Why are fingerprints so visible on Xiaomi smartphones?
Xiaomi smartphones β especially the Redmi Note, POCO X and Mi 11/12 series β are known for their glossy rear panels and oleophobic glass screens. It is this coating, despite its scratch-proofing, that becomes a magnet for greasy footprints. The oleophobic layer wears out over time, and the factory coating on budget models (such as the Redmi 9A or POCO M3) is initially thinner than that of flagships.
Also, the chemistry of sebum is unique in each person: some have almost invisible traces, others turn into sticky stains after 5 minutes of use. Add dust that sticks to the greasy surface, and you get the effect of a dirty screen even on a new phone.
Itβs important to understand that the problem isnβt Xiaomiβs βbad qualityβ but the physical properties of the materials. For example, matte rear panels (like the POCO X3 Pro) collect fewer prints, but are harder to clean because of the microtexture. And glossy surfaces (like the Mi 11 Ultra) shine so that even microscopic traces become visible at a certain angle.
Quick ways to remove fresh prints (without special means)
If the footprints are recent and have not mixed with the dust, they can be removed by improvised means, the main rule is: do not use abrasive materials (paper wipes, towels, clothing) that scratch the oleophobic coating, making the screen even more vulnerable to contamination.
- π§» Microfiber wipe (complete with glasses or photo equipment) Movements should be circular, without pressing. For best effect, slightly moisten the napkin with water and squeeze.
- π Cotton T-shirt. It's only suitable for the back, you can scratch the screen with seams. Use a smooth piece of fabric without embroidered logos.
- π§ Distilled water + Moisten the disc with water (don't drip directly on the phone!), wipe the surface, then dry with microfiber. The method is safe even for charging ports.
- πΊ A weak beer solution (3-5%). The ethyl alcohol in the beer dissolves the fat. Apply the drop on a napkin, wipe the screen, then remove the residues with a dry microfiber.
β οΈ Warning: Never use vinegar, lemon juice or household chemicals (such as window cleaners) to clean the oleophobic coating, and aggressive surfactants leave stains that are difficult to remove.
For owners of Xiaomi with AMOLED-screens (e.g., Mi) 10T Pro or Redmi K40) It is important to avoid excess moisture. Getting water in the speakers or under the frame can cause green stripes on the display due to corrosion of the contacts.
Professional means for removing persistent traces
If the prints have been ingested or mixed with dust, you need specialized formulations, you can buy them from electronics stores or order them online, and you can choose a product without acetone, ammonia and abrasive particles.
| Remedy. | Suitable for | Pluses | Cons |
|---|---|---|---|
| Zeiss wipes for optics | Screens, cameras, glass panels | Do not leave divorces, are safe for oleophobic coating | Dear (from 500) β½ For packaging, quickly consumed |
| Whoosh spray! Screen Shine | All types of screens, including AMOLED | Kills bacteria, restores the oleophobic layer | Requires the purchase of microfiber wipes separately |
| Klear Screen liquid | Glossy and matte surfaces | Economical (enough for 100+ cleanings), without alcohol | It dries for a long time (you need to wipe 2 times). |
| Invisible Glass gel | Highly contaminated screens | Removes even old traces of creams | May leave stickiness when applied incorrectly |
For models with matte glass (for example, POCO F3 GT or Redmi Note 10 Pro) it is better to choose products marked "for matte surfaces". Conventional alcohol sprays can leave white spots due to the texture.

How to Restore Oleophobic Coverage on Your Own
If the prints appear within minutes of cleaning, the oleophobic layer on the Xiaomi screen is worn out and can be restored at home with special formulations, such as:
- π§΄ Phobik (from the Spigen brand) is a gel that is distributed by microfiber. It lasts up to 1 year.
Critically, before applying the new coating, the screen should be perfectly clean, and the residue of grease or dust will lead to uneven distribution of the composition and the appearance of divorces.
Recovery process:
- Clean the screen with isopropyl alcohol (90%+) for degreasing.
- Apply the product to a microfiber wipe (not on the screen!).
- Rain circular movements for 1-2 minutes before the formation of a uniform film.
- Do not turn on the phone for 12-24 hours (the polymerization time is indicated in the instructions).
β οΈ Warning: Do not use silicone sprays or car polishes to repair the oleophobic layer, which create a sticky film that attracts dust and worsens the tactile sensation when touched.

How to Prevent Fingerprints: Prevention
The best way to deal with fingerprints is to keep them out of the picture. Here are some proven methods:
- π± Use an oleophobic glass film (like Spigen's Tempered Glass or Nillkin's) that not only protects against scratches, but also reduces fat adhesion.
For owners of Xiaomi with AMOLED-displays (e.g. Mi 11 Lite or POCO F4) It is useful to disable the function Always on Display (AOD). Constantly burning pixels attract dust that mixes with fat from the fingers.
π‘
If you use your phone outdoors often, carry a compressed air mini canister (for example, to clean the cameras) with you. One short breath is enough to remove dust from the screen before wiping - this will prevent scratches.
What to do if the prints are under film or glass?
If the traces appear under the protective film, it means that it is not properly pasted or has lost its adhesive properties.
- Carefully tuck the film with a plastic card or mediator.
- Remove it and clean the screen with isopropyl alcohol.
- Stick a new film, squeezing air from the center to the edges, and use a microfiber-wrapped bank card to do that.
For tempered glass (e.g. Tempered Glass), the problem is usually a poor-quality adhesive layer. Cheap glass (costs up to 300). β½) They often turn yellow and collect dirt underneath. UV-glue (for example, Whitestone Dome), which polymerizes under ultraviolet light and does not leave bubbles.
If there's dust under the glass, and you can't replace it, use a vacuum cleaner with a narrow nozzle at minimum power. Put a nozzle to the edge of the glass and carefully pull out the particles. Don't press too hard, it can tear the glass.
Myths about fingerprint removal that ruin your Xiaomi
There are dozens of "popular" screen cleaning tips on the Internet, most of which are not just useless, but dangerous.
- π§Ό "Toothpaste wipes off traces" β The abrasive particles in the paste scratch the screen, making it cloudy. It's irreversible!
- π "Lemon juice disinfects and cleanses" β The acid erodes the oleophobic coating and can penetrate under the frame, causing corrosion.
- π§΄ "Wet wipes for hands will do" β They contain aggressive surfactants that leave a sticky plaque.
- π₯ "Heating a hair dryer will remove fat" β Overheating can damage OLED-matrix (on Xiaomi with AMOLED-screen).
It's especially dangerous to follow the advice of "wipe the screen with gasoline" or "use an eraser." Gasoline dissolves the plastic elements of the case, and eraser erases the oleophobic coating, after which the traces will appear even faster.

If you are in doubt about the cleaning method, ask yourself the question: "Would this method be safe for anti-reflective glasses?" If not, do not use it for your smartphone.
