How to Fix iPhone 17 Camera Not Working After iOS 26.3 Update

iPhone 17 Camera Not Working After iOS 26.3 Update usually means the camera process crashed, app permissions changed, or one mode of the camera stack did not load correctly after the update.

Method 1: Force close Camera and restart the iPhone

The camera process may have frozen after the update and needs a clean restart.

Close the Camera app from the app switcher.
Restart the iPhone 17 normally.
Open Camera again and test photo and video capture.

Method 2: Check camera permissions and restrictions

If permissions changed during the update, the camera may open to a black screen or fail inside apps.

Open Settings > Privacy & Security > Camera.
Make sure the affected apps are allowed to use the camera.
Also check Settings > Screen Time > Content & Privacy Restrictions for camera restrictions.

Method 3: Switch between front and rear cameras

This helps determine whether the issue affects one lens, one mode, or the whole camera service.

Open Camera.
Try Photo, Video, Portrait, and the front camera.
See whether the issue happens only in one mode or lens.

Method 4: Update apps and test in another app

A third-party app issue can make it seem like the whole camera is broken.

Update social and camera-related apps from the App Store.
Test the camera in FaceTime or another trusted app.
If only one app fails, reinstall that app.

Method 5: Reset all settings if the camera still fails

This is the strongest non-destructive fix for update-related camera problems on iPhone.

Open Settings > General > Transfer or Reset iPhone > Reset.
Tap Reset All Settings.
Reboot the iPhone and test the camera again.

When to get service or support

If the iPhone 17 camera still does not work after these steps, back up your data and contact Apple Support. A camera that stays black in every app after iOS 26.3 may point to hardware failure.
