Condensation or fog inside the phone camera lens

Symptoms

• Camera preview looks foggy or hazy overall
• Wiping the outside lens doesn't clear it
• Often follows moving between hot and cold, or after getting wet
• May clear on its own after time in a dry, warm place

Likely causes

• CommonRapid temperature change causing internal condensationMoving quickly from a cold to warm environment (or vice versa) can cause moisture to condense inside the camera housing.
• CommonWater exposure that got past sealsRain, splashes, or submersion can let moisture reach the inside of the lens assembly.
• PossibleHigh humidity environmentsExtended time in very humid conditions can lead to moisture buildup inside small gaps.

What to do

1. Power off the phone if you suspect water exposure caused this, to reduce the risk of a short.
2. Place the phone in a dry, room-temperature area with good airflow for at least 24–48 hours.
3. Avoid using rice, which doesn't effectively dry electronics and can add dust; silica gel packets work better if available.
4. Do not apply direct heat, like a hair dryer, which can damage internal components.
5. After drying fully, check if the fog has cleared before powering on and testing the camera.
6. If fog persists after thorough drying, professional disassembly and cleaning may be needed.

Tools and parts

• Silica gel packets (optional)

When to call a pro

See a repair shop for professional cleaning if fog remains after a full drying period, since moisture can lead to corrosion over time.
