What’s wrong with your iPhone?
🔊 Muffled or Crackling Sound ⚡ “Liquid Detected” Warning / Won’t Charge 🖥️ Screen is Dim or Totally Black 📺 Green Lines on the Screen 📳 Screen is Flickering or Jittery 🔌 Won’t Turn On / No Power 👤 Face ID Isn’t Working 👆 Touchscreen is Unresponsive 📡 No Signal / “Searching…” 🔋 Battery is Hot or SwollenHow to Tell if Your iPhone Has Water Damage
The symptoms above are strong evidence, but there’s one definitive check: the Liquid Contact Indicator. On iPhone models with a physical SIM tray, a small indicator sits inside the SIM card slot. Eject the tray and shine a light into the slot — the indicator is white or silver when the phone is dry, and it turns red after contact with water or liquid. Red means water got inside, so the symptoms you’re seeing are almost certainly water damage.
Note: eSIM-only models (like US iPhone 14 and later) have no SIM tray, so there’s no indicator you can check yourself — go by the symptoms above instead.
When Do Water Damage Symptoms Appear?
It depends on where the water reached. The “Liquid Detected” warning and muffled sound usually show up within minutes, while deeper problems — a dim screen, flickering, or no power — often surface over the next 24 to 48 hours as moisture spreads inside. And because droplets shift around as you move the phone, a symptom can disappear and come back later. That’s why the first 48 hours are critical.
2. Fixes for Each Water Damage Symptom
Every symptom above has a dedicated guide that breaks down the cause and the step-by-step fix for that specific water damage problem.

What to Do About a “Liquid Detected” Warning
How to get rid of that annoying alert and what to do when you can’t charge your phone.
★★ High DemandiPhone Won’t Turn On After Water Damage
What to do if it still won’t boot up after 24 hours of drying. Includes force restart steps and when to call it quits.
Dealing with a Hot or Swollen Battery
This one’s serious. We’ll explain why you need to stop using your phone immediately if this happens.
⚠️ Safety AlertScreen Glitches
Fixing a Dim or Completely Black Screen
Usually caused by water getting into the backlight circuit. Sometimes it just needs to dry out.
★★How to Fix Green Lines on the Screen
A classic symptom for OLED displays. This one almost always means you’ll need a screen replacement.
What to Do If Your Screen is Flickering
Could be water messing with the touch IC. If it doesn’t stop after drying, it’s repair time.
Other Common Issues
Troubleshooting Face ID Not Working
Water near the TrueDepth camera is the likely culprit. Good news: it often starts working again after it dries.
Fixing an Unresponsive Touchscreen
If only part of the screen is dead, it’s the digitizer. If nothing works, you’ll probably need a repair.
How to Fix No Signal or “Searching…”
Water might have gotten near the antenna. Try checking your SIM card and restarting after it’s dry.
3. What If You Have Multiple Symptoms?
Seeing two or more of these problems at once? That’s a bad sign. It likely means water has gotten deep inside your iPhone.
Multiple symptoms usually point to motherboard damage. Trying to fix it yourself could make things worse. Your safest bet is to get it to a repair shop.

5. Frequently Asked Questions
Muffled or crackling sound is #1 — water trapped in the speaker grille is the most common problem immediately after a dunk. The “Liquid Detected” charging warning is a close second, followed by screen issues like dimming, flickering, and green lines. Most symptoms appear within 24–48 hours of getting wet.
Because there’s still water sloshing around inside. As you move your phone, a droplet can shift, shorting out a different component. It’s a clear sign that your phone isn’t dry yet.
Sometimes, if it’s minor. But water trapped in the fine speaker mesh has a tough time evaporating on its own. You’ll get way better results by actively pushing it out with a sound-based tool like WaterKick.
It’ll stick around until the Lightning or USB-C port is completely dry, which usually takes 24 to 48 hours. You can speed it up by leaving your phone in a well-ventilated spot. Don’t try to bypass it and charge while it’s wet—that’s a recipe for disaster.
Give it about two or three days. During that time, try a water eject tool a few times. If things aren’t getting better, it’s time to think about a repair. If a problem is still there after a week, it’s probably not going away on its own.
