iPhone camera not working or showing black screen
A black or unreliable iPhone camera can be caused by an accessory blocking the lens, a temporary software state, or a problem isolated to one camera module. Apple recommends removing cases/accessories, testing the camera and flashlight, restarting and updating iOS before service.
Remove obstructions and test Apple Camera
Remove any case, film or magnetic accessory that could obstruct the camera, test both front and rear cameras plus the flashlight, then restart and update iOS. If one or both cameras remain unavailable, service may be needed.
- Remove case, film, magnetic mount or lens accessory.
- Clean the lens.
- Test front and rear cameras and the flashlight.
Why this branch first: Apple recommends removing blocking accessories and testing the camera/flash first.

What this usually means
The useful first split is whether the problem affects one camera, both cameras, or only one third-party app. If the built-in Camera app works normally, the issue belongs to the other app or its permissions rather than the camera hardware.
What we verified from the source material
Apple’s camera guidance covers cases/accessories, lens cleaning, flashlight testing, restart, iOS update and service. It supports distinguishing built-in Camera failure from a one-app permission/problem before assuming hardware failure.
Prerequisites and checks
Prepare first
- Clean the lenses with a microfiber cloth.
- Save important data before service.
- If only one third-party app fails, check that app’s camera permission.
Checks that prevent the wrong fix
- Remove cases/accessories near the camera.
- Test front and rear cameras in Apple Camera.
- Test the flashlight and note whether one module alone fails.

Solutions, in order
Remove obstructions and test Apple Camera
- Remove case, film, magnetic mount or lens accessory.
- Clean the lens.
- Test front and rear cameras and the flashlight.
Why this can work: Apple recommends removing blocking accessories and testing the camera/flash first.
Restart, update and retest
- Restart the iPhone.
- Install the current supported iOS update.
- Retest both camera directions in Apple Camera.
Why this can work: Apple recommends restart and current iOS before service.
How to know the fix actually worked
- The built-in Camera app captures from both available cameras.
- The camera remains functional after restart.
Do not count a temporary disappearance of the symptom as a confirmed fix if the problem normally returns after a restart, reconnect or several minutes of use.
When not to keep changing things
- If the device is physically damaged, swollen, or excessively hot, stop testing and seek service.
Escalation: If camera/flash still fail in Apple Camera after restart and update, use Apple service rather than repeated third-party app reinstalls.
