How to put a protective glass on a Xiaomi smartphone: full instructions

Modern smartphones of the Xiaomi brand are equipped with high-quality screens, but even the durable glass Gorilla Glass does not give a hundred percent guarantee of protection from falls or scratches with keys in your pocket. A crack on the display is the most common reason for contacting service centers, and its replacement cost can reach 70% of the price of the device, which is why installing an additional protective layer is the first action to be performed immediately after buying a gadget.

Many users are afraid to do the gluing themselves, believing that at home you can not achieve the perfect result without air bubbles and dust. However, if you look ahead to how to put the protective glass on Xiaomi video, and prepare the workplace, this process takes only 10-15 minutes. In this article, we will discuss all the nuances of the procedure, from the choice of accessory to the final polishing of the surface.

There is a misconception that cheap films protect as well as tempered glass. In fact, hydrogel films only save from micro scratches, while tempered glass takes on the impact energy when falling, preventing the destruction of the display matrix. Properly selected and pasted glass retains the sensitivity of the touchscreen and oleophobic coating, ensuring comfortable use of the smartphone.

Choosing the Right Glass Protection for Xiaomi

The first and most important step is to buy the right accessory.The market is oversaturated with offers, but for Redmi and POCO devices, it is important to consider not only the screen diagonal, but also the type of matrix. If your smartphone has curved edges (2.5D or 3D), a regular flat glass will only cover the center part, leaving the sidewalls vulnerable and creating a rainbow effect on the edges.

Pay attention to the hardness of the material, which is marked on the Mohs scale. Quality products have a score of 9H, which means resistance to scratches from metal objects. Cheap analogues are often made from ordinary plastic, which becomes cloudy after a couple of weeks of use. Also critical is oleophobic impregnation, which allows the finger to slide easily on the screen, and greasy marks do not remain on the surface.

For models with built-in underscreen fingerprint scanners (such as the Xiaomi Mi or Redmi Note Pro series), you need to choose glasses marked "Full Glue" or special versions for scanners. Thick windows can block the sensor, and you will have to constantly enter a password. In some cases, you need to re-register the fingerprint after installing protection.

• 🛡️ Full Cover: The glass is painted in the color of the screen and covers the entire visible area, including the curves.
• 💧 Hydrogel film: suitable for curved screens, but gives weak protection against impacts.
• 🔍 Scanner compatibility: a mandatory requirement for models with an ultrasonic or optical scanner in the display.

⚠️ Note: When buying glass for Xiaomi with a hole-punch cutout, make sure the cutout matches the diameter. In some models, the camera is offset and the protective glass can overlap the lens or proximity sensors.

You don't have to chase the lowest price. Cheap glass often has poor adhesion of the adhesive layer, which causes the "mustache" - peeling edges - to appear in a week. It is better to choose a product of the middle price segment from proven brands of accessories specializing in Xiaomi technology.

Preparation of the workplace and tools

The success of the surgery depends 90 percent on the conditions in which you glue the glass. The main enemy of the perfect glue is dust. Even a microscopic villi trapped under the glass will create a noticeable air bubble that cannot be removed without re-painting. So choose a room with minimal air movement: close the windows, turn off the fan and air conditioner.

The best place to work is in the bathroom, where the tiles and the humid air settle the dust, and the concentration of the dust in the air is minimal. Before starting the procedure, wipe all horizontal surfaces with a wet cloth and let them dry. Turn on bright lights in advance to see the smallest contamination on the screen.

You'll need a basic toolkit, which usually comes with quality glass, but you'll better prepare your own for reliability. Be sure to find a tape, preferably a wide stationery or paint, that will be useful for removing dust from the screen and the glass itself during operation. Also prepare a lilaless wipe made of microfiber.

Don't forget to wash your hands with soap and degrease them with an alcohol-containing solution. Fat marks from your fingers can remain on the edges of the glass or screen, which makes it harder to stick. If you have long nails, be extremely careful not to scratch the screen when you manipulate.

Step-by-step: how to glue glass without bubbles

The installation process requires calmness and precision of movement. Don't rush to remove the protective film from the adhesive layer until you are sure that the screen is perfectly clean. First try on the glass on the off smartphone, combine all the cutouts under the speaker, camera and sensors. Make sure that the glass does not overlap the useful area of the display.

Now we're going to clean it up. Rub the screen with a wet wipe from the kit, removing all the stains. Then wipe it dry with the dry part of the napkin. Take a piece of paper or a special sticky sticker (if any) and walk around the screen, collecting the smallest specks of dust. Light up the screen with a flashlight at an angle to see the remaining villi.

Take the bottom protective film off the adhesive layer of glass. Do this quickly but carefully, trying not to touch the adhesive surface with your fingers. Place the glass above the screen, focusing on the speaker and edges of the body. Once you touch one side of the screen, the glass will stick itself, spreading air. If you are confident in positioning, just lower the glass on the screen.

Once the glass is down, take a plastic card or a special spatula from the set. Start smoothing from center to edge, expelling air. Movements should be confident, but not too strong, so as not to damage the matrix. Pay special attention to the edges, which is where the air pockets are most often left.

• 🧹 Dust removal: If dust gets under the glass, use Scotch to "pull" it, raising the edge of the glass.
• 💨 Extracting air: move from the center to the periphery in circular movements.
• 👀 Control: Constantly check the result in side lighting.

If the air bubbles are still there, don't worry. Small bubbles can disappear on their own within a few minutes. 24-48 You can try to squeeze the big ones gently to the edge, but the key is not to push the screen too hard, you can use soft tissue.

Features of gluing on curved screens (3D/2.5D)

Owners of Xiaomi and POCO’s flagship models often face the problem of standard glass not sticking to the edges because of the display’s bending, which creates what are called “rainbow” zones or white bands around the perimeter, because hard glass cannot replicate the geometry of the screen.

So these devices have solutions for them, like UV-adhesive glass or flexible hydrogel films, and the UV glass is fixed with liquid glue that hardens when exposed to an ultraviolet lamp, which provides the perfect fit throughout the area, including the curves, and maximum protection against impact.

The process of installing UV glass is more complicated and requires caution. Liquid glue can leak into the speaker or charging connector if you do not protect these holes. So before you start, be sure to seal all the holes with paint tape. After applying the glue and installing the glass, it is fixed with the UV lamp for a few minutes.

⚠️ Attention: Liquid UV glue can damage the oleophobic coating of cheap films or get inside the case if the screen has cracks. Use this method only if you are confident in your skills.

The alternative is soft glass (hybrid), which is polymer-based, easier to stick to curves, but less durable than hardened glass, depending on which is more important to you: maximum protection from falls or aesthetics without white stripes at the edges.

Common Errors and How to Resolve Them

Even experienced users can make a mistake. One of the most common problems is the presence of large air bubbles immediately after gluing. If the bubble is large and in the center, try gently lifting the edge of the glass with tape, blowing on the adhesive layer (to remove static electricity and dust), and gluing again.

Sometimes users forget to remove the second protective film from the outside of the glass. If after gluing you see rainbow swelling or a feeling that the surface is rough, check if there is a transport film left on the glass.

Another mistake is not cleaning the screen properly, and the fat spots under the glass can eventually turn into noticeable marks that cannot be removed, and if you notice a greasy spot after you paste it, you will have to remove the glass, degrease the screen with alcohol, and glue it again (if the glue is still sticky).

Don't use aggressive chemistry to clean the edges of freshly glued glass. Alcohol or solvent can dissolve the glue around the perimeter, and the glass will start to flake off. Use only dry microfiber for finishing.

Care for protective glass and service life

The protective glass is a consumable that takes a hit, and over time, it gets micro-scratches and thins the oleophobic coating, and you can see that it's time to change the glass, you can see a worsened slip of the finger or noticeable scuffs in the frequent contact zone (usually at the bottom of the screen).

The life of quality glass is 6 to 12 months of active use, and then its protective properties are reduced. When glass is broken, it is important to remove all the fragments so that they do not scratch the main display, and this should be done carefully, using tape to collect small particles.

To extend the life of new glass, avoid contact with sand and abrasive materials. Carry your smartphone in your own pocket or use a cover with protective sides. The case not only fixes the glass, but also protects the edges of the smartphone when it falls on the edge.

💡

If you drop your phone frequently, change the protective glass at the first sign of cracks.Cracked glass is worse at cushioning the impact and may miss the chip on the main display.

Clean the screen regularly with a soft cloth, the accumulation of dirt and fat reduces tactile sensitivity and visual perception, and proper care will preserve the brightness and clarity of the image for many years.

Conclusion

Installing a security glass on a Xiaomi smartphone is a simple but important procedure that will save your budget from costly repairs.The main thing is not to be afraid, choose a quality accessory and keep clean during operation. With 15 minutes of time, you will ensure the security of the device for many months ahead.

Remember that even the most expensive glass doesn't give 100% guarantee when falling on a sharp stone, but it greatly improves the screen's chances of survival. Use cases in combination with glass for maximum protection.

💡

High-quality glued glass retains the sensitivity of the touchscreen and imperceptibly on the screen, creating a “feel” (use without protection).
