Water detection problem

Many (including mine) Samsung Galaxy S23 Ultra users have reported the “Moisture detected in charging port” error after a software update, even when the phone hasn't been near water. This seems to be a software-related bug, though in rare cases it may be hardware-related.

How to Fix the Moisture Detection Error (Step by Step)

1. Check for Actual Moisture

Just to be sure:

Use a soft, dry cloth to gently wipe the port.

Leave it to air-dry for 30 minutes, or use a cool fan (no heat!).

Do NOT insert cotton swabs or blow hard into the port — it may push moisture/dust in further.

2. Clear USB Settings Cache

A corrupted USB settings cache may trigger this bug.

1. Open Settings > Apps

2. Tap the 3 dots (⋮) and choose Show system apps

3. Search and select USB Settings

4. Tap Storage > Clear Cache and Clear Data

5. Restart your phone

3. Force Stop Android System & Restart

This resets charging and detection functions.

1. Go to Settings > Apps

2. Tap 3 dots > Show system apps

3. Find and tap Android System

4. Tap Force stop

5. Restart your phone

4. Try Safe Mode

To check if the issue is caused by third-party apps:

1. Hold power button > Tap and hold "Power off" > Select Safe Mode

2. In Safe Mode, plug in your charger and see if the message appears.

3. If it doesn’t, a third-party app may be interfering.
