Water damage is one of the most common and expensive problems for smartphones. Whether you’re buying a used phone or suspect your own device might have taken an unexpected splash, being able to identify water damage is essential. A water-damaged phone can lead to slow performance, unresponsive screens, or complete device failure. This guide explains how to identify the signs of water damage and what you can do if your phone has been exposed to moisture.
Common Signs of Water Damage in Phones
1. Corrosion or Discoloration on Ports
Start by inspecting all physical ports such as the charging port, headphone jack, and SIM tray. If there’s any visible corrosion, greenish tint, or white residue, that’s a clear sign of water exposure.
Tip: Use a flashlight to get a better view inside the ports. Even slight discoloration can indicate damage.
2. Foggy Camera Lens or Display
Water that enters your phone can create internal condensation. If the front or rear camera lens appears foggy or blurry without reason, moisture might be trapped inside. Similarly, if the screen has cloudy patches or appears hazy, it’s likely due to water.
3. Unusual Screen Behavior
If the screen becomes unresponsive, starts ghost-touching, or shows vertical lines and flickering, it may be a result of water damage. These issues occur when moisture affects the touch sensors or display connections.
4. Sudden Battery Drain or Overheating
Water damage often disrupts the battery’s function, causing the phone to heat up abnormally or the battery to drain quickly. If your device worked fine before and suddenly starts overheating with low screen time, suspect water interference.
5. Rusted SIM Tray or SD Card Slot
Eject the SIM tray and look for rust or swelling. Water corrosion affects these metal parts quickly. Also, inspect any SD card inserted—if it’s warped or rusted, water has likely entered that area.
6. Speaker or Microphone Distortion
If your voice sounds muffled during calls or the speaker sounds crackly, water might have reached these components. Water affects the vibration of speaker membranes and can block the mic’s small sound channels.
7. Non-Functional Buttons or Charging Issues
When internal circuits are affected by moisture, physical buttons like the power button or volume rocker may stop responding. Similarly, the phone may fail to charge or display a “moisture detected” warning if water has entered the charging port.
Using the LDI (Liquid Damage Indicator)
Most modern smartphones—both Android and iPhone—include a Liquid Damage Indicator (LDI). This is a small sticker placed in the SIM tray slot or near internal components that changes color when exposed to water.
For iPhones:
Apple places the LDI in the SIM card slot. It is normally white or silver, and turns red or pink when water touches it.
For Samsung or Other Android Devices:
Check near the battery compartment (if removable) or within the SIM/memory card slot. The same color change rule applies.
This is one of the most reliable indicators to check for water damage.
What to Do If You Suspect Water Damage
1. Turn Off the Device Immediately
Do not try to use or charge the phone. Powering a wet device can lead to a short circuit, worsening the damage.
2. Remove Accessories and Dry the Exterior
Remove the phone case, SIM card, memory card, and any other accessories. Use a dry cloth to wipe off any visible moisture. Avoid using heat like a hairdryer as it can push moisture deeper into the device.
3. Use Silica Gel (Not Rice)
Contrary to common belief, placing a phone in rice is not the best option. Silica gel packets (like those found in new shoes or electronics packaging) are more effective at absorbing moisture.
Place the phone and silica packets in an airtight container and leave it for 24–48 hours.
4. Visit an Authorized Service Center
Even if your phone appears to be working fine, internal corrosion may still be occurring. Have it opened and cleaned professionally to prevent long-term issues.
Preventing Water Damage
- Use a water-resistant phone case.
- Avoid using phones in rain or near water sources like pools or kitchens.
- Don’t charge a phone if it’s even slightly wet.
- Choose phones with an IP rating (IP67 or IP68) for water resistance.
Conclusion
Knowing how to spot water damage in phones is crucial—especially in Pakistan where humidity, rain, and accidental spills are common. Whether you’re checking a secondhand phone or trying to rescue your own device, catching the signs early can save you from bigger problems down the line. Always handle potential damage promptly, and when in doubt, get it inspected by a technician.
