Xiaomi compact cameras (often called βsoap boxesβ) are budget-friendly but functional devices that sometimes require disassembly to clean the lens, replace the battery or repair buttons. However, their miniature body and fragile mounts make the disassembly process a non-trivial task. In this article, we will discuss in detail how to properly dismantle the case without damage to the board or display, what tools you will need, and what to look for when working with different models - from Mi Pocket to Mijia Mini. 4K.
It's important to understand that disassembling even a simple soapbox can lead to loss of warranty (if it's still valid) or failure of delicate components such as an image stabilizer or a microphone. We'll not only show the sequence of actions, but also point to hidden latches that often break when you open sloppy, and also give recommendations for storing screws and connectors so that they do not lose them in the process.
What Xiaomi models are βsoap boxesβ?
By the term "soap box" users usually mean compact cameras Xiaomi without interchangeable optics, which can be carried in your pocket.
- π· Xiaomi Mi Pocket - ultra-compact model with 1/2.3" matrix 7-zoom.
- π₯ Mijia Mini 4K β videocamera 4K, blogging.
- πΈ Xiaomi Smart Camera (not to be confused with the same name) IP-Cameras! β a hybrid camera and action camera.
- π Mijia Telescope Camera β a model with a telephoto lens for shooting remote objects.
Despite the external differences, most of these devices have a similar body design: a front panel with a lens, a back cover with a display and buttons, and a battery compartment. 4K, For example, it is different due to the presence of a rotary screen - we will talk about this separately.
If you are not sure about your model, check it in Settings. β About the device or on the sticker under the battery (if it is removable), this will help to avoid errors in disassembly.
Preparation for disassembly: tools and precautions
Before you start opening the case, prepare the workspace and tools.
- π§ Screwdriver kit: cross-haired (PH00 or PH0) flat (1.5-2 mm) for screws of different sizes.
- π§² Magnetic mat or screw container β to avoid losing small details.
- π Plastic blades (mediators) for disconnecting latches without scratches.
- π₯ Dryer or thermoair station - if the body is glued (relevant to the Mijia Mini) 4K).
- π§΄ Isopropyl alcohol (90%+) for cleaning contacts and removing glue.
We also recommend using an antistatic bracelet or at least periodically touching a grounded metal object, which will save the board from static discharge. If you are disassembling the device for the first time, take a photo of each step on the phone, this will help to properly assemble it back.
β οΈ Note: Some models (e.g. Mi Pocket) have hidden seals on the screws under the stickers, and if they are damaged, the warranty will be void.
Step-by-step disassembly of the body: from the battery to the motherboard
Consider the universal disassembly algorithm on the example of Xiaomi Mi Pocket. For other models, the nuances are indicated in separate sections.
Step 1: Removing the battery
If the battery is removable (as in most soap boxes), start by removing it:
- Turn off the device and take out the memory card (if installed).
- Open the battery compartment cover - it is usually fixed with a latch.
- Carefully pull the battery by the plastic loop (not for contacts!).
If the battery is not removable (like in the Mijia Mini) 4K), skip this step and proceed to disassemble the body.
Step 2: Rear cover removal
The back cover is usually mounted on 4-6 screws and a few latches.
- Unscrew all screws (they can be hidden under legs or stickers).
- Insert a plastic blade into the gap between the front and rear panels (start with the corner next to the connector). USB).
- Carefully drive the blade along the body, disengaging the latches. Do not force - if the lid does not respond, check if all screws are twisted.
In models with adhesive connection (for example, Mijia Mini) 4K) before disassembling, warm up the body with a hairdryer (temperature 60-70)Β°C) for 2-3 minutes to soften the glue.

Step 3: Unconnecting the plumes and removing the board
After removing the cover, you will see:
- A motherboard with connectors.
- Display plume and buttons.
- Speaker and microphone (if any).
To get the pay:
- Disconnect the battery connector (if it is not already disconnected).
- Carefully apply the display plumes and buttons with a flat screwdriver.
- Unscrew the screws that fix the board and remove it.
β οΈ Attention: In Mijia Mini 4K The swivel screen plume is extremely fragile. If you're not planning on replacing the screen, don't unplug it without having to.
| Model | Type of lid attachment | Number of screws | Features |
|---|---|---|---|
| Mi Pocket | Latches + 4 screws | 4 | Screws under the sticker next to USB |
| Mijia Mini 4K | Clay. + 6 screws | 6 | It takes a hair dryer to warm up. |
| Xiaomi Smart Camera | Latches + 5 screws | 5 | Fragile microphone plume |
Nuances of disassembly of specific models
Each model has unique features that are important to consider. Let's take a closer look at them.
Xiaomi Mi Pocket
This model differs:
- π Hidden screw under a rubber leg next to the connector HDMI.
- π A fragile speaker that is attached to the board with two thin wires.
- π· Moving lens - do not touch it when disassembling, so as not to knock the focus.
When building, pay attention to the gasket between the lens and the body - it is often lost, but is necessary for tightness.
Mijia Mini 4K
The most difficult model to disassemble is due to:
- π₯ Glue connection of the body - without heating the hair dryer, the cover will not be removed.
- πΊ Rotating screen - its plume is easily damaged with careless handling.
- π Built-in battery - to replace you will need a soldering iron or a special connector.
If you are disassembling this model for battery replacement, we recommend using a thermopaste when installing a new one - this will improve heat sink.
What if the screen does not turn on after assembly?
Cleaning and repair of internal components
After disassembly, you can start cleaning or repairing, and this is what most often needs attention.
- π§Ή Lens and matrix - remove dust with a soft brush or a spray of compressed air!
- π Battery β if it is swelling, replace it with a similar one (capacity and voltage should coincide).
- π Speaker and microphone β clear the contacts with alcohol if the sound is quieter or there are interference.
- π₯οΈ Payment - check for oxidation or damaged tracks. When soldering, use flux and low power soldering iron (no more than 30 watts).
To clean the battery contacts or plumes, use a cotton swab dipped in isopropyl alcohol. Do not use acetone or other aggressive solvents - they can damage plastic or rubber pads.
β οΈ Warning: If you notice dark spots or swollen capacitors on the board, do not turn the device on until they are replaced.
π‘
To clean the lens of greasy spots, use special wipes for optics or microfiber fabric with a drop of alcohol. Movements should be circular, from center to edges.
Building the machine: how to avoid mistakes
Collecting the soap box back is often harder than disassembling it.
- Check all the plumes β they should be securely fixed in the connectors (you will hear a click).
- Make sure the buttons are positioned correctly - they should stand in the slots without distortion.
- Twisting the screws cross-cross to avoid skewing the board.
- Check all functions before final assembly (turn on the device with the battery connected, but without the cover).
If new problems appear after assembly (for example, buttons do not work or the screen flickers), disassemble the device again and check:
- π Correct connection of all plumes.
- π§ Tighten the screws (but don't pull over!).
- πΆ Integrity of antenna wires (if any) Wi-Fi/Bluetooth).
π‘
The most common build error is the wrong installation of the display plume, and if the screen doesn't work, 90 percent of the time, it's the display plume that's the problem.
Frequent problems after disassembly and their solution
Even with a careful disassembly, there can be problems.
| Problem. | Probable cause | Decision |
|---|---|---|
| The machine is off. | Unconnected battery or power plume | Check the battery and board contacts |
| The screen flickering or not working | Display plume damaged | Replace the plume or check its connection |
| Buttons don't respond. | The button plume is not connected or bent | Reconnect the plume, check the contacts |
| The photos are blurry. | The focusing of the lens is lost. | Contact the service for calibration |
If the device after assembly overheats, most likely, you forgot to apply the heat paste on the processor or improperly fixed the radiator (relevant to the Mijia Mini). 4K). Disassemble the machine again and check the cooling system.
