How to carefully remove the protective glass from Xiaomi Redmi 9 at home: 5 proven ways

The security glass on Xiaomi Redmi 9 eventually loses transparency, gets scratched or starts peeling off at the edges. Many users are afraid to remove it themselves for fear of damaging the original screen or leaving traces of glue. However, with the right approach, the procedure takes no more than 10 minutes and does not require professional skills.

In this article, you will find step-by-step instructions for different situations: when the glass is whole, cracked or glued to a heavy-duty adhesive. We will also analyze common errors that lead to scratches on the display, and we will tell you how to avoid divorces after removal. We will focus on the specifics of the Redmi 9 model - the location of the sensors, the cutout under the front camera and the sensitivity of the touch layer.

If you've never taken a safety glass off before, don't worry: 90% of your success depends on preparation and patience, and the key is to take your time and use improvised tools like knives or metal blades, and even if the glass is cracked, you can remove it without risking the screen, following our recommendations.

1.Preparation: What will be needed to remove the glass

Before you start the procedure, make sure you have all the tools you need. Don't use sharp metal objects - they can leave micro-cracks on the oleophobic screen covering. Here's the minimum kit that guarantees safe removal:

If you don’t have isopropyl alcohol, you can replace it with high-strength vodka (40%+) or white spirit, but with caution: the latter can damage the oleophobic coating with prolonged contact. For the Redmi 9, it is especially important to avoid liquids with abrasive particles – they scratch the touch layer, which leads to “dead zones” on the screen.

Professional advice: if the glass cracks, before removing, paste a wide tape (for example, packaging) and press it carefully, this will prevent fragments from breaking apart and make it easier to remove.

2. Method 1: Removal of the whole protective glass by means of a thread

This method is suitable if the glass is not damaged, but has started to recede along the edges or lost transparency. The advantage is minimal risk of scratches, since the thread evenly distributes the pressure. You will need a thin but strong thread (for example, a dental or fishing line).

Step-by-step:

1. Lift one edge of the glass with a plastic blade. 1-2 mm of clearance is enough.
2. Put the thread under the glass so that it lies parallel to the screen.
3. Hold the thread at both ends and slowly pull it parallel to the surface, like a saw of glue. Don't lift the thread up!
4. As you move, lift the glass with a spatula so that the thread does not get stuck.

If the glass doesn't lend itself, moisten the thread with isopropyl alcohol, it will weaken the adhesive. For Redmi 9, it's important to avoid the area around the proximity sensor (upper left corner) - there the glass is often more glued tightly.

💡

If you don't have a thread on hand, use a thin plastic film (like packaging) that's less effective, but it works too.

Method 2: Removal of cracked glass without fragments

The most difficult thing is cracked glass, and the main thing is to keep the shrapnel from falling under the original screen, because it can damage the matrix when you press it, and the combination of scotch and plastic blades will help.

Algorithm of action:

1. Stick tape strips on the glass so that they cover all the cracks. Carefully press, avoiding bubbles.
2. Heat the screen with a hair dryer 10-15 cm away for 30 seconds. This will soften the glue, but do not overheat - the temperature is above 50°C can damage OLED-The matrix (in Redmi 9 is used) IPS, But overheating is not desirable).
3. Put the tape and the glass in a plastic spatula. Move from edge to center.
4. If the fragments are left on the screen, remove them with the sticky side of the scotch, not with your fingers!

After removal, be sure to check the screen for microscopic squirts, and then swipe it with your glove on it, and if you feel roughness, you've got some glass particles left.

• 🔍 Light the screen at an angle with a flashlight - the fragments will cast shadow.
• 🧴 Wipe the surface with a napkin dipped in alcohol and repeat the check.

Method 3: Softening the glue with heat (for "stiff" glasses)

Sometimes the protective glass is glued so tightly that neither the thread nor the shoulder blade helps, and in these cases, the thermal method becomes the only solution, and it is also suitable for UV-adhesive glasses, which are used in some premium protective films.

Process technology:

1. Turn on the dryer at a medium power (air temperature ~40-45°C). Keep it at a distance of 10-15 cm from the screen.
2. Heat the glass for 1-2 minutes, evenly waving a hair dryer over the entire surface.
3. Try to smack the glass with a blade. If it doesn't respond, repeat the heat for another 30 seconds.
4. Once the glass starts to move away, continue to separate it with a plastic tool, without stopping heating.

⚠️ Note: Do not use a building hair dryer – it gives a temperature of over 100°C, which can melt the Redmi 9’s plastic frame or damage the display, and avoid heating the speaker and microphone area (the bottom of the phone) – there are thermally sensitive components.

After removing the glass, let the phone cool for 5-10 minutes before cleaning. A sharp temperature drop can cause condensation under the screen.

5. Screen cleaning after glass removal: 3 critical errors

Even if you can remove the glass without shrapnel, improper cleaning can ruin the whole result.

⚠️ Warning: Never use wet wipes for machinery -- they contain silicones that leave a greasy film -- this film prevents new glass from sticking and collects dust.

• 🧼 Soap or detergents - they destroy the oleophobic coating, which causes the screen to get dirty faster.
• 🧻 Paper towels – their fibers scratch the surface, even if invisible to the eye.
• 🔥 Hot water – can leak under the frame and cause corrosion of contacts.

The correct cleaning procedure:

1. Remove large residues of glue with a plastic spatula.
2. Apply a few drops of isopropyl alcohol to a napkin and wipe the screen in circular movements.
3. For persistent spots, use a soft toothbrush soaked in alcohol.
4. Allow the screen to dry for 2-3 minutes before applying the new glass.

If you have any stains left after cleaning, repeat the procedure with a dry microfibre wipe. For Redmi 9, it is especially important to pay attention to the area around the neckline of the front camera - there is often adhesive accumulation.

💡

After cleaning, check the screen for sensitivity! run a sensor test (e.g., via the ##6484## # engineering menu) and make sure all areas respond to touch.

6.How to avoid screen damage: tips for Redmi 9

The Xiaomi Redmi 9 screen has several vulnerabilities that are important to keep in mind when removing glass:

• 📱 Approximation sensor (top left corner) - if pressed hard, it can shift or turn off. If after removing the glass, the sensor stopped working, check the settings in Settings → System system → Sensors.
• 🔊 Speaker and microphone (bottom) - avoid liquid entering the grilles. When cleaning with alcohol, hold the phone vertically.
• 🖥️ Oleophobic coating -- it's getting rid of aggressive solvents, and if the screen gets worse at repelling fat, the coating gets damaged.

If you are planning to put on a new glass, consider:

• 🔘 For Redmi 9 suitable glass with a cutout for the camera 3.5 mm (standard for this model).
• 💧 Use a spray to install (such as Easy Apply) to avoid bubbles.
• 📏 Line the glass on the power button - this is the most reliable reference point.

Compatibility test: Before buying a new glass, check if it supports 240 Hz touch sensitivity (a feature of the Redmi 9 screen).

7. Alternative methods: when nothing helps

If the standard methods didn’t work, try these custom solutions (with caution!):

• 🧲 Magnetic method: Put a neodymium magnet (like a speaker) on the back of your phone, in some cases it weakens the adhesive layer. Don't use magnets that are too strong, they can damage the compass!
• 🧊 Cold way: Put the phone in a bag and place in the freezer for 10 minutes. the glue will become brittle, but the risk of condensation is high.
• 🧴 Special solvents: products like Goo Gone are effective, but require careful flushing!

⚠️ Warning: If after all the attempts the glass is not removed and the screen begins to peel off with it, immediately stop the procedure. This is a sign that the protective glass is glued to the polarization layer of the display.

The cost of restoring the Redmi 9 screen in the official Xiaomi centers starts from 3,500 rubles (2026), but it is cheaper than buying a new phone.
