Popular action cameras Xiaomi Yi has earned a reputation for reliable devices, but active operation in extreme conditions often leads to the need for internal maintenance. Owners face pollution from the inside, battery failure or the need to replace the plume of the power button. Self-disassembly of the case allows you to save significant money on the services of service centers, but requires extreme accuracy and understanding of the design of the gadget.
The process of dismantling this model is not trivial, since the manufacturer did not provide for classic screws on the outside of the device. The entire structure is supported by hidden latches and adhesive joints, which makes the first stage the most critical. Incorrect movement or use of the wrong tool can lead to chipping on the plastic or damage to the internal plumes, so before starting work, you need to carefully prepare the workplace and tools.
In this guide, we will take a detailed look at the algorithm that will allow you to safely open the device, diagnose or replace components, and then assemble it back. You will learn about the specific nuances of the Xiaomi Yi Action Camera design that are not obvious at first glance, and get answers to the frequently asked questions on repairs.
Tools and workplace preparation required
Before you start a physical dismantling, it is essential to ensure proper conditions for work: the surface of the table should be clean, flat and well lit so that small details do not get lost and roll into hard-to-reach places. It is recommended to use an antistatic mat or just a clean fabric to avoid damage to electronics by a static charge.
To successfully perform the procedure, you will need a specific set of tools that are not always included in standard household kits. The main tool will be a plastic blade or mediator, since metal can leave scratches on the glossy body or damage fragile latches.
Special attention should be paid to heating tools. The adhesive base that fixes the elements requires temperature exposure to soften. The use of a hair dryer is permissible, but a building hair dryer or professional heat pad will provide more controlled and uniform heating, which will reduce the risk of deformation of plastic parts of the case when overheated.
☑️ Preparation for the dismantling of Xiaomi Yi
Here is a complete list of the necessary equipment for safe disassembly:
- 🛠️ Plastic spatula (spudger) or thin mediator for opening the body.
- 🔥 Hair dryer (household or construction) for softening the adhesive layer.
- 🔧 Precision screwdrivers (cross-haired) PH00, PH000).
- 🧲 Magnetic mat or organizer for screws of different sizes.
- 🧤 Antistatic gloves to protect electronics.
⚠️ Warning: Never use metal knives or blades to pick through the joints of the body.The metal slips easily and can damage the camera matrix or plumes located immediately below the plastic.
Primary dismantling and removal of external elements
We start by removing all removable parts that don't require disassembly of the body. First, remove the battery and the microSD card. Not only will this de-energize the device, but it will also free up space for manipulation. If the battery is swollen, be very careful not to damage the shell with the sharp edge of the compartment.
Then you take the lens off. Some Xiaomi Yi versions have a removable lens that gets twisted, others have it fixed. If your model is capable of taking the optics off, carefully twist it counterclockwise, which will open up the insides and make it easier to further separate the halves of the body, as the lens often interferes with full disclosure.
After removing the battery, look at the bottom of the chamber where the connectors are located. Here you may need to unstick the decorative pad or rubber plug if it prevents access to the screws. In most cases, the main fasteners are hidden under the logo or in recesses under the textured surface.
What to do if the lens is not removed?
The key to this is to understand that there may not be any external screws on the body, and many action cameras are designed in a snap-fit fashion, where the halves of the body are connected by tight latches around the perimeter, and trying to find non-existent screws can damage the plastic in places where they shouldn't be.
Opening the case: work with latches and glue
The most difficult step is to separate the front and rear of the body, and this requires carefully warming the perimeter of the device with a hairdryer. Do not direct a hot stream of air to one point for longer than 3-5 seconds, so as not to melt the plastic or damage the matrix. The movements should be circular, evenly warming the joint along the entire length.
After heating, insert a plastic blade between the front and rear panels. Start with the bottom or the side faces, where there is usually the least electronics. Move slowly, sliding the blade along the seam while slightly pushing the halves of the body. You will hear the characteristic clicks - these are plastic latches coming out of the engagement.
| Impact zone | Type of attachment | Risk of damage | Recommended instrument |
|---|---|---|---|
| Perimeter of the shell | Plastic latches | Plastic chip, latch breakage | Plastic spatula |
| Around the lens. | Glue + latches | Matrix damage, dust | Thin mediator |
| Button zone | Tight landing | Button deformation | Thin plate |
| Lower end | Latchers | Damage to connectors | Scapula with rounded edge |
When you separate the halves, do not make sudden movements. Inside the case, thin plumes pass, connecting the main board with buttons, a display (if you have one in your modification) and a Wi-Fi module. A sharp jerk can lead to a break in contacts, the restoration of which will require a microscope and a soldering iron.
⚠️ Warning: If the body does not diverge after passing the shoulder blade around the perimeter, do not use force.
Access to internal components and diagnostics
When you successfully remove the back cover, you'll have the main board and the battery, and unlike smartphones, the layout is denser and the elements are tighter, and the first thing you need to do is to disconnect the battery plume from the motherboard, and you need to do this carefully, by putting the connector on with a plastic tool, so that you don't damage the contact areas.
The main board in Xiaomi Yi is fixed to several screws. Usually, their number varies from 3 to 5 pieces depending on the revision of the device. After spinning the screws, the board is not removed immediately - it can be glued to a frame or fixed by a display plume. Carefully examine the perimeter of the board for hidden mounts.
To replace a Wi-Fi module or clean a speaker, you may need to remove the board completely. If your goal is simply to replace the battery, you often just need to push the board away without removing it completely. However, deep cleaning of dust that often gets under the lens requires a complete dismantling of all components.
Diagnostics of malfunctions at this stage include visual inspection of the board for oxides, bloated capacitors or charred contacts. Often the reason for not turning on the camera is not the battery, but the oxidation of contacts in the charging connector or on button.
Battery replacement and optics cleaning
Replacing the power source is one of the most common causes of disassembly. The battery in Xiaomi Yi is usually glued to the body with double-sided tape. Removing it will again require neat heating. It is strictly forbidden to smack the battery with metal objects, which can cause short circuits and fire.
Use a plastic card or a spatula to gradually separate the battery from the wall of the case. Move slowly, helping yourself with light heating. After removing the old element, clear the seat of glue residue with alcohol or a special cleaner. The new battery should be installed on a fresh layer of glue or bilateral tape.
If the purpose of disassembly was to clean the optics from the inside, act with utmost care. Dust on the matrix or inside of the lens creates black spots on all images. To clean, use a purge pear and special wipes for optics. Never blow on the matrix with your mouth - microdrops of saliva that have settled on the sensor will dry out and turn into indiscriminate spots.
💡
When installing a new battery, make sure that its connector is polarized. Although connectors often have foolproof protection, in budget electronics, the location of the contacts may differ from the original.
The assembly is done in reverse order. Before you finally snap the case, check if all the functions are working: is the camera on, is the Wi-Fi working, is the buttons responding, and this will save you time to re-disassemble in case of an error.
Assembly of the device and check of performance
The final step is assembly. Make sure all the plumes are tightly seated in their connectors and are fixed with clamping slats, if they are designed, the plumes should lie flat, without any clamping or tension, any twisting can lead to the break of contacts during operation.
When you connect the halves of the body, first combine one side, then gently press the perimeter to the characteristic snap of the latches. Don't be afraid to apply moderate force, the plastic in Xiaomi Yi is quite elastic, but make sure that there are no gaps. If there is a gap, do not close it by force - disassemble and check if the plume or screw interferes.
After assembly, do a test shot. Check stabilization, sound recording and data transmission over Wi-Fi. If the camera behaves strangely (heats, spontaneously turns off), you may have badly screwed some element or left the tool inside (joke, but check will not be superfluous).
💡
Quality assembly depends on the cleanness of the joints and the correct stacking of the plumes. Don't ignore even small details, as they affect the waterproofness and reliability of the device.
⚠️ Warning: If the camera doesn't turn on after assembly, don't rush to disassemble it again right away. 15-20 Sometimes after the battery is completely turned off, the power controller takes time to activate.
