Quick checks first
- Clean the lens. Fingerprints and pocket grime make photos soft and hazy, and light sources flare. Wipe each lens with a clean microfibre cloth (a glasses cloth is ideal). Avoid paper towel and your shirt: they can scratch.
- Take off the case and any lens protector. A case edge or a cheap camera protector can block part of the image, cause haze, or create rings of light at night.
- Tap to focus. Tap the subject on the screen. If it sharpens, the camera works; it was focusing on something else.
- Try each lens. Switch between 0.5×, 1× and 2× or more, and the front camera. If only one is blurry or black, that lens is the problem.
- Restart the phone and close the camera app fully. A frozen camera app can show a black screen.
- Try another camera app (Instagram, WhatsApp or a video call). If the camera is black or blurry everywhere, it's hardware.
What a damaged camera looks like
| What you see | Likely cause |
|---|---|
| A haze or soft patch in the same place in every photo | A scratched or cracked lens cover (the small glass window over the lens) |
| Rings, streaks or flare around lights | A cracked lens cover, a dirty lens protector, or a scratch |
| It won't focus, keeps "hunting", or focuses only up close | Damage to the camera's autofocus |
| The image shakes or jitters, or you hear a buzz or rattle near the camera | Damage to the image stabilisation |
| Black screen on one lens, or "camera not available" | A failed camera module or its connection |
| Dust or a spot visible inside the lens | Dust got in through a crack in the lens cover |
The motorbike problem
Apple warns that mounting an iPhone on a high-power motorcycle can damage its camera. Strong vibrations, carried through the frame and handlebars, can degrade the optical image stabilisation and autofocus systems over time, which shows up as blurry photos and video. Apple suggests not mounting iPhones on high-power motorcycles, and using a vibration-dampening mount on mopeds and scooters, without leaving the phone there for long periods. The same physics applies to other brands' cameras with stabilisation.
Cracked lens cover or broken camera?
The lens cover is the glass window over each camera. It often cracks when a phone lands on its back, especially without a case, while the camera behind it is fine.
- Only the cover is cracked: on many phones it can be replaced on its own, which costs less than a new camera. Replace it soon: a cracked cover lets in dust and moisture, which do reach the camera.
- The camera itself is damaged (focus, stabilisation, black screen): the camera module is replaced. On most phones it's one part per lens, so only the faulty one needs replacing.
- The back glass is cracked too: see whether cracked back glass is worth fixing. On many models the camera lens covers are part of the back glass.
A note on iPhones
On iPhone 12 and later, iOS records camera repairs in Settings → General → About → Parts and Service History. A camera that isn't genuine Apple, or wasn't paired by Apple's own process, shows as an unknown part there. The camera still works. Some iPhone features that rely on calibration with the original camera can behave differently after a repair, so ask about this before any camera repair on a recent iPhone.
Protecting the camera
- A case with a raised rim around the cameras keeps the lens covers off the table and takes the knock in a fall.
- A good-quality lens protector, kept clean, guards against scratches; a cheap or dirty one causes the haze it's meant to prevent.
- On a motorbike, keep the phone in a pocket or bag, or use a mount with vibration damping.
