Replacement of camera glass on Xiaomi Redmi Note 9 Pro: detailed instructions with photos and tips

A crack on the glass of the Xiaomi Redmi Note 9 Pro camera is a problem that many owners face. Even a small chip can spoil the appearance of a smartphone, interfere with photos and eventually lead to dust entering the module. The service center will charge from 1,500 to 3,000 rubles for a replacement, but with the tools and accuracy, you can perform the procedure yourself.

In this article, you will find step-by-step instructions with photos, a list of necessary tools, tips for choosing parts and typical mistakes that beginners make, and we will also learn how to remove old glass, prepare the surface and install a new one so that the result is as good as in the workshop.

⚠️ Important: If a crack in the glass is accompanied by a broken camera, the problem may be deeper - the module itself or the plume is damaged. In this case, replacing the glass will not help, and you will need a diagnosis in the service.

The glass of the Redmi Note 9 Pro camera is not just a security element, but part of a sealed module (IP53), Otherwise, over time, condensate will accumulate inside, and we'll show you how to minimize the risks and achieve factory quality repairs.

Which glass to replace: original or analogue?

There are three types of glass available on the market for the Redmi Note 9 Pro:

1. Original (OEM) — They are removed from donor camera modules, perfect in size and thickness, keep the factory tightness. Price: 800-1 500 rubles.
2. High quality analogues are made by third-party companies (for example, Huawei or Samsung), but they are suitable for parameters. Often come with a glue layer already applied. Price: 300-800 rubles.
3. Budget equivalents are cheap glass from China (for example, with AliExpress), can have an inaccurate fit, worse transparency or require additional processing, Price: 100-300 rubles.

For long-term results, we recommend original glass or high-quality adhesive-layer analogues. Cheap options often have to be sized, and their optical properties can degrade the quality of the photo.

🔍 How to Check Compatibility?

• 📏 Thickness: Original glass is 0.3–0.4 mm. Analogues can be thinner or thicker, which will affect focusing.
• 🔍 Transparency: Hold the glass to the light – there should be no cloudy areas or distortions.
• 🧲 Magnetic test: No metallic impurities in the original glass (not attracted to a magnet).

💡 Tip: When buying, check whether the adhesive layer is included in the kit (usually it is a bilateral tape). 3M If not, you'll have to buy it separately.

Replacement tools: What will be needed?

To replace the glass of the Redmi Note 9 Pro camera, you will need:

⚠️ Note: Do not use metal tools (screwdrivers, knives) - they can scratch the body or damage the camera plume. Plastic mediators are sold in smartphone repair kits (for example, iFixit or Xiaomi Tool Kit).

🔧 Additional accessories (optional but useful):

• 🔦 loope USB-Microscope – to monitor small details.
• 🧲 Antistatic bracelet – protection against static electricity.
• 📏 A rod is used to measure the thickness of new glass.

Step-by-step: how to remove old glass?

The process of removing damaged glass is the most critical step, and if you do something sloppy, you can damage the camera plume or the module itself.

Step 1. Heating the glass

• Turn on the dryer at minimum power and direct the flow of hot air to the camera glass.
• Keep the hair dryer at a distance of 5-10 cm for 2-3 minutes, evenly warming the edges.
• The goal is to soften the glue, but not overheat the body (maximum temperature - 80).°C).

Step 2: Breaking glass

• Take a plastic mediator and gently tuck the glass from any angle.
• Do not apply force - if the glass does not lend itself, warm it for another 1 minute.
• Once a gap appears, slowly drive the mediator around the perimeter, separating the glass from the case.

⚠️ Warning: If the glass is cracked, it may break when removed, in which case use transparent tape to glue the fragments before removal.

Step 3: Surface cleaning

• Once the glass is removed, there will be traces of glue on the case, and remove them with isopropyl alcohol and a microfibre wipe.
• Check if there are any small pieces of glass left – they can prevent the installation of a new one.
• Rub the surface with a dry wipe to remove moisture.

💡 Tip: If the glue is not good, use a wooden toothpick soaked in alcohol - it is softer than plastic and does not scratch the body.

Installation of new glass: a step-by-step guide

Now that the surface is ready, you can start installing new glass, and it's important to place the adhesive layer right here and avoid getting dust.

Step 1. Applying glue

• If your glass comes with a ready-made adhesive layer, remove the protective film and gently apply it to the body.
• If there is no glue, cut out a strip of bilateral tape (3M 467 or similar) by size of glass.
• Stick tape to the phone body, not the glass – it is easier to avoid displacement.

Step 2. Installation of glass

• Gently apply the glass to the glue, starting at one edge.
• Lightly press it with your fingers, but do not press hard - you can damage the fragile surface.
• Make sure there are no gaps between the glass and the body.

Step 3: Fixing and checking

• Place the phone under an incandescent lamp or hair dryer (without blowing) for 5-10 minutes - this will accelerate the polymerization of the glue.
• Check the camera: Take a test shot and make sure there are no clouds or glare.
• If the glass is set curve, gently tuck it with a mediator and reglue (during the first 10 minutes, the glue is still amenable to correction).

⚠️ Warning: After changing the glass, do not wash your phone under running water for 24 hours - the glue must completely dry, otherwise moisture will fall under the glass.

💡

The main rule when installing glass is to avoid dust under the glue layer, even a small motif can spoil the appearance or create glare in the photo.

Common Mistakes and How to Avoid Them

Even when working carefully, beginners often make mistakes that lead to re-repair or damage to the phone.

1.Overheating of the shell

• 🔥 Problem: Excessive heat wrenching can warp plastic elements or damage the camera plume.
• 🛠 Solution: Use a dryer at minimum power and keep it at a distance of 10 cm Optimal temperature - 60-70°C.

Dust entering glass

• 🌫 Problem: Dust or fibers of wipes can remain under glue, creating visible defects.
• 🛠 Solution: Work in a clean, well-lit place. Before installing the glass, wipe the surface with sticky tape (such as duct tape to remove dust).

3. Wrong glue

• 🧴 Problem: Using cheap or inappropriate glue (such as Moment or Superglue) causes the glass to detach or damage the body.
• 🛠 Solution: Use only bilateral acrylic-based Scotch (3M 467, Tesa 61396) or specialized glass glue (LOCA).

4. Damage to the camera plume

• 📸 Problem: If you sloppy removal of glass, you can touch the plume, which will lead to a black screen of the camera or artifacts in the photo.
• 🛠 Solution: If the camera does not work after replacement, check the plume for cracks. If damaged, you will need to replace the module (price - from 2 000 rubles).

💡 Tip: If you’ve never repaired your phones, practice on an old smartphone or watch the Redmi Note 9 Pro video disassembly on YouTube (e.g., Xiaomi Repair channel).

How to check the quality of the replacement?

Once the new glass is installed, you need to make sure that the repairs are successful.

• 📸 Camera test: Take a photo on the main and front cameras. The pictures should not be glare, cloudy spots or distortion.
• 🔍 External inspection: Look at the glass from different angles - it should fit tightly to the body, without gaps.
• 💧 Waterproof: Gently wipe the glass with a wet wipe. If condensate appears underneath, the leakage is broken.
• 📱 Functionality: Make sure that all sensors (such as a fingerprint scanner if it is near the camera) are working correctly.

⚠️ Warning: If dust or moisture appears under the glass after 1-2 days, the adhesive layer was applied incorrectly, in which case you will have to repeat the procedure with a new surface cleaning.

Critical error: If the camera stopped focusing after the glass was replaced, it was likely thicker than the original glass, in which case it should be replaced with a thinner one (the optimal thickness is 0.3-0.4 mm).

Should I change the glass myself or contact the service?

The decision depends on your experience, the tools available and the willingness to take risks.

🔧 When to contact the service?

• If you have no experience in electronics repair.
• If the camera glass is part of a sealed module (in some versions of the Redmi Note 9 Pro, the glass is glued to the lens itself).
• If after self-replacement there are problems with the camera (does not focus, there are artifacts).

💰 How much does a replacement cost in the service?

• In official service centers Xiaomi — 2 000-3 000 rubles (with a guarantee).
• In unofficial workshops – 1000-2000 rubles (without a warranty for spare parts).
• In communication salons (for example, the Messenger, MTS) – 2,500-3,500 rubles (often use non-original spare parts).

💡

If you decide to change the glass yourself, take a picture of the disassembly process at each stage, which will help you build your phone properly if something goes wrong.
