Check these first
Do not assume the cause from the symptom alone. First determine whether the issue affects the whole phone, one app, one connection, or one accessory. Work from low-impact checks toward recovery or repair.
- Compare the built-in Camera app with another trusted app that uses the camera
- Switch between front and rear cameras
- Inspect lens dirt, the case, lens protectors, and magnetic accessories
Critical diagnosis for this symptom
Compare the stock camera with another app, front and rear cameras, storage, and heat.
Internal fogging or abnormal noise after impact should be escalated to repair.
Escalate with device, OS, error, and reproduction details when the issue persists after restart, controlled comparison, and update checks, or when physical damage, abnormal heat, account suspension, or carrier provisioning is suspected.
Narrow down the cause
| Scope of the issue | Where to check next |
|---|---|
| Only one app is affected | Check app permissions, updates, storage, cache, and reinstall options |
| The whole phone is affected | Check restart, system updates, free storage, and system settings |
| Other devices have the same issue | Check the network, service, charger, or accessory |
| The issue began after a drop or liquid exposure | Avoid repeated power or charging attempts and contact official support |

Safe step-by-step process
Complete one step at a time and test after each change. Do not change several settings at once.
- 1Fully close the Camera app and other video-call, QR, or social apps that may be using the camera, then reopen it.
- 2Clean the lens surface with a soft dry cloth and temporarily remove the case or lens cover.
- 3Review camera permissions. If only one app fails, revoke and re-enable its permission before testing.
- 4Restart the phone and update the operating system and affected apps.
- 5Check free storage so the phone can save photos. On Android, clear the Camera app cache if the manufacturer supports it.
- 6Seek repair if one camera stays black, the module makes unusual noise or vibration, or the issue began after impact.
Actions to avoid
- Hitting the camera area to restore focus
- Granting every app camera access without review
- Deleting large photo libraries without confirming backups
Prevent the issue from returning
- Keep the lens clean and avoid poorly fitted lens covers
- Check available storage and cloud-sync status before important recording
Frequently asked questions
What if my screen looks different?
Menu names and locations vary by OS, manufacturer, model, region, and software version. Use the Settings search field and check the manufacturer guide for your exact model.
When should I stop troubleshooting?
Stop as soon as the issue is fixed. Change one setting at a time so you can identify what solved the problem and reverse it if necessary.
What should I do if the issue remains?
Record how to reproduce it, verify your backup, and contact the manufacturer, carrier, or app provider most closely related to the problem.
