When your iPhone begins to show signs of malfunctioning, it could be due to a problem with the logic board, a crucial component housing essential parts of the device. But can you replace the logic board on your iPhone with Face ID? Yes, but you need to install the follwing hardware that matches:
- Logic Board
- Front Facing Camera Assembly (Paired to that logic board)
- Proximity Sensor / Earphone Assembly (Paired to that logic board)
You need to find a factory matching set of those 3 or your Face ID will no longer function.
Understanding iPhone’s Logic Board
The logic board, also known as the motherboard, is the heart of your iPhone. It houses key components such as the CPU, memory, and connectors for the battery and camera. Essentially, it’s the control center coordinating all functionalities of your iPhone.
Importance of Face ID
Face ID is an advanced facial recognition feature that provides a secure and convenient way to unlock your iPhone, authenticate payments, and log in to apps. However, it’s directly connected to the logic board, adding complexity to any replacement procedure.
The Challenge in Replacing the Logic Board
Replacing a logic board on an iPhone with Face ID is no easy task. Due to the tight integration of components, replacing the logic board also involves replacing the Face ID system. It’s because the unique pairings between these components are secure, which makes transferring the Face ID data to a new logic board impossible.
Can You Replace the Logic Board Yourself?
While some tech-savvy users might be tempted to undertake this task, it’s not recommended for the average person due to its complexity and the risk of causing further damage to your iPhone. Unless you have professional-level skills and specialized equipment, it’s best to leave this to the experts.
A qualified technician who has the knowledge and access to the correct parts (that match) will be able to confirm that the system operates properly and install a replacement logic board that is compatible with Face ID.
The Risks Involved in Logic Board Replacement
Attempting a DIY logic board replacement carries risks, including the potential loss of Face ID functionality and voiding your iPhone’s warranty. Additionally, you risk damaging other components or even rendering your iPhone unusable.
Professional Logic Board Replacement
Getting your logic board replaced professionally, either by Apple or a trusted third-party service, is the safest and most reliable solution. They have the necessary tools and expertise to perform this delicate procedure without causing further damage.

If I change the screen on my iPhone, will Face ID still work?
If an experienced technician replaces the screen on an iPhone with Face ID the right way, the Face ID feature should still work afterwards. The TrueDepth camera system and the flood illuminator, which are often built into the device’s front display assembly, are two of the components that make up the Face ID system.
It’s essential to make sure that these parts are moved over from the old screen to the new one during a screen replacement. Face ID functionality may be impacted if the replacement is carried out incorrectly and these components are damaged or misaligned.
It is advised to get the screen replaced by an expert service provider or a recognized repair facility that uses premium replacement components and has skilled technician that is an iPhone repair expert in order to avoid potential problems.
Additional Advice
Apple linked several parts to the logic board in order to boost security and thwart any Face ID hacking efforts. That means that for Face ID to continue to function, these parts must be moved together as a set. This indicates that you will require a matched set of:
- Logic Board
- Front-facing camera assembly
- Proximity Sensor / Earphone Assembly
If you want FaceID to work after a repair, make sure those 3 are all part of a matching set. That means that if you have an iPhone that has some other problem with it, you can harvest those components from it as a set and they should still be functional. You could buy a different phone or frame that is compatible with your present one and move those 3 components over. In the opposite scenario, you could theoretically buy a phone that has those three components compatible to transfer into your existing phone if any one of those are not functioning in your current phone. The Face ID should work as long as the 3 components listed move as a set.
To prevent any “unknown components” errors, you will also want to move the mic flex over.
Conclusion
In conclusion, while it’s technically possible to replace the logic board on your iPhone with Face ID, it’s not a task that should be undertaken lightly. Given the complexities and risks involved, seeking professional help is the best course of action.
