsung framework appears to not be secure. Samsung will not permit its facial outputs to endorse monetary exchanges (the manner in which Touch ID can on an iPhone).
Use Face ID When Wearing a Face Mask
The iOS 14.5 update permits users to open their iPhone X and later utilizing Face ID while they're wearing a face veil. To utilize this feature, you'll need an unlocked Apple Watch Series 3 or later and your iPhone nearby. Simply look at your iPhone, and afterward your Watch will give haptic input telling you the iPhone is unlocked.
How does Apple Face ID work with a scarf?
Face ID is intended to work with head covers and eyewear. It ought to be able to perceive your face regardless of whether you are wearing a cap, scarf, glasses, contact lens, and even many sorts of shades.
Does Apple Face ID work when eyes are shut?
No, it doesn't. Face ID is attention mindful and can perceive if your eyes are open and your attention is coordinated towards the device. This assists with keeping somebody from unlocking your device without your knowledge.
