Water damage may not be obvious during a short inspection. Buyers should look for physical, camera, charging and reliability warning signs.
Inspect the ports
Look for corrosion, residue and unusual discoloration.
Check camera lenses
Fog or internal moisture can indicate liquid exposure.
Test charging and speakers
Intermittent charging or distorted sound can appear after corrosion.
Check buttons and biometrics
Unreliable buttons and sensors can be a warning.
Ask about repair history
A professional repair record is better than a vague statement.
Price the risk correctly
Hidden liquid damage can become an expensive main-board failure.
