Is the viewfinder black, or the entire phone display?
If you can still see the Camera controls, status bar, and other apps, this guide addresses a black camera preview. If the whole display is dark and the phone does not visibly respond, follow the separate iPhone startup and black-screen guide. The recovery paths are different.
Record whether the issue affects Apple's Camera app or one other app, the front or rear camera, and the torch. These observations are more useful than immediately resetting the device.

| Both cameras black in Apple's Camera app | Accessories, restart, iOS update, then Apple's camera diagnostics |
| Only one camera black | Switch cameras and record the failing side |
| Camera app works; one other app is black | That app's Camera permission and app state |
| The whole phone display is black | Startup or display troubleshooting, not this camera workflow |
Start with checks that do not remove photos
Apple advises removing cases, films, magnetic accessories and add-on lenses that may obstruct the camera or flash, then restarting the iPhone. If images are merely blurry, clean both lenses with a microfibre cloth. A completely black preview does not mean the photo library needs to be cleared.
After restarting, check for the latest iOS version offered to this device. Back up through the normal update workflow, then open Apple's Camera app and test a photo with each camera. Apple's camera article does not instruct you to erase the phone or reset every setting.
- Remove any accessory or film that could block a lens.
- Restart the iPhone.
- Check Settings → General → Software Update, then update after backing up.
- In Camera, switch between front and rear cameras and take a test photo.
If only another app fails, check Camera permission
If Apple's Camera app works but a scanner, social, or meeting app shows a black preview, open Settings → Privacy & Security → Camera. Apple says this list shows apps that have requested camera access; review the affected app's permission.
If permission is already enabled, update that app and note whether the problem remains limited to it. An app-only failure is not by itself evidence that the camera hardware is broken. Check with an administrator before changing policies on a managed phone.
Test the torch separately from Camera flash
Open Control Centre and try the torch. Apple includes that check in flash troubleshooting. If flash only works sometimes in photos, check whether Camera is set to Flash Auto rather than assuming a hardware fault.
Record both the torch and camera results for a service visit. A working torch cannot prove that every camera component is healthy. Apple also notes that some camera functions may pause temporarily when the device gets too hot; allow it to return to a suitable temperature first.
Use Apple's diagnostic path if the preview stays black
Apple's camera support article, updated in October 2026, describes iOS Diagnostics for a black camera screen: turn the device off, hold the side button while it starts to open Recovery Assistant, choose Diagnostics Mode, then run Mobile Resource Inspector when prompted. Follow the on-device prompts if this path is available on your model and iOS version.
If the diagnostic finds a problem, or basic checks do not restore the camera, contact Apple or an authorized service provider. Diagnostics Mode is different from selecting Restore on a computer; this guide does not ask you to erase the iPhone. Keep a usable backup and record which camera, flash, or app failed.
- Record the model, iOS version, affected camera and torch result.
- Follow Apple's current Recovery Assistant instructions to enter Diagnostics Mode.
- Run Mobile Resource Inspector and keep the result.
- Arrange service if it finds a problem or the issue persists; do not erase first.
