Clean the lenses, remove an interfering case or accessory, restart and update the iPhone, then seek service if it remains blurry.
1
Distinguish blur from normal camera behavior
Test in Apple's Camera app in bright light with a stationary subject. Tap the subject to focus and hold the iPhone steady. Low light, movement, digital zoom, shooting too close, Portrait depth effects, or compression in another app can create blur even when the camera hardware works.
2
Clean every camera lens safely
Inspect the front and rear lenses for fingerprints, dust, moisture, or a protective film. Wipe them gently with a clean microfiber cloth. Do not use abrasive material or force liquid around the camera opening. Take another test photo after cleaning.
3
Remove cases and magnetic accessories
Remove the case, lens protector, magnetic mount, lens converter, or accessory and retest. Apple specifically warns that magnets near the rear camera can interfere with stabilization. Compare images with and without the accessory before deciding the camera itself is faulty.
4
Compare cameras, zoom levels, and apps
Take separate photos with the front camera and each available rear-camera zoom setting in Apple's Camera app. Note whether blur affects every camera or only one lens. If only a third-party app is blurry, update that app and check its own camera quality settings rather than deleting it immediately.
5
Restart and update the iPhone
Restart the iPhone using the normal shutdown controls for its model, then open Settings > General > Software Update and install a current compatible iOS update after backing up. Retest before changing more settings so you know whether the software step helped.
6
Arrange service for persistent hardware symptoms
Contact Apple Support if focus repeatedly hunts in bright light, the preview shakes without an accessory, one camera stays blurry, or the camera or flash fails after these checks. Keep sample photos and note which lens and apps are affected; that evidence helps diagnosis.
