iPhone Face ID Stopped Working After a Fall: How to Fix It?

Face ID is one of the most advanced and convenient features on iPhones, from the iPhone X to the latest iPhone 17 Pro Max. This facial recognition system offers security and ease of use, but it can stop working correctly after the phone is dropped. If your iPhone suffered an impact and Face ID stopped responding, it is essential to understand the possible causes and available solutions to restore this functionality.

At iServices, specialists in smartphone repairs in Portugal, we understand the importance of Face ID in our customers' daily lives. Therefore, we present a comprehensive guide explaining why Face ID might stop working after an accident and how to proceed to resolve the issue safely and quickly.

Causes for Face ID Failure After a Drop

TrueDepth Sensor Damage

Face ID works thanks to the TrueDepth sensor array, which includes an infrared camera, dot projector, and flood illuminator. A drop can misalign or damage these highly sensitive components, preventing correct facial recognition.

Cracked or Damaged Screen

Impacts that cause cracks or damage to the screen can interfere with Face ID functionality, as the sensors are integrated at the top of the display. Even small fissures can distort the laser projections, affecting the system's precision.

Software Glitches Following an Impact

Sometimes, the physical shock can trigger temporary glitches in the iOS software that manages Face ID. These issues can often be resolved through configuration adjustments or system updates.

Logic Board Damage

In more severe drops, the iPhone's logic board may suffer damage that affects communication between the sensors and the processor, resulting in Face ID failure. This is a complex situation that requires specialized technical intervention.

Why does Face ID stop working after a drop?

Following a fall, essential components like the TrueDepth sensor array or the screen can suffer physical damage or internal misalignment, preventing correct facial recognition. In some cases, the impact causes a hardware disconnect that can only be solved by a specialized technician.

Can I try to repair Face ID at home?

We strongly recommend against DIY repairs. Face ID involves highly sensitive technology that is cryptographically linked to the iPhone's processor. Inadequate intervention can permanently disable Face ID. Always seek help from certified professionals like the iServices team.

How long does a Face ID repair take at iServices?

The repair time depends on the specific fault. Screen replacements can often be done within the same day (express service), while complex logic board repairs may take longer. We prioritize speed without compromising quality.

Is Face ID covered by a warranty after the repair?

Yes! All repairs performed by iServices come with a 3-year warranty (with the exception of batteries, which have 1 year). We use high-quality parts and expert techniques to ensure the durability and reliability of our service.
