Symptoms

  • Phone was exposed to water, humidity, or spilled liquid
  • Warranty or repair shop mentions a triggered LDI (liquid damage indicator)
  • Phone may be working fine or showing intermittent issues

Likely causes

  • CommonDirect water exposureA dunk, spill, or heavy rain exposure is the most direct cause.
  • PossibleHigh humidity environments over timeExtreme humidity (saunas, bathrooms) can occasionally trigger sensitive indicators.

What to do

  1. Understand that a triggered indicator alone doesn't always mean current damage, but it usually voids standard warranty coverage for liquid-related issues.
  2. Watch for developing symptoms: muffled speakers, corrosion smell, or charging problems over the following days.
  3. Let the phone fully dry if the exposure was recent, following standard water-damage drying steps.
  4. Avoid submitting an insurance or warranty claim expecting it to be covered as a non-liquid issue, since technicians check this indicator.
  5. If problems develop, go to a repair shop for an out-of-warranty repair rather than relying on the manufacturer's warranty.

When to call a pro

If symptoms appear after a triggered indicator, see a repair shop for an out-of-warranty diagnostic rather than assuming it's unrelated.
