How to Remove and Replace Your Lens on Xiaomi: The Complete Guide

Damage to the main camera module is one of the most common reasons for contacting service centers owners of Xiaomi, Redmi and POCO smartphones. Cracks on the protective glass, scratches on the lens or shifting the focus can completely spoil the quality of images, making photos blurry or black. Users often look for a way to remove the lens to replace it themselves, but this process requires high accuracy and understanding of the design of the device.

It is important to note that in most modern smartphones, the lens is an integral part of the camera module and does not change separately from the sensor. Trying to remove only the glass lens without replacing the entire unit often leads to dust on the matrix, which finally disables the camera. In this article, we will discuss the nuances of diagnosis, necessary tools and algorithm of actions for those who decide to repair themselves.

Before starting disassembly, you need to make sure that the procedure is appropriate: If only the outer protective glass is damaged, and the module itself focuses and takes clear pictures, sometimes it is enough to replace only the glass. However, if the photo shows black spots, stripes or blur at the edges, a complete replacement of the module is required, ignoring these signs can lead to irreversible damage to the plume or board.

Diagnosis of damage and the need for replacement

The first step before any intervention is to be thoroughly diagnosed. Not always visible glass damage means that you have to change the entire expensive module. In some cases, the problem is software failure or contamination that can be fixed without disassembly. However, if you see physical chips or cracks penetrating into the body, the probability of needing a replacement is close to one hundred percent.

Notice the behavior of the camera app. If you start up with an error message or the image twitches, it may indicate damage to the stabilizer or the plume. In optically stabilized (OIS) models, even a minor impact can displace the lenses inside the module, in which case a simple cleaning will not help, you will need a physical replacement of the component.

⚠️ If after the fall in the photos appeared black spots that do not disappear when cleaning the glass, this means that the dust got inside the module. In 99% of cases, a complete replacement of the camera will be required, since it is almost impossible to disassemble the module at home without losing the tightness and quality of the optics.

To accurately determine the model of the camera that you need to order to replace, you can use system information, which will help to avoid buying an incompatible module, since even within the same line of Xiaomi can use different sensors from Sony or Samsung.

Tools and workplace preparation required

A high-quality repair is impossible without a specialized tool: Attempting to open a smartphone with a knife or a kitchen kit screwdriver will result in scratches on the body and possibly damage the battery. To work with modern electronics requires a set of precision tools designed to work with miniature screws and fragile plumes.

Special attention should be paid to the organization of lighting and cleanliness of the desktop. Microscopic dust dust, caught on the camera matrix during the replacement process, will be a noticeable defect in all future photos.

Below is a list of tools that should be on hand before starting the procedure:

• 🔥 A hair dryer or thermophene (to soften glue)
• 🔥 Set of suction cups and mediators (plastic blades)
• 🔥 Setting screwdrivers (Torx) T2, T3, T4, T5 cross-sized)
• 🔥 Tweezers with curved ends (antistatic)
• 🔥 Clay. B-7000 or T-7000 rear-lock

It is also highly recommended to use an antistatic bracelet or regularly touch a grounded metal object. Static electricity can instantly disable the power controller or the camera sensor itself, even if visually everything goes well. Component safety is the number one priority.

The process of disassembling the Xiaomi smartphone

Disassembly of modern Xiaomi smartphones begins with heating the perimeter of the back cover. The glue that it is glued to holds the case very tightly at room temperature. Heating to a temperature of 80-90 degrees Celsius softens the adhesive layer, allowing you to carefully separate glass or plastic from the frame without chipping.

When you remove the back cover, you get access to the insides, but you can't rush the camera module out. The first thing you need to do is turn off the battery. This is a critical step to prevent short circuits when you disconnect the plumes of the display or the camera. Any movement of the plume under voltage can burn the controller on the motherboard.

Then you have to unscrew the pins in sequence, and they close the plume connectors and protect them from accidental disconnection, and you have to act slowly, remembering the location of the screws, because they can vary in length and thread at different points in the body.

When you get access to the camera module, don't pull it right away. Often the module is further locked with glue or a tight fit in the frame. Easy swaying and using a plastic blade will help to free it. Remember, the force should be minimal.

Technology for retrieving and replacing the camera module

The moment of removal of the module requires special care: the camera is held on a connector that is inserted into the connector on the motherboard. To remove the lens (in this case, the entire module), you first need to gently lift the connector with a nail or a plastic blade, and then remove the entire unit from the seat.

When installing a new module, it is important to keep clean. Even microscopic tissue pile can spoil the frame. Before installing a new module, it is recommended to blow the landing place with a pear to clean the optics. Make sure that the new module's lenses do not have a factory protective film (if any, it should be removed).

The process of connecting the plume requires precision. The connector must stand up smoothly, without skewing. Once the module is in place, but before the plates are screwed, you can do an initial check by plugging in the battery and turning on the phone, but you need to do this very carefully, so as not to close contacts.

If you only change the outside glass of the lens (which is rare and requires special equipment), the process involves the use of ultraviolet glue and separator. For the average user, replacing the entire module is the only safe option.

Assembly of the device and check of performance

Once the new module is successfully installed and tested, the reverse assembly process begins, and it is important to remember to glue the body perimeter if the old glue has lost its properties. Using the B-7000, you can create an elastic and water-resistant (to some extent) seam.

The screws should be twisted cross-cross, gradually tightening them to ensure that the plates fit evenly.Do not tug the screws, especially in the plastic cases of budget Redmi models, as this can lead to cracks in the seats.

The final check includes testing all the camera functions:

• 📸 Autofocus (guidance on near and far objects)
• 📸 Optical stabilization (smoothness of video recording)
• 📸 The work of all lenses (width, TV, macro)
• 📸 Sound quality when recording video (microphone next to camera)

⚠️ Note: If the camera is focused after assembly, but the image is purple or green, the plume may not be fully inserted or damaged during assembly.

💡

After changing the camera, take several test shots under different lighting, sometimes the matrix defects are only visible against a uniform background (such as a sky or a white wall).

Common mistakes and risks of self-repair

Self-repair is always a risk. The most common mistake is to damage the plume when it is not carefully extracted. Xiaomi camera plumes are very thin and easily torn. If you hear a characteristic crunch or feel resistance, don't pull harder, but look for a hidden screw or lock.

Another common problem is leakage, because when you open the case, the smartphone loses its factory moisture protection, even if you glue the lid carefully, the IP68 or IP53 protection level will not be restored, and remember this and avoid moisture on the device after repair.

Using the wrong adhesive can also be fatal. Some types of adhesive release fumes that settle on the camera lenses and sensor, creating an indissoluble film. Use only specialized electronics adhesives that do not contain aggressive solvents.

💡

The main risk of self-replacement is the loss of warranty and the possibility of permanently damaging the plume or motherboard if there is no experience with microelectronics.
