Xiaomi phone thinks headphones are connected - why and how to fix it?

You've turned on music on a Xiaomi smartphone, but the sound instead of speakers stubbornly goes into "invisible" headphones? Or vice versa - connected the headset and the device does not recognize it, showing the headphone icon on the notification panel? This problem is familiar to many owners of Redmi, POCO and Mi phones - from the budget Redmi Note 8 to the flagship Xiaomi 13 Ultra. Most often, it is not the 3.5 mm connector itself (if it is), but software failures or contamination of contacts.

In this article, we’ll look at all the possible reasons Xiaomi misidentifies headphone connectivity, from moisture to damage to the motherboard plume. You’ll get step-by-step photo instructions for each repair method, including hidden developer settings and hardware tests. And if the hardware problem is, you’ll know how much repairs will cost at the service center and whether you can handle it yourself.

Why does Xiaomi show connected headphones when they are not?

The Xiaomi headset recognition error is caused by a headphone detection circuit failure, which in modern smartphones is not only the physical connector (if any) but also the software controller, and here are the main reasons:

• 🔌 Pollution or oxidation of contacts in the connector 3.5 mm (dust, moisture, rust).
• 📱 Software failure in service media.audio_flinger sound-driver.
• 🔧 Damage to the plume of the audio jack or motherboard (often after falls).
• 🔄 Firmware conflict after update MIUI (particularly ROM).
• 🎧 Failure of the headset itself (if the problem occurs only with specific headphones).

On models without a 3.5mm connector (such as the Xiaomi 12 Pro or POCO F4), the error may occur when USB-C headphones or adapters are connected, in which case the Type-C controller is to blame for the incorrect type of connected device.

How to check if it is a hardware problem or a software problem?

Before you put your phone on the service, do a diagnostic to see what's going on.

1. Restart your smartphone – sometimes the error disappears after the reboot.
2. Try other headphones – if the problem remains, it’s not the headset.
3. Turn on the "In the plane" mode for 10 seconds, then turn off.
4. Check the connector with a flashlight - whether there are any debris or bent contacts inside.

If after these manipulations the icon of the headphones has not disappeared, proceed to the hardware check:

⚠️ Warning: If your phone falls or gets wet, don't try to clean the connector with wet wipes, this will aggravate corrosion. Use only isopropyl alcohol (90%+) and cotton-stick.

Method 1: Cleaning the 3.5mm connector (if any)

In 80 percent of cases, the problem is solved by a simple contact cleanup.

• 🔦 Lantern (for lighting the connector).
• 🧴 Isopropyl alcohol (not vodka!).
• 🧼 Cotton swabs or toothpick.

Step-by-step:

1. Turn off the phone.
2. Illuminate the connector with a flashlight - look for debris, oxidation or bent contacts.
3. Wet the cotton swab in alcohol and gently wipe the internal contacts (don't press!).
4. Let the connector dry for 10-15 minutes.
5. Turn on the phone and check the sound.

Repeat the procedure with a new cotton swab |

Try blowing the connector with compressed air |

Check the headphones on another device |

Reset the sound settings-->

If the problem persists after cleaning, it is possible that the connector contacts are closed (for example, due to fluid intake), in which case only replacing the connector or drying in the service center using an ultrasonic bath will help.

Method 2: Resetting sound and cache settings

If the problem is software, resetting the audio system will help, a method that works on all Xiaomi models, including the Redmi 9, POCO X3 and Mi 11.

Instructions:

1. Open the Settings. → Sound and vibration.
2. Slip on the additional settings (or “More”).
3. Select Resetting Sound Settings.
4. Confirm the action.

If the reset didn't help, clear the cache of apps related to the sound:

1. Go to Settings → Applications → Application Management.
2. Find and open Media (or AudioFX, Bluetooth).
3. Press Warehouse. → Clear the cache.
4. Reboot the phone.

💡

Some MIUI firmwares have hidden the sound reset, and to find it, type "reset" in your settings search.

Method 3: Use of the Engineering Menu (MTK/Qualcomm)

For advanced users, there is a way to diagnose through an engineering menu, which is available on all Xiaomi, but the commands vary depending on the processor.

For smartphones on Qualcomm (most models):

#4636## → Select Audio → Check the status of Headset

For smartphones on MediaTek (rarely, for example, Redmi 8A):

##36446337## → Hardware Testing → Audio → Headset

In the engineering menu, pay attention to the parameters:

• 🔊 Headset Status – Must be 0 (no headphones) or 1 (have headphones).
• 🔌 Headset Impedance: Resistance. If the value jumps, contacts are closed.

⚠️ Warning: Do not change other options in the engineering menu unless you understand their purpose! This can lead to loss of network or damage to speakers.

Method 4: Resetting the firmware or resetting to factory settings

If the problem occurred after the MIUI update, the fault may be a bug in the new firmware version, in which case it will help:

• 🔄 Retraction to the previous version MIUI (via Fastboot or Recovery).
• 📱 Reset to factory settings (deletes all data!).
• 🛠️ Install custom firmware (e.g. Pixel Experience or LineageOS).

How to reset settings (without data loss):

1. Make a backup in Settings → Additional → Backup.
2. Go to Settings → About the phone → Reset settings.
3. Select Settings Reset (not “Delete all data!”).
4. Confirm the action.

If the reset didn't work, try flashing your phone through the Mi Flash Tool.

1. Download the official firmware for your model from the Xiaomi website.
2. Install the Mi Flash Tool on your PC.
3. Connect your phone in Fastboot mode (clamp Volume down + Power).
4. Select the firmware file and press Flash.

💡

Before you run the firmware, check if the bootloader is unlocked. If not, request unlocking on Xiaomi's website, it will take up to 7 days.

Method 5: Hardware repair (replacement of connector or plume)

If all the software methods didn't work, the problem is 100% hardware, and you're going to have to:

• 🔧 Replacement of the audio jack 3.5 mm (cost: 500-1500) ₽).
• 📱 Repair/replacement of the plume (if the track on the board is damaged).
• 🔨 Interconnection (with oxidation or breakage).

Cost of repairs in service centers (2026):

If you decide to repair yourself, buy an original connector for your model (for example, for the Redmi Note 10 Pro, a part labeled Xiaomi 2101119SG will suit).

• 🔨 Set of screwdrivers (cross, flat, flat, T3, T5).
• 🧲 Screen suction cup.
• 🔥 Fryer (for softening glue).
• 🧴 Alcohol and plastic mediator.

⚠️ Warning: If you replace the connector yourself, you may be at risk of damaging the flexible plume or tearing the contacts off the motherboard.
