How to remove the glass of the Xiaomi Redmi phone: the full guide

Modern smartphones Xiaomi Redmi line famous for their stylish design and affordable price, but their glass screens remain vulnerable to falls. When the display appears cracks or “web”, there is a natural desire to replace only the top layer, leaving the original matrix, because it is much cheaper to buy a new module.

The process of separation of glass from the display requires a certain skill, specialized tools and compliance with temperature. In this article, we will discuss in detail how to remove glass from a Redmi Note or Redmi Pro phone safely so as not to damage the expensive matrix and plumes.

It is worth noting that this procedure does not belong to the category of simple repairs and requires care. If you have never understood the technique, you may need to contact the service, but if you are determined to act independently, then carefully study all the steps.

Diagnosis of damage and choice of replacement method

Before starting to disassemble, you need to accurately determine the nature of the damage. Often users confuse a broken protective glass (touchscreen) with damage to the matrix. If the image on the screen is clear, the colors are bright, there are no black spots or stripes, and the sensor responds to touch (even if intermittently), then you are lucky - the matrix is intact.

In situations where the screen shows ink stains, vertical stripes or part of the image is missing, replacing only the glass will not help, in such cases, a complete replacement of the display module assembly is required, since the liquid crystals are physically damaged.

⚠️ Warning: If you see colored stripes when you turn on the phone, or if the screen doesn't light up at all, but the backlight is working, it's a sign of damage to the plume or the matrix itself.

There are two main ways to restore: using a separator (a professional method with heating and cutting) and a method of separation without a separator (a riskier one, using a hair dryer and string). For a home craftsman who does not have expensive equipment, the second option is more often used, although it requires increased attention to heating temperature.

It is important to understand that the adhesive base (OCA-glue B-7000) It holds the glass very tightly. Without the glue softening properly, there's a high risk of breaking the glass into small pieces that are going to be extremely difficult to remove without scratching the matrix.

Tools and workplace preparation required

The quality of the repair depends on the preparation. You need a clean, well-lit place where no one will touch the elbow during fine work. Dust is the main enemy when gluing, so before you start, you better wipe the table with a wet cloth.

To successfully remove glass from Xiaomi Redmi, you will need the following set of tools:

• 🔥 Thermophen or building hair dryer (household hair dryer may not give the desired temperature in the body). 80-90°C).
• ✂️ Thin string (nichrome or guitar) or special knife for cutting glass.
• 💧 Dissolution liquid of adhesive (isopropyl alcohol or special solvent) OCA).
• 🧪 Plastic mediators and suction cup for neat opening of the body.
• 🧤 Safety glasses and gloves (shattered glass can fly in different directions).

The temperature should not exceed 100-110 ° C, as overheating can lead to burnout of the pixels of the matrix or damage to the battery located immediately below the screen.

Also prepare the small parts container and magnetic board so as not to lose the screws of different sizes that are found in the design of Redmi smartphones.

Dismantling of the display module from the housing

You can't remove the glass directly on the phone, because it will damage the internal components, and the first step is always to remove the display module.

Start by turning off your smartphone and retrieving SIM-Then heat the body perimeter with a hair dryer for a period of time. 2-3 Take a minute to soften the factory glue, gently slap the back cover (if it's glass) or use a suction cup to create a gap.

After removing the lid (or if you have a model with a metal case and access through the frame), you need to unscrew all the visible screws that attach the motherboard and plumes.

Carefully bend the plume latch and remove the connector. In some Redmi models (such as the Note series), the display can be glued to the frame around the perimeter, in which case, again apply heating along the edge of the frame and carefully poke the module with a mediator around the perimeter.

When the module is free, don't pull it sharply. Check if the fingerprint scanner plume is plugged in if it's embedded in the screen. Disconnect all remaining connections and remove the module for further work on the table.

The process of heating and separation of glass from the matrix

This is the most critical stage in deciding the fate of your screen: Put the extracted module on a flat surface with the screen up, turn on the thermophen and evenly warm the surface of the glass, holding the hair dryer at a distance of 3-5 cm.

The movements must be circular so that the heat is distributed evenly. Do not hold the hair dryer at one point for longer than 2-3 seconds. The goal is to heat the adhesive layer to a state of elasticity, but not to melt the plastic frame or polarization film.

When the temperature is reached, take a thin string or a special knife. insert it into the corner of the crack (or in the place where the glass has already broken off) and in smooth sawing movements lead the tool along the plane of the glass, pressing it against the glass, not against the matrix.

When you separate, you keep dripping isopropyl alcohol or solvent into the cutting area, which helps dissolve the glue residue and reduces friction, move slowly, without jerking, if you feel strong resistance, add heat, but don't use force.

Once the glass is removed, there's a layer of glue left on the matrix, which you have to remove, so you can warm the surface a little bit again and gently roll it off with your finger (in a glove) or a plastic blade, and you can wet the surface with alcohol.

Removal of glue residues and preparation for gluing

The surface of the matrix is the key to the absence of bubbles after assembly. OCA-The most difficult to remove is the adhesive, and use a special liquid (often sold as "De-gluer" or "De-gluer "OCA Remover") and a soft lilac-free napkin.

Rub the surface with light circular movements. If the glue is old and hardened, the procedure will have to be repeated several times. Do not use metal objects or hard brushes - you will irrevocably damage the polarization film.

After cleaning, carefully examine the matrix under bright light, it should not be villi, dust or smudges, any speck of dust that falls under the new glass will be visible as a dark dot.

Degrease the edges of the module frame with alcohol to make the new glue fall perfectly. Let the surface dry completely before applying the new adhesive.

Applying new glue and assembly

To fix the new glass, either a finished adhesive film (OCA) cut to size or liquid adhesive (B-7000, T-7000) is used, preferable for beginners, as it eliminates the appearance of bubbles.

If you use liquid glue, apply a thin strip along the perimeter of the frame, trying not to squeeze the excess inside. Combine the new glass with a frame starting on one side, and smoothly lower it, pressing it with your fingers from the center to the edges.

💡

Use an ultraviolet lamp to polymerize adhesive if you apply OCA-This will ensure maximum grip strength. 2-3 minute.

Once the glass is installed, the module must be fixed. Use special clamps or simply wrap the module tightly with rubber harnesses. Leave to dry for at least 2-4 hours (for liquid glue, the time can be up to 24 hours).

While the glue is drying, you can put the module back into the Redmi body, plug the plumes, check the touchscreen and images before you twist all the screws completely.

⚠️ Warning: Do not turn the phone on at full power immediately after assembly until the glue has finally polymerized.

The final stage is the installation of the back cover and checking the tightness (although it is difficult to achieve full water resistance at home).

Frequent mistakes and professional advice

Many users make the mistake of trying to remove glass without getting enough heat, which causes the glass to break into many small pieces that are almost impossible to remove without scratching the matrix.

Another common problem is the use of aggressive chemistry: Acetone or acetone-based solvents can melt the plastic frame of the display or damage the polarization film, making the image cloudy.

• 🚫 It is better to heat longer, but at a lower temperature than to overheat the matrix.
• 🚫 Do not use metal blades to clean the glue directly on the screen surface.
• 🚫 Avoid dust: Work in a room with minimal air movement.

If after the replacement you notice that the sensor is not working correctly (“gluts” or does not react in the corners), you may have damaged the touchscreen plume during installation or not fully inserted the connector.

💡

The quality of new glass and glue is often more important than the speed of the job, and cheap analogues can have worse sensitivity and oleophobic coatings.
