How to stick glass on your Xiaomi phone: from the choice of material to finish polishing

Broken glass on Xiaomi smartphone is a problem faced by every third owner of the brand, according to statistics of service centers 2023 The reasons are trivial: falling from a height. 1-1.5 You can put it on asphalt, pressure in your pocket, or even a factory marriage of the adhesive layer. But don't rush to carry it to the workshop, you can glue the new glass yourself, saving up to a few hours. 70% In this article, we will discuss all the stages of the process, from the diagnosis of damage to the finishing, taking into account the features of the Redmi Note models. 12, POCO X5 and flagship Mi 13.

It's important to understand that Xiaomi's glass sticker technology is different from other brands' repair because of the specific design. AMOLED-displays (such as Xiaomi) 12T) glass thinner 0.2 And the adhesive layer has a different viscosity, and we've taken these nuances into account and we've prepared a manual that's just like a budget Redmi. A2, And for the premium Mi Mix Fold. 3. Warning: the process requires patience – the average repair time takes 2-3 beginner-hour 40-60 minutes for experienced users.

Diagnosis of damage: when the glass can be glued and when the module needs to be replaced

Before you run for a new glass, assess the nature of the damage. Not all cracks are subject to local repair — in some cases, a complete replacement of the display module will be required.

• 🔍 A web of cracks without chips: if the glass is whole but covered with a grid of microcracks, it can be replaced separately from the matrix.
• 💥 Deep chips with matrix damage: if colored stripes or black spots are visible under the glass, this is a sign of damage OLED/AMOLED-This will require the entire module to be replaced.
• 📱 Legation of glass at the edges: common after falling by a corner, 80% of the time, it can be re-adhesive, but it's important to check if moisture has been exposed to the screen.
• 🔋 Sensor-disrupted cracks: If part of the screen doesn't respond to touch, the problem can be both in the glass and in the plume. Check performance through Settings → The phone. → Equipment test.

Pay special attention to models with ultra-thin glasses (for example, Xiaomi Civi). 3 or Redmi Note 11 Pro+). They have a protective layer that is all about them. 0.3-0.4 And if you hit hard, you can see the cracks often go all the way to the matrix. 45°. If you see rainbow stains under glass, this is a sign of damage to the polarization layer - you can not do without replacing the module.

⚠️ Note: On Xiaomi models with Always On Display (like the Mi 11 Ultra), even small cracks can cause the screen to overheat. → Battery → Battery status if the value exceeds 40°C in standby mode is a reason to contact the service.

2.Selection of glass and glue: what's right for Xiaomi in 2026

Xiaomi's parts market is oversaturated with fakes, so glass and glue must be chosen responsibly, and the biggest mistake for newcomers is to buy universal glass "fits all models," which in practice leads to sensor sensitivity issues or detachment through the sensing of the sensor. 1-2 Here are the criteria for choosing the right one:

• 📱 Precise model match: glass should be specifically designed for your modification. For example, the Redmi Note 10 Pro and Redmi Note 10 Pro Max use different glass because of the differences in the location of the front camera.
• 🔬 Glass thickness: For most Xiaomi 2020-2026 year of production is suitable glass thickness 0.5-0.7 The exception is the flagship models (Mi). 13 Pro, Mi Mix 4), glass 0.3-0.4 mm.
• 🧴 Type of glue: for AMOLED-display (POCO F5, Xiaomi 12) need UV-refractive 1.47-1.49. For LCD-screens (Redmi) 9A) fits in the usual B-7000.
• 🛡️ Protective coating: the best option is glass with an oleophobic coating 9H. They are longer than they are, and they are more resistant to scratches.

Among the proven manufacturers of glass for Xiaomi in 2026 stand out:

• OEM-Glasses (original) from Xiaomi - ideal, but stand on the 30-50% They're more expensive than their peers. 2 years.
• JK Screen is a Chinese brand with a good reputation. POCO X3 Pro and Redmi Note 11 have a minimum backlash when installed.
• ET Trade - budget option for old models (Redmi 7, Mi) A3). Quality is average, but the price is 2 times lower than the original.

The situation is simpler for glue: for 90% of cases, it is suitable UV-glue LOCA (for example, T-7000 or B-7000). The main thing is to pay attention to viscosity:

- 100-200 cps for thin glass (0.3-0.4 mm)

- 500-800 cps - for standard glass (0.5-0.7 mm)

- 1000+ cps – for repair of detachments (not for full replacement)

⚠️ Note: On models with ultrasonic fingerprint scanner (Xiaomi Mi 11, POCO F4 GT) You can't use adhesive with metal particles, and that will make the sensor inoperable".

3. Tools required: full checklist for repairs

The quality of the repair is 60 percent tool-dependent, and don't skimp on it, because cheap fixtures can ruin both the new glass and the phone itself, and here's the minimum set you'll need to replace the glass with Xiaomi:

Suction cups (2 pc, diameter 3-5 centimeter)|Plastic mediators (thickness) 0.1-0.2 mm)|Thermoplate or hair dryer (power) 1000-1500 Watt)|Tweezers with curved ends|UV-lamp (wavelength) 365 nm)|Scalpel or stationery knife|Alcohol isopropyl (99%)|Microfibre wipes (without pile)|Scapula for the separation of plumes|Magnetic propeller substrate-->

Let’s discuss the purpose of each tool in more detail:

• 🧲 Suction cups: needed for gently lifting the glass.For Xiaomi with curved screens (Mi 11 Ultra), take suction cups with a flexible edge.
• 🔥 Thermoplate/dryer: heats up the glue to 60-80°C. Optimum temperature for LOCA-glue — 70°C. Do not use household hair dryers – they do not give accurate temperature control.
• 💡 UV-Lamp: for polymerization of glue. The power must be at least 9 watts. Lamps 3 watts (as in nail kits) will not work - drying time will increase by 3 times.
• 🧴 Isopropyl alcohol: degreasing. It's important to use the 99% compound - 70% alcohol leaves divorces.

For models with waterproof housing (Xiaomi 13, POCO X5 Pro will require additional:

- Sealer to restore protection (for example, LOCTITE 577)

- Pressurity tester (can be replaced by immersion in water after repair)

💡

Before buying tools, check compatibility with your Xiaomi model through XiaomiUI. There are databases for disassembling specific devices.

Step-by-step: how to remove old glass without damage

This is the most critical stage. A mistake here can damage the matrix or the plumes. The main rule is: take your time. The average time of dismantling the glass is not enough — 30-40 Here's a detailed algorithm for beginners:

Step 1: Preparing the phone

• Turn off the phone and remove it. SIM-memory-card.
• Heat the screen with a hair dryer or on a heat tile to 60°C during 2-3 It'll soften the glue.
• Plug the protective film on the back cover so as not to scratch it during dismantling.

Step 2. Separation of glass

• Attach the suction cup to the bottom of the screen (near the connector). USB-C).
• Pull it up carefully - there should be a gap 1-2 mm.
• Insert a plastic mediator into the gap and slowly lead it around the perimeter, separating the glass.
• On models with curved screens (Mi 11), start with the long side – so there is less risk of damage to the matrix.

Step 3: Removal of glue residue

• Remove the glue residues from the matrix with isopropyl alcohol and microfiber.
• For hard-to-reach places, use a wooden stick wrapped with a microfiber.
• Check the integrity of the plumes – they should be clean and have no tears.

⚠️ Note: On Xiaomi models with built-in fingerprint scanner in the screen (POCO F4, Redmi K50) You can't use metal tools to clean. This can damage the sensor. Use only plastic or wooden blades.

If the glass is cracked but does not separate, use this method:

1. Apply a drop of superglue on the suction cup and attach it to the center of the glass.

2. Wait. 1-2 minutes until the glue is grasped.

3. Pull carefully - the glass must separate completely.

Installation of new glass: adhesive technology and polymerization

Now, the hardest part is installing a new glass, and there are three key rules to follow:

1. Complete cleanness of the working surface (dust or pile will lead to bubbles).

2. uniform distribution of glue (excess or deficiency will cause detachment).

3. Precisely center the glass (a 0.5 mm shift will spoil the appearance).

Step 1: Preparation of the matrix

• Clean the matrix with alcohol and wipe with microfiber without pile.
• Check for scratches - if there are, polish them with paste GOI (graininess 1-3 micron).
• Apply a primer for better glue clutch. LOCA-Use the same brand of primer.

Step 2. Applying glue

• For UV-glue: apply a thin layer (0.1-0.2 mm) all over the matrix. Use a plastic spatula.
• For B-7000: apply glue along the perimeter of the matrix with a strip 2-3 mm, retreat 1 mm from the edges.
• Make sure that the glue does not hit the plumes or speaker.

Step 3: Installation of glass

• Carefully place the glass on the matrix, starting at the top edge.
• Line it up the connector. USB-C front-facing camera.
• Press the glass evenly over the surface. Use a special press or heavy book (weight). 1-1.5 kilogram).

Step 4: Polymerization

• For UV-glue: light up the glass UV-lamp 3-5 Keep the lamp at a distance. 5-10 centimeter.
• For B-7000: Leave your phone under the press. 12-24 Don't turn it on at this time!
• Check the Sensor Sensitivity through Settings → Additionally. → Touch test.

💡

Use the "vacuum chamber" method to remove bubbles: place your phone in a plastic bag and vacuum the air into the air. 10-15 It'll help the glue spread evenly.

Finishing: polishing and leakproofness check

Once the glass is glued, there are small defects, like protruding glue on the edges, microbubbles or roughness, that need to be fixed before the phone is turned on first.

Polishing the edges

• Remove excess glue with a scalpel or a special knife for modeling.
• Polish the edges of the glass with polished paste 3M Finesse-it (grain) 3000-5000).
• For glossy surfaces, use wax polyrene - this will give the glass a factory shine.

Pressurization check

• For models with protection IP53/IP68 (Xiaomi 13 Pro, POCO X5 Pro) apply the sealant around the perimeter of the shell.
• Check the tightness by immersion in water on 10-15 seconds (no deeper) 30 centimeter).
• After the test, dry your phone in rice or silica gel. 1-2 hour.

Sensor calibration

• Restart your phone and check the sensor in the Settings menu → The phone. → Equipment test.
• If there are areas of insensitivity, calibrate through the engineering menu (code ##6484###).
• For models with high frequency sensor survey (240/360 Hz) may require additional settings in Settings → Display. → Frequency of touch.

⚠️ Note: On phones with infrared port (Xiaomi 12, POCO F3) After the glass is replaced, the remote control may stop working. This is due to a change in the bandwidth of the IR signal. Solution: calibrate the port using the Mi Remote application (section "Settings" → Additionally. → IR calibration").

7 Common Mistakes and How to Avoid Them

Even experienced craftsmen sometimes make mistakes when replacing glass with Xiaomi, and here are the most common problems and ways to prevent them:

Special attention is paid to models with curved screens (Mi 11 Ultra, Mi Mix 4).

Incorrect centering of the glass leads to uneven gaps at the edges.

Excess glue in the bending area creates a "jelly" effect when scrolling.

- Insufficient polymerization in angular zones causes detachment through 1-2 month.

For such models, it is recommended that:

1. Use special templates for centering the glass.

2 Apply glue in two layers: the first is liquid for the main area, the second is thick for the edges.

3. Polymerize UV-lamp in three stages: center, left edge, right edge.

8.Alternative methods: when it is impossible to glue the glass

In some cases, it is either impossible or not economically feasible to stick new glass.

1. Replacement of the entire display module

Relevant for models where the glass and matrix represent a single whole (for example, Xiaomi Black Shark 5). ₽ depending on the model:

- Guaranteed image quality.

- Preserving factory seals.

Cons:

High price (up to 50% of the cost of the phone).

- Data loss if you don't backup.

2. Installation of protective film instead of glass

Suitable for budget models (Redmi) 9A, POCO M3), where the cost of glass is 60-70% Modern film, like Whitestone Dome Glass, is hard. 9H And it's pretty much as protective as glass:

- Price in 3-5 sub-glass.

Possibility of installation without special tools.

Cons:

- Less strength when falling.

There may be problems with sensor sensitivity.

3. Exchange under the Xiaomi Care program

If your phone is warranty (up to 12 months from the date of purchase), you can use the exchange program. In 2026, Xiaomi offers a discount of up to 40% on a new device when you surrender the old one with a broken screen.

The phone must be activated and defined by the system.

- Screen damage only (body intact).

- A receipt or confirmation of purchase in the Mi Account.

For older models 2 years (e.g. Redmi Note) 8 Pro, Mi 9T) It's often more profitable to buy a used phone in good condition than to repair an old one. 3000-5000 ₽.

Differences in oleophobic coating (drops of water spread differently).

Microsats at the edges (seen at an angle in good lighting).

- Changes in color reproduction (especially in the AMOLED-screen).-->
