the Liquid Contact Indicator (LCI) on an iPhone can change color to red very quickly after exposure to water:
- The search results state that when the LCI encounters water, it changes from white to red. This process happens because the white coating on top of the sticker melts, revealing the red color underneath[2].
- One search result mentions that the LCI will quickly change color from white to red once exposed to water or other liquids[3]. No specific timeframe is provided, but the implication is that it happens rapidly.
- The search results do not indicate that there is a delay before the LCI changes color. The color change appears to be an immediate reaction to water contact.
So in summary, while an exact time is not specified, the search results suggest that the LCI on an iPhone can turn red within a very short period of time, likely within seconds or minutes, after the iPhone is exposed to water. The color change is described as quick and immediate, not a gradual process.
