The protective glass on Xiaomi is not just an accessory, but a necessary measure to keep the screen from scratches, chips and cracks. Even the most durable AMOLED or IPS displays in Redmi, POCO or Xiaomi 13/14 smartphones are vulnerable to falls and mechanical damage. However, many users face problems when gluing: bubbles, dust under glass, improper positioning. In this article, we will analyze the step-by-step process, reveal the secrets of professionals and tell you how to avoid typical errors.
The feature of Xiaomi smartphones is their design with curved edges of the screen (the Mi 11 Ultra models, 12S Ultra or front camera cutouts (dot-drop, punch-hole) that make it difficult to install the glass, but with our tips you can even cope with the problem. 3D-And if you've never glued glass yourself, don't worry, our guide is suitable for beginners and experienced users alike.
1.Selection of protective glass: which is suitable for your Xiaomi
The first step is to choose the right accessory. Not all glasses are equally useful: cheap ones can not only protect poorly, but also reduce the sensitivity of the screen.
- 📱 Smartphone model: Glass should be designed specifically for your model (e.g. Redmi Note 12 Pro)+ and POCO F5 They have different notches for the speaker and the camera. Universal glass rarely fits perfectly.
- 🛡️ Thickness and strength: Optimal thickness - 0.2-0.33 mm Too thin glasses (less than 0.15 mm) easily scratched, and thick (more than 0.5 mm) can interfere with the operation of the case.
- 💧 Type of adhesive layer: Silicon-based, easy to reglue, but worse to hold. Full-glue, more reliable, but harder to install.
For flagships Xiaomi (series 13/14, Mix Fold) recommend glass with oleophobic coating — it repels greasy fingerprints. and for budget models (Redmi A2, POCO M5) suitable glass with 2.5D-cut — they are cheaper and easier to install.
⚠️ Note: Do not buy glass with an inscription «9H» — This is a marketing ploy. The real Mohs hardness of the best glass is 6–7H, «9H» It means only resistance to scratches, not to impacts.
| Type of glass | Suitable for models | Pluses | Cons |
|---|---|---|---|
| 2.5D (flat) | Redmi 10/12, POCO X3/X5 | Easy installation, low price | Doesn't cover the edges of the screen. |
| 3D (curved) | Xiaomi 13/14, Mix 4 | Full display coverage | Hard to glue, more expensive. |
| Full-glue (full-glue) | All flat-screen models | Maximum protection, no bubbles | Difficult to reglue when mistaken |
| Hybrid (glass + film) | Xiaomi Civi, POCO F4 | Subtle, does not impair sensitivity | Less strength |
2.Preparation of the smartphone: what to do before sticking
Preparation is 90 percent of the time, and even the most expensive glass will look terrible if it's left with dust or grease.
- Turn off your smartphone – this will help you avoid accidental touches and see the dust on the screen.
- Remove old glass or film. If it's cracked, use a scotch or plastic card to poke the edge. Don't use a knife or metal objects!
- Clean the screen with a special microfiber wipe (comes with glass). To remove fat, use isopropyl alcohol (70%+) or a special cleaner.
Pay special attention to the edges of the screen and the notch under the camera, which accumulates the most dirt. For hard-to-reach places, use a cotton swab dipped in alcohol. Check the screen under bright light: if you see any swelling or dust, repeat the cleaning.

⚠️ Warning: Do not use household alcohol or cologne to clean, they leave a greasy film. Also avoid paper wipes: they scratch the screen with microparticles.
If you stick glass on a new smartphone (for example, just unpacked Xiaomi 14), still clean – the factory screen is covered with a protective transport film, which leaves a sticky trace.
3. Step-by-step instruction: how to glue glass without bubbles
Now, to the most critical stage, you'll need glass, a napkin, a positioning frame (if any), a bubble-extracting card (or a bank card).
- Unpack the glass in a clean room (better in the bathroom after the shower - there is less dust there), remove only the top protective film (the one with the logo).
- Line the glass across the screen. If you have a frame, put it on your smartphone, then put it inside. If you don't have a frame, gently apply the glass to the top of the screen and slowly lower it.
- Stick the glass on: 👆 Raise the glass at one end by 1-2 cm. 🧼 Remove the lower protective film (it is sticky!). 📲 Instantly lower the glass on the screen, starting at the top.
Remove the bubbles.
If you have small bubbles, don't panic. Most of them will disappear on their own in 12 to 24 hours. Large bubbles (more than 2 mm) mean that dust has fallen under the glass - you have to glue it.
What to do if the glass is crooked?
💡
If you have a Xiaomi with a curved screen (like the Mi 11 Ultra), use liquid glue for the edges. Apply it with a brush from the kit before installing the glass - this will improve clutch on the rounds.
4.Typical mistakes and how to avoid them
Even experienced users sometimes make mistakes. TOP-5 problems and solutions:
- 🌀 Bubbles around the edges: They arise from dust or improper air extrusion. The solution is to use a positioning frame and clean the screen in two directions (top down and right to left).
- 🖼️ The glass does not stick to the edges: Typical for 3D-The solution is to heat the edges with a hairdryer at a minimum power (no more than 30 seconds) or use liquid glue.
- 👆 Elevated corners: The glass is too big or the screen is not cleaned enough.The solution is to cut the excess with a stationery knife (only for the purpose of the slasher). 2.5D-glass! or re-glaze.
- 📵 Poor screen sensitivity: Too thick glass or poor-quality glue, the solution is to choose glass with an oleophobic coating of 0.2-0.3 mm thickness.
- 💥 Cracks when glued: Glass of poor quality or too much pressure, the solution is to buy glass with a tempered layer and not press the screen when installed.
A particular problem is that the glass is broken off after a week, and it's because of:
- Cheap glue (it dries up with time).
- Frequent use of the smartphone in wet conditions (for example, in the bathroom).
- Using alcohol-containing wipes to clean over glass (they dissolve glue).
💡
If the glass starts flaking off at the edges, don't try to glue it with superglue or tape! this will ruin the screen. Better buy new glass with an improved adhesive layer (like the Spigen or AmFilm brands).
5. Features of sticking on different models Xiaomi
The design of the screen in different Xiaomi lines varies, so the approach to installing glass is different.
| Xiaomi model | Screen type | Recommended glass | Features of installation |
|---|---|---|---|
| Redmi Note 10/11/12 | Flat AMOLED, 2.5D-edged | 2.5D or 3D (with a cutout under the camera) | Easy to glue, but check compatibility with the case - some glass thickens the screen. |
| POCO F3/F4/F5 | Flat AMOLED, 120Hz | Full-glue or hybrid | Due to the high refresh rate, glass with poor oleophobic coating is quickly covered by divorces. |
| Xiaomi 13/14 Pro | curved AMOLED, 3D-edge | Only 3D-liquid-glue | It requires a hairdryer to warm up the edges. Don't use it. 2.5D-The glass doesn't cover the entire screen. |
| Xiaomi Mix Fold 2/3 | Foldable AMOLED | Special flexible glass | Installation only in the service center! Self-sticker can damage the loop. |
| Redmi A1/A2 | Flat IPS, budget-friendly | 2.5D or film | The screen is poorly protected from scratches – glass is a must, even if the phone is cheap. |
For Xiaomi with a subscreen camera (like the Mi Mix 4), choose glass with a transparent area above the camera. If you stick conventional glass, the sensitivity of the sensor will drop by 30-40%.
⚠️ Note: Xiaomi Black Shark (gaming smartphones) is not recommended to glue glass thicker than 0.25 mm - they worsen the work of tactile triggers (virtual buttons on the screen).
6. Care for the protective glass: how to extend its service life
Even a perfectly pasted glass won't last long if it's not properly cared for.
- 🧴 Cleanup: Use only microfiber and distilled water. Alcohol wipes corrode oleophobic coating.
- 📦 Storage: Do not put your smartphone down on hard surfaces (table, keys). 9H-glass is scratched by sand or metal.
- 💦 Humidity: Avoid water under glass. If your smartphone gets wet, dry it with silica gel.
- 🔄 Replace: Change the glass every 6-12 months – over time, the glue loses its properties and the coating is erased.
If you have microcracks on your glass, don't delay replacing it, and it's not only bad for your appearance, it's bad for you.
- Bacteria are collected (mud accumulates in cracks).
- The fingers are sliding (the edges of the cracks) are getting worse.
- They can cause the crack to spread to the screen itself on impact.
💡
To check if the glass has lost its protective properties, swipe it with a metal key (easy, without pressing).
7. Safety glass alternatives: when it is not suitable
Glass is not a good choice in some cases, so let's look at the alternatives.
- 📄 Protective film: Suitable for Xiaomi with curved screen if you can’t find it 3D-Modern film (like Skinomi) self-repair from scratches.
- 🛡️ Liquid glass: Apply as a coating and fill microcracks, lasts 6-12 months, but does not protect against shocks.
- 📱 Case with projections: If you do not want to glue the glass, choose cases with a height above the screen (for example, Spigen Tough Armor), which will prevent the screen from contacting the surface when falling.
For Xiaomi with a subscreen fingerprint scanner (such as the Xiaomi 13T), glass thicker than 0.3 mm can degrade the sensor, in which case it is better to use thin film or liquid glass.
⚠️ Warning: Some smart films (such as those with anti-reflective effects) reduce screen brightness by 15-20.
