A faulty mobile camera can reveal itself in several ways, perhaps the screen stays black, the app crashes, photos look blurry, or error messages keep appearing. These signs can point to either software glitches or hardware faults, and recognising them is the first step towards finding a solution.
In this blog, we outline the practical steps you can take to diagnose the problem and get your camera working again. So, let us get started!
First Checks
Learn about the initial checks you should perform when your mobile camera is not functioning.
Restart The Phone and Test Again
Turn the phone off and on. It sounds basic, but a restart clears temporary glitches and often restores camera functionality. If you have a dual-camera phone, switch between front and back cameras to see if one works and the other doesn’t. If the camera app still shows a black screen or crashes, proceed to the following checks.
Close Other Apps and Remove Accessories
Close background apps that might be using the camera (video-call apps, QR scanners). Remove phone cases, lens attachments, or magnetic mounts; some accessories physically block the lens or interfere with the autofocus.
Software Steps that Often Fix Camera Problems
Learn about the software steps you can take to resolve camera issues.
Update Software and Apps
Make sure your phone’s operating system and the Camera app (or relevant third-party apps) are up to date. Manufacturers regularly fix camera bugs in updates, so installing the latest OS and app updates can resolve issues!
Check Permissions and Reset App Settings
Verify that the Camera app has permission to use the camera and microphone in your phone’s privacy settings. On Android, you can clear the Camera app cache or storage (this won’t erase your photos), which can remove corrupt temporary files. If a third-party app has recently started misbehaving, try uninstalling it or rebooting into Safe Mode to see if the camera works without it.
Run Any Built-In Diagnostics
Some phones include diagnostics or service menus that allow you to test the camera hardware. If your phone shows “camera error” messages, follow the on-screen guidance; save any important data before you try factory resets or deep repairs!
How to Clean Phone Camera Lens Safely (Step-By-Step)
A dirty lens is a prevalent cause of blurry or spotted photos. Here’s how to clean it without damaging the optics:
Power Off and Inspect
Switch the phone off and check the lens area under good light. Look for fingerprints, dust, grit, or cracked glass.
Clean with A Microfiber Cloth
Use a soft, lint-free microfiber cloth and gently wipe in one direction. Avoid using tissues or clothing that may scratch the surface. For stubborn grease, dampen the cloth slightly with a tiny amount of distilled water or a 70% isopropyl alcohol solution; do not pour liquids onto the phone. A blower (dust puffer) is good for removing loose particles first!
When The Glass Cover Is Cracked
If the protective glass over the camera is cracked or chipped, the lens beneath may be safe, but the glass will scatter light and spoil images. Replacing the cover or the whole module is usually required in that case (see the repair section below).
Diagnosing Hardware Issues
- The camera app shows a permanent black screen even after updates and restarts.
- Both front and rear cameras fail in all apps (including third-party apps).
- Visible physical damage (cracked lens cover, dents, water ingress).
- Overheating or moisture condensation inside the lens area.
If you see these signs, the issue is likely hardware and needs repair. Don’t open sealed phones unless you’re experienced; you risk voiding the warranty or making the problem worse!
How to Repair A Phone Camera
Read about how to repair a phone camera. Go through these safe options and cautions that you need to follow:
Professional Repair Vs DIY
For minor issues, such as a scratched camera cover, some people replace the glass using a kit. For more complex issues, such as sensor faults, torn flex cables, or water damage, consult a professional. Authorised repair centres use genuine parts and preserve warranties; independent shops may be cheaper, but be sure to check reviews and the quality of their parts.
You will find some step-by-step teardowns showing how camera modules are replaced, but those guides assume technical skill and specialised tools.
When to Consider a Repair Shop
If you’ve run the basic software fixes, cleaned the lens, tested across apps, and the camera still fails, it’s time for a professional repair. Look for a reputable local shop with clear guarantees and parts return policies.

Quick Dos and Don’ts
Please look over these dos and don’ts you should follow:
Do
- Back up your photos before attempting major resets or repairs.
- Use a microfiber cloth and a blower for cleaning.
- Try software fixes (such as restarting, updating, or clearing the cache) first.
Don’t
- Don’t pour liquids or spray cleaners directly on the lens.
- Don’t force the phone open if you lack the right tools and experience.
- Don’t ignore warranty options; authorised service is often the safest route.
FAQs
1. Why is my phone camera not working after an update?
Updates can occasionally introduce bugs or change drivers. Try restarting, checking for subsequent patches, and, if needed, rolling back or resetting settings after backing up data!
2. Can cleaning the lens really fix blurry photos?
Yes, fingerprints, dust, and smudges often cause blur and spots. A careful cleaning with a microfiber cloth usually helps!
3. What if the Camera app won’t open at all?
Force-close the app, clear its cache (Android), or restart the phone. If the app still won’t open, check for system updates or test another camera app!
4. Is water damage repairable for a camera?
Sometimes, but water can corrode connectors and sensors. Immediate power-off, drying, and professional inspection improve the chance of repair. Don’t attempt to charge a wet phone.﹚
5. Can I replace the camera glass myself?
Kits exist, but replacing the glass requires care: remove all fragments, avoid touching the lens, and use the correct adhesive. If unsure, seek a technician!
6. Why are photos showing weird lines or dots?
That could be dust on the sensor, a failing sensor, or physical damage to the lens cover. A professional diagnosis is usually needed!
7. Will a factory reset fix camera problems?
A factory reset can resolve deep software issues, but back up all data first. Use this only after all other steps have failed.
8. How long does a camera repair usually take?
Simple fixes (lens cover replacement) can be same-day; sensor or module replacements may take longer, depending on parts availability and warranty checks.
Final Thoughts
A camera that stops working is stressful, but most issues fall into two categories: software glitches or hardware damage. Start with simple checks, such as restarting, updating, closing apps, checking permissions, and cleaning the lens. Then, proceed to diagnostics and professional help if the fault persists.
