Xiaomi camera disassembly: detailed instructions with nuances for different models

Disassembling a camera on a Xiaomi smartphone can be necessary for many reasons, from simple cleaning of the lens to replacing a damaged module or repairing a plume. However, this process requires accuracy and knowledge of the design features of a particular model. Unlike replacing a battery or display, working with the camera involves the risk of damaging fragile parts, from microscopic lenses to flexible plumes that are easy to tear when you carelessly move.

In this article, we will take a step-by-step look at the disassembly process, take into account the nuances for popular series (Redmi Note, POCO, Mi), list the necessary tools and warn against typical errors. We will pay special attention to safety: why you can not use metal tools near the lens, how to avoid dust on the matrix, and what to do if the camera stopped focusing after disassembly. If you have never done electronic repair, we recommend you first practice on a non-functioning device or contact the service center.

Preparation: tools and conditions for disassembly

Before you start disassembling, make sure you have everything you need, and even one tool that you don't have can damage the body or the internal components, and here's the minimum set:

• 🔧 Plastic blades (preferably a set with different thicknesses - from 0.1 to 0.5 mm). Metal mediators are not suitable: they scratch the body and can close contacts.
• 🔩 Screwdrivers with a set of bits: PH00, T3, T5 (Different Xiaomi models use different screws).
• 🧲 Magnetic mat or organizer for screws - to avoid losing small details. screws in Xiaomi smartphones often differ in length even in the same model!
• 🧴 Isopropyl alcohol (90%+) and lilac-free wipes for cleaning the lens and contacts.
• 🔥 Hair dryer or thermo-air station (if you want to unstick the back cover) The temperature must not exceed 80°C, otherwise the glue and plastic parts will be damaged.

Also, prepare the workplace: the desk should be clean, dust-free and debris-free. Ideally, use an antistatic mat or at least a grounded surface to avoid static discharge that can damage the camera matrix. If you disassemble a waterproof phone (such as the Xiaomi 13 Pro or Redmi Note 12 Pro+), keep in mind that once disassembled, the leakage will be broken and the device will lose its moisture protection.

⚠️ Note: Some Xiaomi models (e.g, POCO F5 or Redmi K60) They have hidden latches under the camera plumes, and if you pull the lid too hard, you can break the flexible cable or damage the antenna modules. Always check if there are any undetected screws or clips!

Step 1: Removing the back cover

The first and most important step is to carefully separate the back panel, which is glued to the back panel in most Xiaomi models, and it will require heating to remove it.

1. Turn off the phone and remove it. SIM-card and memory card (if any).
2. Heat the edges of the back cover with a hair dryer (keep it 5-7 cm, temperature 60-70°C). Do not direct airflow to the camera or display!
3. Insert a plastic blade into the gap between the lid and the frame (start at the bottom edge where the speakers are usually located).
4. Carefully drive the shoulder blade around the perimeter, separating the glue. If the lid does not lend itself, warm up again.

In models with an aluminum frame (for example, Xiaomi 12T or POCO F4 GT) the cover may sit tighter due to additional clips. In this case, it will take more effort, but do not apply force to the center of the cover – so you risk damaging the battery or plumes.

When you take the lid off, you'll see the insides of the phone. Pay attention to the location of the plumes and connectors, which are easily damaged if you sloppyly pull the lid. In some models (like the Redmi Note 11 Pro), there may be an extra layer of protective film under the lid - remove it carefully so as not to tear.

Step 2: Shutting off the battery

Before any manipulation of the internal components, be sure to turn off the battery, which will prevent short circuits and protect the phone from accidentally turning on during repairs. In most Xiaomi models, the battery connector is located at the bottom of the board and closed with black insulation tape.

Carefully put a plastic blade on the tape, and disconnect the battery plume. Don't pull the wires, just the connector! If the connector is sitting tight, you can sway it a little bit from side to side. In some models (like the POCO X3 Pro), the connector can be fixed by a latch, you have to bend it beforehand.

⚠️ Warning: If you accidentally close the battery contacts with a metal tool, stop working immediately and check the phone for overheating. In extreme cases, the battery may swell or ignite. Do not leave your phone unattended after an incident!

After the battery is turned off, it is recommended to wait 1-2 minutes to discharge the residual voltage in the capacitors on the board, and you can also press and hold the power button for 10-15 seconds to completely discharge the circuits.

Step 3: Dismantling the camera module

The camera module in Xiaomi smartphones usually consists of several parts: the main matrix (with lenses), auxiliary sensors (depth, macro, wide-angle) and a plume that connects all this to the motherboard. In budget models (for example, Redmi 10A), the camera can be a single unit, and in flagships (for example, Xiaomi 13 Ultra) – spaced in several modules.

Procedure:

1. Find the screws that attach the camera module to the board, usually 2-4 of them (depending on the model), the screws can be hidden under a protective film or a metal screen.
2. Then, put them away and put them away (and not be confused with other screws!).
3. Put a plastic blade on the camera plume and disconnect it from the circuit board connector. Don't pull the wires, just the connector itself!
4. If the module is glued (e.g. in POCO F3), gently slap it around the edges. Do not use metal tools near the lenses!

In models with a telephoto lens (such as the Xiaomi 12S Ultra), optical elements may fall out when handled carelessly. If this happens, do not try to insert them back yourself - calibration is required at the service center.

💡

If the screws don't unscrew, don't force them -- try putting a little isopropyl alcohol on the thread, which will help dissolve any possible corrosion or glue.

Step 4: Disassembling and cleaning the lens

If you want to clean the lens of dust or dirt, just remove the top lens. Most Xiaomi modules use it on a thread or latches. Here's how to do this:

1. Place the camera module on a clean napkin with the lens up.
2. Carefully scroll the top lens counterclockwise (if it is in a thread) or tuck the latches with a plastic spatula.
3. Wipe the lens with a wiltless napkin dipped in isopropyl alcohol. Don't use paper napkins or cloth - they scratch the coating!
4. Blow the inside of the module with compressed air (from the can) to remove the dust. Keep the balloon vertically to avoid fluid intake.

If you notice a scratch on the lens, replace it — polishing won’t help, it will only worsen the quality of the shooting. In multi-camera models (wide-angle, macro, telephoto), clean each lens separately, as dust can accumulate between them.

⚠️ Attention: Do not blow your mouth into the lens, the moisture from the breath will settle on the matrix and lead to blurring of the images.

Step 5: Replace the plume or camera matrix

If the problem is a damaged plume (for example, after a phone drop) or a faulty matrix, you will need a complete replacement of the module.

1. Buy the original camera module for your model. Make sure it’s compatible – even within the same series (like the Redmi Note 11 and Redmi Note 11 Pro), modules may differ.
2. Remove the old module as described in Step 3.
3. Install the new module in place, secure the screws (do not drag them!).
4. Connect the plume to the plug on the board. Make sure the connector sits before the click.

After the module is replaced, the camera may need to be calibrated.

1. Turn on your phone and open the Camera app.
2. Go to Settings → Additional → Camera Calibration (the path may vary depending on the version of MIUI).
3. Follow the instructions on the screen (usually you need to point the camera at a special camera). QR-code).

If the calibration didn't help and the images remain blurry, check if the module is properly installed, sometimes just a little shift in the socket to restore focus.

💡

After you change the camera, be sure to check its performance in different modes: main, macro, night and video. If artifacts occur in one of the modes, the module is installed incorrectly or defective.

Step 6: Build your phone and check

The phone is assembled in reverse order, but with some nuances:

• 🔄 Before installing the lid, make sure all the plumes are connected and not squeezed. In Xiaomi models with wireless charging (such as Xiaomi 13), check that the coil has not shifted.
• 🧩 If the lid is not tight, warm it up with a hair dryer and press it for 1-2 minutes.
• 🔋 After assembly, plug the battery in and turn on the phone. If it doesn't turn on, check if the battery contacts are closed.

After assembly, test the camera:

• Take pictures in different lighting conditions.
• Check the autofocus (point the camera at the object at a distance of 10-20 cm).
• Record the video and check if there are any tremors or artifacts.

If the camera is not working, take the phone apart again and check:

• Is the camera plume connected to the board?
• Is the matrix damaged (it should not be scratched or stained).
• Whether the plume is squeezed between the lid and the frame.

Frequent Mistakes and How to Avoid Them

Even experienced craftsmen sometimes make mistakes when disassembling Xiaomi cameras, and here are the most common ones and ways to prevent them:

Another common problem is the dust under the lens after assembly, and to avoid this, work in a clean room and use an antistatic mat. If you do get dust, don't try to blow the module after assembly, disassemble the phone and clean the lenses again.

If the camera becomes less focused after disassembly, it may have shifted the optical axis when the module is installed, in which case only re-disassembly and precise installation will help. In flagship models (for example, Xiaomi 13 Ultra), this may require special calibration equipment.
