Replacement of camera glass on Xiaomi Redmi 9 Pro: step-by-step instructions with photos and videos

The cracked or scratched camera glass on the Xiaomi Redmi 9 Pro is a problem that many smartphone owners face. Even when used carefully, falling on asphalt or hitting a hard surface often damages the fragile security glass above the camera module. Unlike replacing the display, this repair seems easier, but there are pitfalls: from choosing the right glue to the risk of damaging the plumes inside the case.

In this article, you will find a step-by-step photo guide, a list of tools you need, and tips on how to avoid common mistakes. We will discuss two methods of replacing: with a full disassembly of the phone (for advanced users) and with a minimum opening (for beginners), focusing on the choice of glass — original parts from Xiaomi vs. analogues from third-party manufacturers, and the nuances of pasting, so that new glass lasts for years.

If you've never taken a smartphone apart, don't rush to pick up a soldering iron or a screwdriver. In some cases, it's cheaper and safer to go to a service center. But if you're willing to take the risk, our guide will save you up to 70 percent of the cost of repair. The rule is patience and accuracy. One wrong move can damage a motherboard or a camera, and that's a whole other kind of money.

When to change the camera glass on the Redmi 9 Pro

Not every damage to the glass requires immediate replacement, sometimes it is enough to seal the crack with transparent tape to prevent dust from getting in, but there are cases where repair is mandatory:

• 🔍 Fractures with fragments that can injure your fingers or get inside the body, especially if the glass is starting to crumble.
• 📸 Artifacts in the photo: blurry, glare or dark spots due to the shift of the glass relative to the lens.
• 💧 Moisture under glass is condensate or water droplets that don't evaporate, and that's a sign of leakage.
• 🔧 The glass has moved away from the body and is kept on its word of honor, in which case the dust and dirt will quickly fill up the camera.

If the damage is purely cosmetic (such as minor scratches that do not affect the quality of the shooting), you can postpone the replacement, but remember: over time, the cracks diverge, and dust under the glass accumulates, worsening the camera.

⚠️ Warning: If the camera stopped focusing after the impact, or if the camera is turned off in the settings, the problem may be deeper, such as the camera module or the plume being damaged, in which case replacing the glass will not help.

Which glass to choose: original or analogue?

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

1. Original (OEM) – manufactured in the same factories as Xiaomi, but sold as spare parts, perfect in size and thickness, but more expensive (from 800 to 1500 rubles).
2. Quality analogues from proven brands (for example, Huaqin or Shenzhen YTO) Price - 300-600 rubles, the quality is almost equal to the original.
3. Cheap fakes (often brandless) can be incorrectly thick, cloudy over time or go away in a month, priced up to 200 rubles.

How to distinguish good from bad glass when buying:

• 📏 Check the thickness: the original is 0.21-0.25 mm. Too thin glass (less than 0.15 mm) will be brittle, too thick (more than 0.3 mm) - will not stand in the groove of the case.
• 🔎 Look at the edges: they should be evenly trimmed, without barbs. Cheap analogues often show signs of sloppy cutting.
• 💎 Put a tape on the glass and rip it off abruptly. If there's any trace of glue left, it's a fake (the original has an oleophobic coating).

Where to buy:

• 🛒 AliExpress is cheaper, but it's a long wait. Look for sellers with a rating above 98% and reviews with photos.
• 🏬 Local parts stores (like FixPrice or Chip and Deep) You can touch the item before you buy.
• 🔧 Service centers — sometimes sell glass wholesale at wholesale prices.

Important: for the Redmi 9 Pro (model M2007J3SC), glass from this modification is suitable only! Glasses from the Redmi Note 9 Pro or Redmi 9T will not fit due to the different sizes of the chamber unit.

Replacement tools and materials

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

In addition, the following may be useful:

• 🔧 Screwdriver T3 - if you need to remove the back cover.
• 🧲 Magnetic substrate - so as not to lose small screws.
• 📏 Loop or magnifying glass - to control the purity of the surface.

⚠️ Warning: Don't use metal tools (knives, blades) to smack glass! They can scratch the body or damage the plumes inside. Plastic mediators are safer.

💡

Before starting work, put the phone on a soft surface (such as a towel) so as not to scratch the screen when disassembling.

Step-by-step instructions for replacing glass

We will consider two methods: without removing the back cover (easier, but less reliable) and with a complete disassembly (more difficult, but guarantees a high-quality result).

Method 1: Replacement without disassembling the phone (for beginners)

This method is suitable if the glass cracked, but did not split into small fragments, and the adhesive layer is still held.

Step 1: Heating and removing old glass

Turn on the dryer at medium power and warm up the camera glass for 1-2 minutes, holding the phone at a distance of 5-10 cm The glue will become softer and the glass will separate more easily. Do not overheat - temperatures above 80 ° C can damage the plastic parts of the case.

Step 2: Removal of glue residue

Once the glass is removed, there will be traces of glue on the case.

• 🧴 Alcohol and cotton swab for small residues.
• 🧼 Soap solution - if the glue is strongly withered.
• 🔪 Wood sticks for mechanical removal (do not use metal!).

Carefully degrease the surface with alcohol and wipe with microfiber.

Step 3: Installation of new glass

Apply a thin layer of B-7000 glue along the edge of the chamber unit (not on the glass itself!). Press the new glass and hold for 2-3 minutes to hold the glue. For reliability, you can put a small load (for example, a coin) on the glass for 10-15 minutes.

⚠️ Warning: If you use a glue LOCA, it needs to be dried under a UV lamp for 5-10 minutes. Without the lamp, the glue will not harden!

Method 2: Replacement with disassembly of the phone (for experienced)

This is a much more reliable method, because it allows you to clean the inside and perfectly align the glass, but it requires you to remove the back cover, which increases the risk of damage to the plumes.

Step 1 Remove the back cover

Turn off the phone and dryer the back cover around the perimeter (especially at the buttons and connectors). Put a plastic mediator in the gap between the lid and the case and carefully drive along the edge. The lid is held on the latches - do not force!

Step 2. Turn off the camera plume

Once the lid is removed, you will see a metal screen covering the camera. Carefully unscrew the screws (usually 4-5 pieces, T3) and remove the screen. Then disconnect the camera plume by putting a plastic blade on it.

Step 3: Cleaning and installing new glass

Remove the old glass and the glue residue from the inside of the case (as in Method 1). Apply the glue on the new glass and press it, making sure it sits in the groove. Plug the camera plume back in and assemble the phone in reverse sequence.

🔧 Tip: Before assembly, check the camera by temporarily plugging in the plume. If the image is blurry, it may be that the glass is crooked or dusted.

Common Mistakes and How to Avoid Them

Even with care, you can make mistakes that will lead to a re-repair or breakage of the phone.

• 🔥 Overheating of the body — if you hold the hair dryer too close, the plastic can deform. Keep a distance of 5-10 cm and use average power.
• 🧴 Too much glue -- excess can leak into the body and stain the plumes. Put a thin layer of glue on the edge.
• 📏 Improper positioning of glass -- if the glass is curved, the camera will shoot with distortion. Check the slots of the case.
• 💨 Dust under glass -- even one mottled mottled mutt can ruin the look. Work in a clean room and use a sticky roller to remove the dust.

⚠️ Warning: If the glass was quickly removed after the replacement (within a week), the bonding technology was likely to have been disrupted.

1. Remove the glass and clean the surface of the old glue.
2. Use LOCA instead of the B-7000 – it holds better, but requires a UV lamp.
3. Before gluing, warm up the body with a hairdryer (this will improve adhesion).

🔍 How to check the quality of the installation:

• Light the flashlight at different angles - there should be no gaps between the glass and the case.
• Take test photos in bright light - there should be no glare or cloudy spots.
• Shake the phone – the glass should not “play” or make sounds.

💡

If the glass is installed correctly, it should be flush with the body, without gaps or backlashes, and any irregularities will lead to dirt accumulation and re-unsticking.

How much does it cost to replace glass in the service?

If you are not sure about your abilities, you should contact the service center.The cost of replacing the camera glass with the Redmi 9 Pro varies depending on the region and type of service:

💡 Tip: Before contacting the service, specify:

• Do they use original glass or analogues?
• Do you have a job guarantee (at least 1 month).
• Does the cost of a camera diagnostics (sometimes it takes some money)

⚠️ Warning: Official Xiaomi services may refuse repairs if the phone has been in informal repairs before or has autopsy marks, in which case they will offer a full replacement of the chamber module (cost – from 3 000 rubles).
