Xiaomi phone fell into the water and shows headphones: why there is no sound and how to fix it

You dropped a Xiaomi smartphone into the water, and after drying, suddenly there was an icon of connected headphones on the screen, even though there were none - and the sound was gone? This problem occurs in Redmi Note 10/11/12, POCO X3/X4 and other devices of the brand after contact with moisture, the reason lies in the short circuit of the contacts of the Type-C connector or audio chip, as well as software failures.

In this article, we’ll look at step-by-step steps to diagnose and troubleshoot things, from drying and cleaning the connector to resetting and flashing. You’ll also learn why even after the phone has completely dryed, the headphone icon can stay on screen because of chip oxidation, and what to do if standard methods don’t work. Importantly, some steps require disassembling the device — if you’re unsure of your skills, you’d better go to a service center.

Why Xiaomi shows headphones after water and there is no sound?

The ingress of moisture into the smartphone triggers a chain reaction of problems that lead to a false alarm of the headphone sensor.

• 💧 Short circuit in the Type-C connector: water conducts electricity, which makes the system "think" that the headphones are connected. Even after drying, oxidized contacts can retain a false signal.
• 🔌 Audio chip damage: Xiaomi models with Qualcomm Snapdragon (such as the Redmi Note 10 Pro) have an audio track controlled by a separate chip that is sensitive to moisture.
• 🖥️ Firmware failure: system MIUI can misinterpret signals from damaged contacts, fixing the "connection of headphones" at the software level.
• 🔊 Oxidation of speakers: if water gets under the speaker grid, it can block the sound, and the system compensates for this by switching to "earphones".

Interestingly, some users have a problem a few days after moisture is injected, due to the slow oxidation of the contacts. For example, in POCO F3, it is often the right speaker who suffers, since its contacts are closer to the charging connector.

First steps: what to do immediately after water hits

Don't panic, but act fast, and it depends on the first few minutes if you can save your phone without repair.

1. Turn off the phone (press the power button for 10 seconds if the screen is not responding) and this will prevent short circuits.
2. Extract. SIM-card and memory card – they can block the evaporation of moisture.
3. Do not shake the device - water can penetrate deeper inside.
4. Do not turn on your phone for at least 24 to 48 hours, even if it is “on”.

⚠️ Warning: Never use a hair dryer or microwave to dry! Hot air can warp plastic parts and speed up oxidation. Also avoid "folk methods" like burying your phone in rice - this is inefficient and can clog the connectors with dust.

How to Dry Your Phone Properly: Step-by-step Instructions

Effective drying requires a holistic approach. Here's what really works:

1. Remove visible moisture: 🧻 Wipe the case with a microfiber wipe (not a paper towel - it leaves the pile!). 🔦 Light the Type-C connector with a flashlight – if drops are visible inside, gently wet them with a cotton swab (not a metal object!).
2. Use the absorbents: 📦 Put your phone in a sealed bag of silica gel (boxes of shoes or electronics) and change them every 6 to 8 hours. 🚫 Avoid rice – it absorbs moisture too slowly and can clog connectors.

Create an airflow

• 💨 Place the phone in front of the fan at a minimum speed (30–50 cm distance) for 12–24 hours.
• 🔄 Every 2-3 hours, change the position of the phone (for example, put the screen up, then down).

Special procedures can be used to speed up the process. UV-lamps (for example, for drying nails), but you need to keep the phone under them for no more than 10-15 minutes with breaks.°C.

Cleaning the Type-C connector: how to remove the oxidation of contacts

If the headphone icon didn't disappear after drying, it's likely that the contacts of the connector have oxidized.

• 🧴 Isopropyl alcohol (90%+) — It evaporates without a trace and dissolves oxides.
• 🎨 Soft brush (for example, for watercolors) or cotton swabs.
• 🔦 Lighting lamp for the connector.

Step-by-step cleaning:

1. Wet the brush in alcohol and gently walk through the contacts of the connector (movements should be parallel to the board, not deep!).
2. Allow the alcohol to evaporate completely (10-15 minutes).
3. Repeat the procedure 2-3 times if the oxidation is strong (the contacts will have a greenish or white coating).

⚠️ Warning: Do not use vinegar, citric acid or acetone - these can damage the coating of contacts. Also avoid metal objects (needles, paperclips) so as not to close the chain.

After cleaning, check the connector for moisture with a flashlight. If the contacts are shiny and have no plaque, you can try turning on the phone.

💡

To prevent oxidation after cleaning, apply a thin layer of silicone lubricant (such as WD-40 Specialist) to the connector contacts, which will protect them from moisture in the future.

Software methods: resetting settings and disabling headphones in MIUI

If hardware cleaning didn't work, the problem could be at the firmware level. There are several ways in MIUI to trick the phone into forgetting about the connected headphones.

Method 1: Forced deactivation of headphones through the engineering menu

This method works on most Xiaomi models (except Black Shark).

1. Open the phone app and dial the code: ##3644633##
2. Select Hardware Testing → Audio → Headset Mode.
3. Press Headset Switch and select Off.
4. Reboot the phone.

If the code doesn’t work, try an alternative for newer versions of MIUI:

##4636## → Tests → Audio → Turn off headphones

Method 2: Resetting the sound settings

Sometimes it helps to reset only audio settings without losing data:

1. Go to Settings. → Sound and vibration → Additionally (⋮) → Resetting the sound settings.
2. Confirm the reset and restart the phone.

Method 3: Complete reset (Hard Reset)

If nothing helps, you will have to make a complete reset (all data will be deleted!):

1. Turn off the phone.
2. Press Volume Up + Power before the Mi logo appears.
3. From the Recovery menu, select Wipe Data → Wipe All Data.
4. Confirm the action and wait for the reboot.

⚠️ Warning: After resetting, the phone will require you to enter a Mi Account if the protection was previously activated!

💡

If after the reset the problem remained - the reason is precisely in the hardware malfunction (oxidation of the chip or damage to the board).

What if there is no sound even after all the manipulations?

If neither drying, cleaning, or dumping has helped, it is likely to be damaged:

• 🔧 Audio chip (a common problem with Redmi Note) 8/9 water-water).
• 🔊 Dynamics (oxidation or rupture of the membrane).
• 📱 Footprints connecting the motherboard to the Type-C connector.

Here are the estimated prices for replacement of components in service centers (for Moscow, 2026):

Before repairing, check your phone for hidden damage:

• 🔋 Check if the battery is swelling (it is dangerous!).
• 📶 Make sure all antennas (Wi-Fi, mobile network) are working).
• 🔄 Check charging – if the phone isn’t charging, the problem may be in the power controller.

💡

If you decide to repair the phone yourself, buy a BGA soldering kit (like Quick 861DW) and use a low-activity flux (like Amtech NC-559-V2) to clean the board.

How to prevent re-entry of moisture: tips for Xiaomi

Even if you've managed to repair your phone, the risk of re-injury remains, and here's how to minimize it:

• 🛡️ Use a sealed case with certification IP68 (For example, Spigen Rugged Armor or UAG Pathfinder).
• 🚿 Avoid using your phone in the bathroom, pool or in the rain.
• 🔌 Close the Type-C connector with a special plug (sold with some cases).
• 📱 Check the moisture indicator regularly (white circle under the tray) SIM-cards - if it turns red, moisture gets inside).

For Xiaomi models with official IP53 protection (such as the Redmi Note 12 Pro+), remember that this certification only protects against splashes, not from full immersion.

If you are often in high humidity (such as exercising or working outside), consider buying a waterproof pouch case (such as the Lifeproof Fre) that completely insulates your phone from water, but requires removal to charge.
