iPhone Face ID Repair in Sydney - Restored at Chip Level
Yes, Face ID can usually be restored after a screen replacement. At Cheap Mobile Repair we recover the original encrypted data from your iPhone TrueDepth sensor array and micro-solder the original chip onto a new flex cable, so your iPhone recognises it as its own. Face ID then works as it did before. Diagnosis is free.
Why Face ID stops working after a repair
Face ID relies on the TrueDepth sensor array: the dot projector, the flood illuminator and the infrared camera. These sit on paper-thin flex cables that run directly against the back of the display, so they can be strained or torn while a screen is being removed.
The flex also carries a small encrypted chip that is cryptographically paired to your iPhone logic board. That pairing is why a replacement module cannot simply be fitted: your iPhone will not accept a chip it does not recognise. Restoring Face ID therefore means recovering the original data and returning the original chip to service.
What we do about it
We examine the sensor array under a high-magnification microscope, identify which component has been affected, and recover the original encrypted data. The original chip is then desoldered, re-balled and micro-soldered onto a new flex cable using specialist programming equipment. Your iPhone accepts it as its own, and Face ID works again.
It is board-level work, and it is the kind of repair Cheap Mobile Repair has built its reputation on. Other repair businesses bring us their most difficult jobs for exactly this reason.
Other faults we repair after a screen or back glass replacement
- True Tone missing after a screen replacement – the display data must be copied from your original screen to the new one.
- Front camera or proximity sensor not working – the front sensor flex sits alongside the display and can be affected during removal.
- Fingerprint reader not working on Pixel or Samsung – the under-display sensor is calibrated to the exact screen it sits behind and must be recalibrated.
- Apple Pay or buttons not working after a back glass replacement – the NFC antenna and button flex sit directly beneath the back glass.
- iPhone will not turn on after a repair – usually the battery flex, a board connector or the backlight circuit, all repairable at board level.
All of these are repairable at Cheap Mobile Repair, and diagnosis is free.
Face ID repair questions
Can Face ID be fixed after a screen replacement?
Yes, in most cases Face ID can be restored. At Cheap Mobile Repair we recover the original encrypted data from the TrueDepth sensor array and micro-solder the original chip onto a new flex cable, so your iPhone recognises it again. Face ID then works as it did before. Diagnosis is free.
Why did Face ID stop working after my screen was replaced?
The TrueDepth sensor array sits directly against the display, and its flex cables can be strained or torn while a screen is being removed. That flex carries an encrypted chip paired to your iPhone logic board, so fitting a new part on its own does not restore the feature. The original chip has to be recovered and transferred.
Why can a new Face ID part not simply be fitted?
Every TrueDepth sensor array is cryptographically paired to the iPhone it was built with, so no pre-programmed replacement module exists. Restoring Face ID means recovering the original encrypted data and micro-soldering the original chip onto a new flex, which is board-level work carried out under a microscope.
My iPhone says Face ID is not available. Can you help?
Yes. Cheap Mobile Repair repairs the fault behind that message at chip level, whether it sits in the dot projector, the flood illuminator or the infrared camera. Bring your iPhone to our Burwood or Newtown store, or we can collect it free of charge. Diagnosis is free and we tell you honestly what can be restored.
Which iPhone models can you repair Face ID on?
We restore Face ID on every iPhone model that uses it, from iPhone X through to the latest releases, including Pro and Pro Max models. The work is the same in principle across the range: recover the original encrypted data and transfer the original chip to a new flex.
How long does a Face ID repair take?
Most Face ID repairs are completed within one to two days, because the work involves microscope diagnosis and micro-soldering rather than a simple part swap. We confirm the timeframe with you upfront, and we can provide a free loan phone so you are not left without a device.
