determining if iPhone has come into contact with liquid contamination – check water damage

Liquid Contact Indicators (LCIs)

Phone 5 is equipped with one external LCI to assist with determining if iPhone has come into contact with
liquid. A triggered LCI indicates that the iPhone may have come into contact with liquid.
When a phone comes into contact with liquid, a red color fills a circle within the LCI. If the external LCI is
tripped, missing, or cannot be seen, open the device to check the two internal LCIs or check for other signs
contamination or corrosion.
Note: A flashlight, magnifying glass, or otoscope may be needed to view LCIs.
