Common Symptoms of S21 Charging Port Problems
- Loose or wobbly cable connection
- Charging only at certain angles
- Fast charging not working
- Device not recognised when connected to PC
- “Moisture detected” warnings even when dry
Step 1: Verify Charger and Cable
Many UK users overlook accessories. Test with:
- Original Samsung USB-C charger (25W or 45W Super Fast Charger)
- Certified USB-C cable
- Different UK wall sockets to rule out loose or faulty plugs
Step 2: Inspect the Port for Debris
Common in cities like Manchester and Glasgow, lint or dust often blocks proper contact. Use a torch to inspect the port carefully.
Safe Cleaning Steps:
- Turn off your Samsung S21 completely.
- Gently remove debris with a wooden or plastic toothpick.
- Blow out remaining particles with short bursts of air.
- Avoid metal tools which can bend pins or damage contacts.
Step 3: Check for Moisture or Corrosion
UK weather often introduces moisture into the port. In humid cities like Newcastle, Bristol, and Leeds, moisture warnings are common. Leave the phone upright in a dry room for 45–60 minutes, avoiding rice or silica unless manufacturer-approved.
Step 4: Software Troubleshooting
- Restart in Safe Mode: Power + Volume Down → Power Off → Safe Mode
- Update device: Settings → Software Update → Download and Install
- Close or uninstall apps that may interfere with charging
Step 5: Test Wireless Charging
If wireless charging works normally, the port hardware is likely at fault and may require professional repair.
