How to clean the speaker on Xiaomi Redmi Note 8T: safe methods and life hacks

Why is the speaker on Xiaomi Redmi Note 8T starting to wheez or quieter?

The speaker of your Redmi Note 8T can lose clarity over time, with wheezing, distortion or a noticeable decrease in volume. 90% of the time, the cause is not a hardware breakdown, but a banal clogging with dust, villi or toxin deposits, and a particularly pressing problem for users who often carry their phone in their pocket or bag without a cover.

The design of the speaker in this model involves microscopic holes for the output of sound, which are clogged with debris. Unlike the main speaker (located on the lower end), the speaker is located next to the front camera and is not protected by the grid, which makes it more vulnerable. Before you carry the phone to the service center, try to clean it yourself.

Signs of a clogged speaker: when is it time to clean?

The volume reduction is not always due to pollution, so to avoid wasting time, check these symptoms:

• 🔊 The sound becomes muffled, as if from under a blanket (especially noticeable when talking on the phone).
• 🎵 Extraneous noises appear: cracking, hissing or gurgling when reproducing the voice of the interlocutor.
• 📞 In hands-free mode, the sound remains clear, and in a normal conversation – distorted.
• 🌫️ Visible dust or dirt particles around speaker holes (can be viewed with a flashlight).

If at least 2-3 points match, the problem is almost certainly clogging. But before cleaning, eliminate software reasons: check the volume settings in Settings → Sound and make sure that the Do Not Disturb or Quiet Mode mode is not activated.

Method 1: Compressed air cleaning (the safest way)

Using compressed air spray (sold in electronics stores or household goods) is the best option for beginners, a method that does not require disassembling the phone and minimizes the risk of damage.

You'll need:

• 💨 Compressed air canister (for example, Kontakt Chemistry or Office Depot).
• 🔦 Lantern (for lighting the speaker holes).
• 🧴 Cotton swab (in case you need to clean up).

Step-by-step:

1. Turn off your phone to avoid accidentally pressing buttons.
2. Hold the sprayer vertically 3-5 cm from the speaker. Never tilt the balloon - this can cause the liquid to eject!
3. With short presses (for 1-2 seconds), blow the speaker holes. Repeat 3-4 times.
4. Wait 5 minutes for the condensate (if it appears) to evaporate.
5. Check the sound by calling another phone.

Turn off the phone.

Close the microphone with your finger (to prevent debris from getting inside)

Hold the cylinder strictly vertically

Blow with short presses (no more than 2 seconds)

Let the phone dry 5-10 minute-->

⚠️ Warning: Do not use a home hair dryer or vacuum! airflow from these devices is too strong and can damage the speaker membrane or drive dust deeper.

Method 2: Cleaning with a soft brush or cotton swab

If you don't have compressed air at hand, you can use the tools at hand, and the main rule is not to use sharp or hard objects (toothpicks, needles, paper clips) that can scratch the mesh or membrane.

The best tools for manual cleaning:

• 🖌️ Soft art brush (size) 0-2).
• 🧼 Cotton swab, slightly moistened with alcohol (no more than 70%!).
• 🧴 Toothbrush with soft bristles (new, unused).

Cleaning technique:

1. Carefully sweep the speaker with a brush or cotton swab along the holes parallel to the screen (without pressing!).
2. To remove sticky deposits (for example, from cream or sweat), use a stick dipped in isopropyl alcohol.
3. Don’t apply force – the speaker is attached to the glue, and excessive pressure can displace it.

💡

If there is no alcohol at hand, you can use a wet napkin for glasses - it leaves no villi and is safe for electronics.

Method 3: Ultrasonic cleaning (for advanced users)

This method is suitable if the speaker is clogged deep inside (for example, after ingress of liquid or prolonged use in dusty conditions).

What will be required:

• 🛁 Ultrasonic bath (you can buy an inexpensive model for jewelry).
• 💧 Distilled water or special liquid for ultrasonic cleaning.
• ⚙️ Screwdriver for disassembling the phone (if you decide to remove the speaker).

Important: This method requires a partial disassembly of the phone, and if you've never disassembled a smartphone, you should go to the service. For the Redmi Note 8T, the procedure is:

1. Plug off the back cover (use a plastic shoulder blade and hair dryer to soften the glue).
2. Disconnect the battery plume to avoid short circuit.
3. Remove the metal plate covering the speaker (it is attached to 2-3 screws).
4. Place the speaker in an ultrasonic bath for 1-2 minutes at a temperature of 30-40°C.
5. Dry the speaker for 24 hours in a dry place (silicagel can be used).

⚠️ Warning: Don't put the entire phone in an ultrasonic bath - it will cause irreversible breakdown.

Method 4: Software Diagnostics Before Cleaning

Before you start a physical cleanup, make sure the problem isn't with the settings or the software.The Redmi Note 8T has built-in tests to check the speaker.

How to start the diagnosis:

1. Open the Phone app and dial ##4636##.
2. In the menu that opens, select Phone Information.
3. Scroll down and press the speaker check.
4. If the sound in the test is clear, and when talking - not, the problem is precisely the clogging.

Also check:

• 🔇 Is the "Silent Sound" mode activated in Settings → Special facilities → Rumor.
• 🔊 Is there a volume limit in the settings? → Sound. → Safe volume.
• 📱 Are third-party applications affected (e.g., sound managers or uniform equalizers).

💡

If the speaker works perfectly in test mode, and when talking the sound is distorted, the problem is in the microphone or network settings, not in the dynamics.

Method 5: Professional cleaning in the service (when nothing helps)

If the independent attempts failed, it is possible that the speaker is damaged or clogged at the chip level. In this case, it is better to contact the service center. For Xiaomi Redmi Note 8T, the average cost of services:

When choosing a service, pay attention to:

• 🛠️ Original spare parts (Dynamic for Redmi Note) 8T articulate MDY-11-13).
• 📄 Work guarantee (minimum 3 months).
• 👨‍🔧 Reviews about the master - cleaning the speaker requires accuracy.

Should you repair or replace your phone? If other components (battery, screen, camera) are in good condition, repair is warranted.The Redmi Note 8T is still a relevant model thanks to balanced specs and support for updates.

Prevention: how to prevent the clogging of the speaker?

To avoid having to clean the speaker every few months, follow the simple rules:

• 📱 Use a cover with screen protection - it reduces the entry of dust into the speaker holes.
• 🧴 Regularly wipe the area around the speaker with a dry wipe made of microfiber.
• 🚿 Avoid using your phone in dusty spaces (such as construction sites) or in the rain.
• 🔊 Do not turn on the maximum volume for a long time - this can lead to overheating and deformation of the membrane.
• 🔄 Once every 3 months, blow the speaker with compressed air (even if there are no visible problems).

If you talk on your phone frequently in high humidity (such as in the gym), wipe the speaker with a dry wipe after use, which will prevent contact oxidation and the formation of sticky plaque.

💡

Keep your phone in your pocket with a screen to your body, so the speaker has less contact with the fabric of clothing that can cling to the holes.
