Direct answer
The moisture/debris warning blocks wired charging to protect the USB port. Drying naturally and testing another cable is safer than heat, compressed air or inserting objects.
What this covers
- The observed symptom matches this record
- Customer-accessible settings, connections and external components
- Diagnosis before reset, deletion or component replacement
What it does not cover
- ×A model-specific error code with a different documented meaning
- ×Internal electrical, battery-cell, gas, refrigeration or sealed-component repair
- ×A guarantee that every model exposes the same control label
Capture the exact symptom
ReversibleDisconnect the cable and inspect for actual liquid, lint, corrosion or a wet/damaged plug.
Run the smallest isolation test
ReversibleLet the phone and cable dry separately in moving room-temperature air, then test a clean known-good cable.
Correct only the proven cause
ReversibleClean only loose external debris with the device off using manufacturer-safe guidance; use wireless charging if supported while the port dries.
Verify before changing anything else
ReversibleReconnect after several dry hours and confirm the warning stays gone through one charge.
