Xiaomi Mi8 is the flagship of 2018, which is still popular among users due to its powerful filling and high-quality sound. However, over time, the smartphone speakers get clogged with dust, villi or even moisture, which leads to distortion of sound, wheezing or complete disappearance of bass. If you notice that the sound has become quieter, there is cracking or distortion, the problem is most likely in the contamination of the speakers.
In this article, we will discuss 5 proven cleaning methods, from simple (using household products) to more complex (with partial disassembly). Mi8, It's a lot of damage, and it's also a lot of avoidable errors that make users break the speakers permanently (Mi8 SE, Mi9, POCO F1).
Signs of pollution speakers on Xiaomi Mi8
Before you start cleaning, make sure the problem is really in the speakers, not software failure or plume damage.

- π«οΈ Visible dirt β dust, villi or grains of sand under a protective net.
- π One speaker is working quieter than the other. Mi8 Two of them are the lower and the lower).
If the sound is lost completely or distorted even in headphones, the problem is most likely in the audio chip or firmware, in which case cleaning the speakers will not help, you will need a diagnosis in the service center.
β οΈ Warning: Do not confuse the contamination of the speakers with hardware damage to the membrane. If the sound became "bubbling" or completely disappeared after falling - it may be a rupture of the diffuser.

The choice of tools depends on the degree of contamination.
| Tool. | What's the point? | Limitations |

If you don't have compressed air on hand, you can use a cold-mode dryer (minimum power) and keep it at a distance of 15 cm and don't direct the airflow directly into the speaker -- just at an angle.
Method 1: Dry cleaning without disassembly (for mild contaminants)
This method is suitable if the Mi8 speakers are clogged with dust or villi, but there is no serious contamination. You do not need special tools, just what you have at home.
- Turn off your smartphone and get it out. SIM-card (just in case).
- Take a soft toothbrush (a new one is better) and walk gently across the speaker grid in circular motions. Don't press -- a light touch is enough.
- To remove large particles, use tape: stick the piece on the grid and sharply tear it off. Repeat 2-3 times.
- If you have any dust left, take a cotton swab and walk around the edges of the speaker. Don't put it deep!

Method 2: Compressed air purification (for deep dust)
If the dust has penetrated deep under the net, a regular brush will not help. Here you can use a compressed air balloon (sold in electronics stores or stationery stores).
Instructions:
- Keep the balloon vertically (do not tilt so as not to splash liquid).
- Point the tube at the speaker at an angle of 45 degrees, holding at a distance of 10-15 cm.
- With short presses (1-2 seconds) blow out the dust. Don't hold the button for long!
- Repeat for the second speaker (conversational).
β οΈ Warning: Never turn the balloon upside down, it will cause liquid air to be released, which can damage the membrane, and don't direct the jet directly into the speaker, which creates excessive pressure and the risk of rupturing the diffuser.
On the Xiaomi Mi8, the bottom speaker is particularly vulnerable because of the design: its mesh is thinner than that of the spoken speaker.
Method 3: Wet cleaning (for greasy spots and sticky dirt)
If the speaker has greasy spots (for example, from cream or cosmetics) or sticky dirt, dry cleaning will not help.
Step-by-step:
- Moisten the cotton swab with alcohol, then squeeze it so that it is barely wet.
- Gently wipe the edges of the speaker grid without touching the central part.
- To remove dirt from the crevices, use a toothpick wrapped with a wet napkin (not naked!).
- Let the smartphone dry for 10-15 minutes before turning on.
Don't use water or wet wipes - they leave a dent and can cause contact corrosion.The alcohol evaporates quickly and leaves no trace.

Method 4: Disassembly of the smartphone (for complex contaminants)
If the Mi8 speakers are heavily clogged (for example, after falling into the sand or prolonged use in a dusty room), a partial disassembly may be required. This method is risky β if you have never taken down a smartphone, you better contact the service.
What you need:
- π§ Set of screwdrivers (cross-haul) PH00, plastic mediator).
- π§² Screen removal suction cup (or credit card).
- π₯ Fryer (for softening glue).
- π§΄ Alcohol for cleaning contacts.
Step-by-step:
- Turn off your smartphone and take out the tray. SIM-map.
- Heat the screen edge dryer (not the display itself!) for 1-2 minutes to soften the glue.
- Push the screen with a plastic pickup (start at the bottom corner). Be careful, the plumes are thin!
- Unscrew 4 screws that fasten the metal plate over the speaker (they are under the screwdriver PH00).
- Carefully remove the speaker and clean it with a soft brush or compressed air. If necessary, wipe the contacts with alcohol.
- Collect the smartphone in reverse order, making sure that all the plumes are connected.
β οΈ Attention: On Xiaomi Mi8 The bottom speaker is soldered to the motherboard with thin wires, and if you rip them off, the sound will disappear completely!

Disassembling your smartphone is insecure (if it still works), and there is a risk of damaging the screen plume or disconnecting the battery.
Method 5: Software diagnostics (if the sound has not recovered)
If the speakers are still not working well after cleaning, the problem may be a software failure.
- Go to Settings β About Phone β The MIUI version and tap it 7 times to activate the developer mode.
- Go back to Settings β Additional β For developers and find the item Diagnostics of sound.
- Run a speaker test, and if one of them doesn't make sound, it's a hardware problem (damage to the plume or membrane).
- Reset to factory settings (Settings β Additional β Recovery and Reset) sometimes helps with software glitch.
If the test shows that the speakers are working, but the sound is still bad, try updating the firmware through Settings β System Update. Some versions of MIUI had sound bugs that were patched.
