Owners of modern smartphones Xiaomi, Redmi and Poco know that the screen is the most vulnerable part of the device. Despite the use of durable glass Gorilla Glass latest versions, accidental fall on the pavement or contact with keys in your pocket often lead to cracks and chips. Replacing the display in an authorized service can cost up to 40-50% of the price of the gadget, making self-installing protection economically viable solution.
The process of sticking seems simple only at first glance, but requires a certain skill and purity. In this article, we will discuss all the nuances of preparing the work area, choosing quality accessories and step-by-step algorithm of actions that will avoid bubbles and detachments. You will learn why full-glue glass is preferable for curved screens of the Mi and Note series, and how to properly prepare the surface for perfect grip.
Before you start taking action, you need to make sure that you have all the necessary tools at hand and the accessory is selected correctly. You should not skimp on the protective layer, since cheap counterparts often have low-quality oleophobic coatings that wear out in a couple of weeks, leaving the screen sticky and dull. A quality installation will prolong the life of your device and preserve its commercial appearance when resold.
Choosing a high-quality protective glass for Xiaomi
The accessories market is crowded with offers, and choosing a truly reliable product among thousands of options can be difficult. For Xiaomi smartphones, it is critical to consider the shape of the display, since many models have 2.5D or even 3D curved edges. Conventional flat glass may not stick around the perimeter, creating so-called “rainbow” or white stripes that spoil the visual perception and reduce the sensitivity of the touchscreen.
Pay attention to the hardness marking, which is usually 9H. This indicator means resistance to scratches from metal objects, but does not guarantee protection from falls. The more important parameter is the manufacturing technology: tempered glass undergoes special heat treatment, which increases its viscosity. It is also worth checking for an oleophobic coating that repels greasy fingerprints and facilitates slipping.
- 📱 Type of coverage: choose matte glass for gamers (less glare) or transparent for fans of bright photos.
- 🛡️ Thickness: the optimal range is from 0.26 mm to 0.33 mm, so as not to increase the weight of the device.
- 📐 Shape: For models with curved edges (for example, Mi 11, Xiaomi 13 Pro) take 3D or 5D black-framed.
Special attention should be paid to UV-adhesive glass, which is a liquid polymer that hardens when exposed to ultraviolet light, ideal for flagships with highly curved displays, because the glue fills all the microslobs and provides 100% fit, but the process of installing such solutions is more complex and requires more care not to pour glue into the speaker or buttons.
Tools and workplace preparation required
The success of the operation depends on preparation, 90%, and the dust and villi are the main enemies of the sticker, because even a microscopic particle under the glass will create a visible air pocket that will be difficult to get rid of later on, you'll need a perfectly clean surface, good lighting and no drafts that can lift dust from the floor.
A standard set is usually complete with quality glass, but it is better to check in advance for it. If something is missing, it is easy to find in the hardware store or among household trifles. The main thing is not to use piled fabrics such as cotton cotton wheels or paper napkins, as they leave a micro-volt.
- 💧 Degreasing: alcohol wipe or glass cleaning liquid (isopropyl alcohol).
- 🌬️ Scotch: ordinary transparent or special sticky layer for dust removal.
- 🧻 Microfiber: Lickless fabric for polishing the screen before final gluing.
Prepare the table, wipe it with a damp cloth and let it dry. This will prevent dust from rising while working. It is also recommended to wash your hands with soap to degrease your fingers, which will touch the edges of the glass and the smartphone screen. Static electricity can play a cruel joke by attracting dust, so try to minimize the friction of clothes on the table.
⚠️ Warning: Never use ammonia window cleaners or acetone to clean the screen, which can damage the oleophobic layer of the display itself and dissolve the adhesive base of the protective glass.
Step-by-step: how to glue glass without bubbles
The most critical step is to be cool and precise, take your time, each step must be done sequentially, first wipe the screen thoroughly with an alcohol wipe, removing all greasy spots and contaminants, then walk through a dry microfiber, polishing the surface to a perfect shine.
Use a sticky layer (scotch) to clean the final cleaning, walk it all over the screen, collecting dust particles that are invisible to the eye, and then you can remove the protective film from the glass itself. Try not to touch the sticky side with your fingers, holding the glass by the ends.
☑️ Checklist before gluing
Carefully apply the glass to the screen, focusing on the speaker and the edges of the display. Most modern glasses for Xiaomi have a silicone adhesive layer that allows you to adjust the position slightly until the moment of full pressing. After making sure that all the holes are matched and the indentations are symmetrical, smoothly lower the glass and swipe the finger from the center to the edges, expelling air.
If you have small bubbles, don't panic. They often disappear by themselves. 24-48 You can use the time frame to push the bubble through a microfiber and lead it to the nearest edge, and you can try to move large air pockets with a plastic card wrapped in a fabric.
💡
If you're gluing glass for the first time, leave one narrow strip of protective film on the adhesive side of the glass. Stick this loose part to the edge of the screen, align the glass, and then completely remove the film and press the accessory.
Features of installation on a model with a curved screen
Xiaomi's flagship models often feature curved edge displays (2.5D and 3D). The usual flat-paneled glass on these screens is held only in the center, leaving an air cushion on the sides. This not only looks unaesthetic, but also causes the glass to unstick at the slightest touch of the edge, the solution being special 3D/5D glass or hydrogel films.
When installing 3D glass, it is important to correctly combine the black frame of the accessory with the boundaries of the display. The slightest skew will lead to the fact that on one side the glass will hang over, and on the other – will not cover the usable area. In some cases, if the glass has a rigid frame, you may need to use a case that will not press on the edges, otherwise you will have rainbow glare.
For highly curved screens, such as the Mi 11 Curved or Xiaomi 12 Pro, UV-adhesive glass is best suited. The technology involves applying a liquid polymer to the screen, then applying glass on top. Under the action of an ultraviolet lamp, the glue solidifies, creating a monolithic design, which provides better shock protection and the perfect work of the fingerprint scanner built into the screen.
| Screen type | Recommended protection | Complexity of installation | Compatibility with covers |
|---|---|---|---|
| Flat (Flat) | 2.5D glass | Low. | Tall. |
| 2.5D (rounded edges) | 3D/5D glass with black frame | Medium | Medium |
| 3D (strong bend) | UV-glass | Tall. | Depends on the case. |
| Screen with scanner in display | Thin glass (< 0.3 mm) or UV | Medium | Tall. |
MIUI or HyperOS settings often have an option to "Enhance Screen Sensitivity" or "Security Glass Mode" that needs to be activated, and it is also recommended to re-geoin your fingerprints after you install protection.
Removing common problems and defects
Even experienced craftsmen sometimes fail, and the most common problem is getting dust under the glass. If you notice a speck of dust immediately after the sticker, don't try to squeeze it out to the edge, because you're just scratching the adhesive layer or the screen, in which case you need to gently lift the glass from one edge using a thin needle or tape, and repeat the cleaning procedure with a sticky layer.
Another problem is that you don't fit the edges completely, and this often happens if the screen is grease-contaminated, or if the glass is not compatible with the shape of the body, and in the case of fat, you can try to warm the edges with a hairdryer (not too hot air) and press it hard, and if the glass doesn't fit geometry, unfortunately, it will only help if you replace the accessory with a better version of the Full Glue label.
- 🌈 Rainbow effect: occurs due to the pressure of the cover on the edges of the glass, the solution is to replace the case with a looser one or cut the edge of the glass (not recommended).
- 💨 Air bubbles: small ones will disappear on their own, large ones can be pushed to the edge through microfiber.
- 📉 Bad Touch: Check if the glass is too thick and turn on the hypersensitivity mode in the settings.
⚠️ Warning: If a large villi or hair is hit by a glass and you decide to remove the glass for cleaning, do so extremely carefully. Reusing the adhesive layer of ordinary glass often leads to stripes and deterioration of transparency.

Protective care and service life
Properly installed, quality glass lasts 6 to 12 months, retaining its protective and tactile properties. However, over time, the oleophobic coating becomes thinner and the screen becomes less pleasant to the touch. To extend the life of the accessory, wipe it with a soft microfiber, avoiding the use of aggressive chemistry.
Check the edges of the glass regularly. If you notice that it has started to break off or cracked, it is better to replace it immediately. The crack can spread further, and the sharp edges of the chipped glass can scratch the finger or the screen of the smartphone on the next impact.
Don’t carry your smartphone in your pocket with your keys or small change, even if it’s covered with glass.Abrasive exposure to sand or metal can leave micro scratches on the protective layer itself, which will become noticeable over time when the screen is turned off.Using a case with raised edges will also significantly reduce the risk of damage when falling.
💡
The quality of the installation depends on the cleanliness of the room and the preparation of the surface: 90% of the success is the removal of dust before removing the protective film.
