How to glue the security glass on Xiaomi: a complete guide with life hacks

Why you need a safety glass and when to change it

The screen of Xiaomi's smartphone is one of the most vulnerable parts of the device. Even a slight drop on asphalt or contact with keys in your pocket can leave scratches on the oleophobic coating or cracks on the display itself. The protective glass takes the hit, keeping the original screen intact. But not all glass is equally useful: cheap films from PET quickly get cloudy and collect prints, and high-quality tempered glass with a high-quality glass. 9H-Hardness can withstand pressure up to 12 kg and does not distort the sensor.

When is it time to change old glass? If you notice microcracks at the edges that cling to the case and move further apart, or if the sensor has become less responsive, these are clear signs. Also a signal is loss of transparency (the appearance of a matte effect) or detachment of angles. On the new Xiaomi 14 and Redmi Note 13 Pro+ models with curved screens, even a minimal gap between the glass and the display can lead to dust accumulation and rainbow divorces in bright light.

It's important to understand that a protective glass is not a panacea; it doesn't prevent a strong impact on concrete, but it minimizes the effects of household damage, for example, if you fall from a height of 1 meter on a ceramic tiles, the glass has an 85 percent chance of cracking itself and the screen will remain unharmed (data from the Zagg and Spigen tests).

What kind of security glass to choose for Xiaomi: comparison of types

The market offers several types of protective glass, and the choice depends on the smartphone model and your priorities, POCO X6 Pro or Redmi 12 is a good standard. 2.5D-0.33 mm thick glass, but for flagships with curved displays (Xiaomi 13 Ultra, Mix Fold 3) you need to look for options with flexible edges or full cover (full cover).

Let us consider the main types:

• 🔹 2.5D Glass is a classic rounded-edge version, suitable for 90% of Xiaomi models, easy to glue, but does not cover the side edges of the screen.
• 🔹 3D/Full Cover – covers the entire screen, including curved edges, requires a precise fit to the model (for example, for Xiaomi). 12T Pro or Black Shark 5).
• 🔹 Oleophobic glass repels fat and fingerprints, which is relevant for users who often use a phone without a cover.
• 🔹 Impact-resistant glass with energy absorption - has an additional layer TPU, It's a system that extinguishes vibrations when impacted.
• 🔹 Private glass – darkens the screen when viewed from the side (at an angle of 30)°). Useful for protecting confidential information.

When choosing, pay attention to the thickness: too thin glasses (0.2 mm) are worse protectors, and thick ones (0.5 mm +) can worsen the sensitivity of the sensor. The optimal option is 0.33 mm. Also check the presence of the adhesive layer over the entire area (not only at the edges) to avoid bubbles.

Preparation of the smartphone: what to do before installation

Successful installation of the protective glass depends on 80% surface preparation. Even the smallest particles of dust or fat will lead to bubbles or detachment. Start by turning off your smartphone, this will help to avoid accidental touches of the screen while working. Then remove the case and SIM card (if it interferes with access to the screen).

Then proceed with the steps:

Remove old glass or film (if any) with a plastic card

Wipe the screen with a wet microfiber wipe, then dry

Use Scotch (included in glass kit) to remove dust and villi

Degrease the surface with an alcohol solution (isopropyl alcohol 70%+)

Check the screen under bright lights – there should be no slicing and particles-->

Pay special attention to the edges of the screen and the area around the front camera/dynamics. This is where most dust accumulates. If you have a dust absorber complete with glass, use it -- this is a special sticky tape that lifts microparticles from the surface.

💡

If you have a model with a subscreen fingerprint scanner (such as the Xiaomi 13T or Redmi K60 Pro), make sure the new glass is compatible with this technology. Cheap glasses can block the scanner's IR rays, which will stop it working.

Also prepare the workplace: the bathroom after a hot shower (the steam precipitates dust in the air) or the table next to the window in bright daylight is ideal. Avoid drafts and work with gloves so as not to leave greasy marks on the glass.

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

Now, to the most critical stage, unpack the glass and inspect it carefully for defects (scratches, chips).

• 📱 The glass itself with the protective film
• 🧴 Wet and dry wipes
• 🧲 Dust collector (sticky tape)
• 📏 Positioning stickers or frame
• 🪛 Plastic scraper for squeezing bubbles

Follow the algorithm:

1. Positioning stickers. If you have a frame or alignment stickers in the kit, stick them on the screen as instructed, and they will help you place the glass exactly.
2. Take the protective film off the glass. Take care to tuck the corner and slowly separate it, holding the glass behind the edges. Don't touch the glue side!
3. Install the glass. Take the glass by the side edges and apply it to the screen at a 30-45 angle.°. Start at the top (on the speaker side) and gradually lower down to avoid air intrusion.
4. Bubble squeezing. Use a plastic scraper or credit card to drive the air from the center to the edges. Move cross-sectionally, top to bottom, then left to right.
5. Final check, turn on your phone and check the sensor sensitivity, the fingerprint scanner (if any) and no iridescent tilts.

If you have small bubbles left after installation, don't panic. Most of them will disappear on their own after 24 to 48 hours, when the glue is evenly distributed, and the large bubbles can be removed by gently lifting the glass and re-adhesively.

Common Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes when installing a protective glass, and here are the most common ones and ways to prevent them:

Another common problem is rainbow sliding around the edges of glass, which is caused by uneven distribution of glue, or if the glass is thinner than it should be, and only if it is replaced with a better glass with a full adhesive layer, it will help.

💡

If the sensor is less responsive after installation, check if the glass is compatible with your Xiaomi model. Some glasses block the IR port for gestures or reduce the brightness of the screen by 5-10%.

Features of installation on the model with curved screens

Xiaomi smartphones with curved displays (Mi 11 Ultra, Mix 4, 13 Pro) require a special approach. 2.5D-The glass won't cover the edges, leaving them vulnerable:

• 🔄 3D-flexible edge glass covers the entire screen, but is more difficult to install, requires precise positioning and often comes with a frame to align.
• 🔄 Full Cover glass - completely covers the screen, including the curved parts, can slightly reduce the sensitivity of the sensor at the edges.

When installing on a curved screen, follow additional tips:

1. Use the positioning frame that comes with it. It helps align the glass along the curvature of the screen.
2. Heat the edges of the glass with a hair dryer (temperature not higher than 40 ° C) - this will make it more flexible and help to stick better.
3. To squeeze out the bubbles, use a soft silicone scraper to avoid damaging the curved edges.
4. After installation, do not wear a case for 12 hours - this will help the glue to be evenly distributed.

On models with a subscreen front camera (such as the Xiaomi Mix 4), avoid metallic-layered glass, which can degrade the quality of selfies.

If you are unsure of your skills, contact Xiaomi's service center.Installation 3D-glass on a curved screen costs about 500-800 rubles, but guarantees the perfect result without bubbles.

How to Care for a Safety Glass to Last Longer

The life of a protective glass depends not only on its quality, but also on its maintenance. Here are some rules that will help to prolong its life:

• 🧼 Clean the glass regularly. Rub the glass with a microfiber wipe 1-2 times a day. Use alcohol wipes (no more than 70% alcohol) to remove greasy traces).
• 📵 Avoid abrasives. Don't put your phone down on sand, gravel or other rough surfaces. Even small particles can leave mycroscraps.
• 🔋 Do not use your phone in extreme temperatures (-10°C and below) the glass becomes brittle and in heat (+40°C) the adhesive may lose adhesion.
• 🛡️ A case with elevated edges (like the Spigen Tough Armor) will protect the glass from chipping when falling.
• 🔄 Change the glass in time. If you have deep scratches or cracks, don't wait for them to spread out -- replace the glass in advance.

Note that the oleophobic coating on the glass wears off over time (usually after 6-12 months). If the screen becomes quickly dirty, you can restore the coating with special formulations (for example, Liquid Oleophobic Coating from Whoosh!).

💡

Don't use paper wipes or clothes to clean the glass, they contain fibers that scratch the surface. The best option is microfiber wipes that come with a smartphone.

What to do if the glass is broken or broken

If the protective glass is cracked, it needs to be replaced as soon as possible, sharp edges can injure your fingers, and cracks can spread over time, making visibility worse.

⚠️ Warning: Don't try to "glue" cracked glass with superglue or tape! this can damage the original screen and make it unsuitable for further protection.

To remove old glass:

1. Take a plastic card or mediator and gently tuck the glass from the corner.
2. If the glass does not lend itself, heat it with a hair dryer (temperature to 50 ° C) - this will soften the glue.
3. After removal, remove the glue residues from the screen using isopropyl alcohol.
4. Check the screen for microcracks, and if you have any, you should contact the service for diagnostics.

If the glass has broken off at the edges, but it's still intact, you can try re-gluing it.

1. Carefully lift the detached edge and apply a drop of glass glue (for example, LOCITE 406) under it.
2. Press the glass and squeeze the bubbles with a scraper.
3. Secure the edge with tape for 12 hours.

If the detachment occurred due to poor-quality glue or dust, it is better not to take risks and install a new glass.
