Smartphone Camera "Focus Hunting" (Blurry Photos)
4.5
The camera keeps trying to focus but never locks on, resulting in blurry images.
Symptoms
- Blurry photos
- Focus motor noise
- Constant refocusing
Possible Causes
- Dirty lens
- Laser AF blocked
- OIS hardware failure
Step-by-Step Fix
1
Clean the Lens
Wipe the camera glass with a microfiber cloth to remove fingerprints.
2
Remove Case
Some cases block the Laser Auto Focus sensor (the small black dot near the lens).
3
Tap to Focus
Manually tap the subject on the screen to force the camera to lock focus.
When to See a Technician
If you hear a buzzing sound from the camera, the Optical Image Stabilization (OIS) is likely broken.
