The security glass on Xiaomi's screen is not a luxury, it's a necessity. Even the most durable displays of Redmi, POCO or Mi are not immune to scratches, chips and cracks when falling. But many users face the problem: how to stick it flat, without bubbles and dust? In this article, we will analyze the step-by-step instructions with video, reveal the secrets of professional installation and warn against the typical mistakes that spoil 90% of self-attempts.
You think it's enough to just put glass on the screen? In practice, it's more complicated: it's about surface preparation, the right tools and even the humidity in the room. We've tested the methods on Xiaomi 14 Ultra, Redmi Note 13 Pro+ and POCO F6 models, and we're ready to share the working circuits. And at the end of this article, you'll find a list of proven video instructions from the masters who glue the glass daily.
Why is the security glass on Xiaomi a must-have?
Gorilla Glass Victus 2, which is equipped with flagship Xiaomi, is really stronger than previous generations, but it will not save from:
- 🔪 Microcracks from sand or metal objects in your pocket (keys, coins).
- 💥 Broken screen when falling on asphalt - even from a height of 50 cm.
- 📱 Loss of touchscreen sensitivity due to scratches (relevant to the AMOLED-display).
- 💰 Expensive repair: replacing glass with Xiaomi 13T Pro costs 15-25 thousand rubles.
And glass also retains a tactile sensation, unlike the film that blurs the screen, but only if it's glued correctly, or you get blurry text, rainbow swellings and bubbles that drive you crazy.
What kind of security glass to choose for Xiaomi: comparison of types
Not all glasses are the same. Xiaomi has 3 main types, and each has pros and cons:
| Type of glass | Pluses | Cons | Suitable for models |
|---|---|---|---|
| 2.5D (flat) | Easy installation, low price (200-500) ₽), fitting | Does not close the rounded edges of the screen, visible "step" at the edges | Redmi Note 12/13, POCO X5, Mi 11 Lite |
| 3D/Full Cover | Full screen coverage, including edges, unnoticed on the phone | Difficult to glue, expensive (800-1500) ₽), may conflict with covers | Xiaomi 13/14, Mix Fold 3, Black Shark 5 |
| Liquid glass (nano-coating) | Invisible, not felt on screen, self-regenerates with small scratches | Does not protect against blows, is difficult to apply, lasts 6-12 months | Any model, but better for AMOLED-display |
Important for Xiaomi with curved screens (like Xiaomi 13 Ultra or Mix Fold): standard 2.5D-You need to look for options that are labeled "Full Glue" or «3D Curved».
If in doubt, take a kit with tools (wipes, vacuum cleaner, positioner). For example, kits from Spigen or AmFilm include everything you need and guarantee a perfect fit.
Preparation for installation: what will be needed?
Before you put the glass on, prepare the workspace and tools.
- 🧹 Clean room without dust (better after wet cleaning).
- 💡 Bright lighting to see the smallest sores.
- 🕒 Time: Take your time, installation will take 20–40 minutes.
- 📱 Charged phone (in case you need to regurgitate).
Tool list:
Ultraviolet lamp (for glass with UV-glue)|Wipes made of microfiber (2-3 pcs.)|Scotch for dust removal|Positioning device (device for flat installation)|Alcohol wipes (70% isopropyl alcohol)|Plastic card or mediator for smoothing|Vacuum cleaner or sticky roller (for 3D-glass-glass)-->
If you have Xiaomi with an oleophobic coating (such as Mi 11 or newer), do not use aggressive solvents - they will damage the factory layer.
💡
Before you install, turn off the phone or put it in flight mode, and the vibration from the notifications can move the glass during the pasting process.
Step-by-step: how to glue glass on Xiaomi without bubbles
Follow this algorithm and you will get the perfect setup the first time:
- Screen cleaning. Remove old glass or film (if any). Wipe the screen with an alcohol solution (70% isopropyl alcohol + 30% distilled water), then with a dry microfibre wipe. Movement from center to edges. How to remove glue residues? Use a wooden stick or plastic card to scrub glue neatly. Then wipe the screen with alcohol. Don't use metal objects!
- Dust removal. Turn on the flashlight on the other phone and light it up at an angle -- you can see even microparticles. Remove them with dust tape or sticky roller. Repeat 2-3 times.
- Test landing. Put the glass on the screen without removing the protective film and check if the cutouts match the speaker and the camera. If the glass is walking, use the positioner.
- Stick. Take the bottom protective film off the glass and gently apply it to the screen, starting at the top. Don't press! Let the glass lie down under its own weight. 3D-glass: first glue the top, then warm the edges with a hairdryer (at minimum power) and press with a plastic card.
- Final treatment: Smooth the glass from center to edge with a plastic card. If there are bubbles left, gently tuck the glass in and remove the air (only in the first 5 minutes!).
For UV-adhesive glass (e.g. Xiaomi Mix Fold): After installation, light the screen with a UV lamp for 20–30 seconds to polymerize the adhesive.
💡
The key point is, if the glass is crooked, you have 1-2 minutes to fix it carefully, and then the glue is grabbed, and you have to re-glue it.
Common Mistakes and How to Avoid Them
Even experienced users make these mistakes, and here's how to prevent them:
⚠️ Warning: Never put a glass on a hot screen (for example, after a game) the glue will grab too fast and the bubbles will be impossible to remove.
- 🌀 Bubbles around the edges. It's dust or uneven pressure. Solution: use a positioner and smooth the glass from the center.
- 📏 The glass went crooked, cause: hasty or incorrect test landing. Solution: Before you stick it, mark the center of the screen and the glass with a marker.
- 🧴 Rainbow divorces. The reason is cheap glue or leftover fat on the screen. Solution: Clean the screen with alcohol only, without soap or household chemicals.
- 🔍 Dust under glass. Reason: not enough cleaning. Solution: put it in the bathroom after a hot shower (the steam precipitates the dust).
If the glass does fall out, don't panic. You can reglaze it, but you'll need to:
- Heat the glass with a hair dryer (to soften the glue).
- Carefully tap him with a guitar mediator.
- Clean the screen with alcohol and repeat the process.

What to do after installation?
You put a glass on, but that's not all, so it lasts a long time.
- ⏳ Do not use the phone for 1-2 hours – let the glue dry completely.
- 📵 Avoid covers for the first day (they can move the glass).
- 🧼 Do not wash the screen with soap or aggressive agents for 3-5 days.
- 🔍 Check the sensitivity of the touchscreen - if there are lags, glue the glass.
How to check the quality of the installation?
- Light the flashlight at an angle - there should be no bubbles or rainbow spots.
- Swipe your finger around the edges - the glass should not "cling" to the cover.
- Run a touchscreen test (such as the Touch Screen Test app).
⚠️ Warning: If bubbles appear under the glass after 2-3 days, do not try to squeeze them out! This means that the dust has fallen under the glue, and the glass must be glued back.
