iPhone 18 Pro Face ID Not Working: Reboot Bug and the Definitive Fix
Independent guide — no official affiliation with the platforms mentioned.
छोटा जवाब
On the iPhone 18 Pro, Face ID failures are usually caused by a known software bug: when authentication fails while opening a protected app, the device freezes or restarts. Force-restart the phone, then install iOS 26.0.2 or later under Settings > General > Software Update; Apple fixed this bug in the update announced on September 24, 2026. If it persists, reset Face ID and re-enroll your face.

STEP 01
Confirm the known bug is the cause
Does it happen specifically when opening the Passwords app, private Safari tabs or another Face ID-protected area? If the screen freezes or the phone restarts during authentication, it matches the software bug confirmed on iPhone 18 Pro and Pro Max in September 2026. It is not a hardware failure, and an update resolves it.
STEP 02
Force-restart the iPhone
Press and release Volume Up, then Volume Down, then hold the Side button until the Apple logo appears (about 10 seconds). This clears a stuck Face ID prompt and most temporary freezes; no data is lost.
STEP 03
Install the iOS update
Go to Settings > General > Software Update. Apple announced on September 24, 2026 that an update fixes the restart-after-Face-ID bug and shipped it as iOS 26.0.2. If your phone shows this version or later, install it; after updating, the issue disappears for the vast majority of users.
STEP 04
Reset Face ID and re-enroll
Go to Settings > Face ID & Passcode > Reset Face ID; this deletes only your face data, not your files. Then tap Set Up Face ID and re-enroll in good lighting, holding the phone 25-30 cm away. If you see the 'Face ID can work at this distance' hint, bring the phone slightly closer.
STEP 05
Temporary workaround: use your passcode for protected areas
While waiting for the update, turn Face ID off temporarily for the Passwords app and Safari private-tab lock under Settings > Face ID & Passcode. Use your device passcode for those areas instead; this sidesteps the bug entirely until the update arrives.
STEP 06
Reset All Settings (your data is kept)
Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. Photos and apps are not deleted; only Wi-Fi passwords and system settings return to defaults. Set up Face ID again afterwards and monitor for a day.
STEP 07
If it persists, request remote diagnostics from Apple Support
If authentication still fails on the latest iOS, start diagnostics via support.apple.com. If the TrueDepth camera has a physical fault, service replaces the Face ID module under warranty; within the first 14 days you can also use your return or exchange rights.
सुझाव
- This bug is not hardware-related; install the update and re-enroll Face ID before booking a service appointment.
- Holding the phone too close during Face ID enrollment lowers scan quality; 25-30 cm is the ideal distance.
02 — अक्सर पूछे जाने वाले प्रश्न
अक्सर पूछे जाने वाले प्रश्न
When did Apple fix the Face ID issue?
Apple officially confirmed a software fix on September 24, 2026, and the update shipped shortly after as iOS 26.0.2. Install the latest version under Settings > General > Software Update.
Does resetting Face ID delete my photos or apps?
No. 'Reset Face ID' only deletes your face data. Even 'Reset All Settings' keeps your files; only settings return to defaults. Both are safe to perform without any data loss.
Which models are affected?
Reports focus on iPhone 18 Pro and iPhone 18 Pro Max; the standard iPhone 18 is rarely affected. Because the cause is software, the update fixes every affected model the same way.
Face ID is completely dead - what should I try before service?
In order: force restart, latest iOS, Face ID reset, then Reset All Settings. If it still fails, check Settings > Face ID & Passcode for a 'Face ID has been repaired on this device' style notice; if present, service is required.
