The Xiaomi Mi A2 Lite, also known as the Redmi 6 Pro in some regions, has proven to be a reliable device with a metal body. However, over time, even the best technology requires intervention: a broken screen, a worn-out battery or problems with the charging connector become frequent reasons for contacting the service. Understanding how this device is disassembled is critical for self-repair or simply to assess the complexity of work before visiting the master.
The process of dismantling Xiaomi Mi A2 Lite has its own features related to the design of the sandwich and the location of the plumes. Unlike budget models with a plastic back cover, it uses metal, which requires accuracy when heating and separating layers. Errors in the opening stage can damage the camera glass or break thin plumes, so be patient and the right tool.
In this article, we will look in detail at each stage of disassembly, from the removal of SIM-You'll learn what tools are needed, where the hidden screws are, and how to safely unplug the display module. Attention to detail at every step ensures that the internal components are safe.
Tools and workplace preparation required
Before you start any electronics manipulation, you need to have a safe workspace, you need a desk with good lighting and antistatic coating, or you need a clean, dry surface, and the chaos on the table is the main enemy of the repairman, because screws of different sizes are easy to confuse, and small parts can get lost.
For high-quality disassembly Xiaomi Mi A2 Lite you will need the following set of tools:
- 🔧 A set of Phillips screwdrivers (cross) sizes PH00 and PH000 hull-screw.
- 🔥 Thermolenta or hair dryer to heat the adhesive base of the display (temperature near 80-90 degree).
- 🛠 Plastic mediators, suction cup and thin metal scalpel for opening the body.
- 🧲 Magnetic mat or organizer for sorting screws by disassembly stages.
Pay special attention to the suction cup and the mediators. Metal tools should be used with extreme caution so as not to damage the internal plumes or shorten the contacts on the board. Plastic is safer in this regard, although it requires more effort to stratify.
💡
Use isopropyl alcohol to soften the glue if the hair dryer is not on hand, but act carefully so that the liquid does not get on the electronics.
Primary dismantling: Removal of the back cover and battery
Disassembly begins with extraction SIM-So you have to pull out two visible screws at the bottom of the case, next to the charging socket, to allow air to flow in and avoid damage to the antenna plumes, and then you have to unscrew the two visible screws at the bottom of the case, next to the charging socket, and they hold the back metal panel.
Next comes the most critical phase of the initial opening: the Xiaomi Mi A2 Lite's rear cover is glued around the perimeter. Heat the edges of the device with a hairdryer, evenly distributing heat so as not to overheat the display matrix on the front side. Use the suction cup to create a gap, and carefully drive with a mediator or a thin blade along the seam.
⚠️ Warning: Do not try to force the lid without warming the glue.The metal may deform, and the glass of the main chamber located in the corner often cracks when the body is bent sharply.
Once the lid is removed, you'll see the battery and the bottom board, and before you turn off the plumes, you need to unscrew some screws that lock the metal clip plates, and only after they're removed can you safely disconnect the battery connectors and the bottom speaker.
Removal of the display module and disabling the plumes
To gain full access to the motherboard, it is often necessary to remove the display module. In the design of the Xiaomi Mi A2 Lite, the screen is also held on adhesive basis. The procedure is similar to removing the back cover: perimeter heating and neat delamination with the mediator.
The challenge is that the plume of the display and the touchscreen, which are underneath the frame and connect to the board on top, and when you lift the module, don't make any sudden movements upwards, you first have to bend the module, like a page of a book, to access the connectors.
To turn off the plumes, use a plastic blade. Metal tweezers can damage the contact pads on the board or the connector itself. Once all the cables are disconnected, the module can be completely removed.
| Component | Type of attachment | Difficulty withdrawal | Risks. |
|---|---|---|---|
| Back cover. | Glue + 2 screws | Medium | Metal deformation, cracked glass of the chamber |
| Display. | Perimeter glue | Tall. | Trail rupture, matrix damage |
| Battery | Adhesive tape | Low. | Battery puncture, fire. |
| Maternity fee | Screws + plumes | Medium | Damage to small SMD components |
☑️ Safe disassembly of the display
Access to motherboard and subscreen speaker
The Xiaomi Mi A2 Lite motherboard is covered with a metal screen that acts as protection and heat sink, requiring many small perimeter screws to be unscrewed to remove it, and it is important to remember their location, as they can be of different lengths.
Under the main screen of the board are the main components: the processor, memory and communication modules, and there is a connector for connecting the main camera plume, and if your goal is to replace the camera, then further deep disassembly of the board is not required, just unscrew the lens locking plate.
The underscreen space is occupied by a speaker and a vibrator, and the speaker in this model is quite loud, but over time the membrane can damage, and to replace it, you need to unstick it from the frame (it is held on double-sided tape) and disconnect the contact pens.
⚠️ Warning: Avoid static electricity when working with the motherboard. Use an antistatic bracelet or periodically touch a grounded metal object.
The vibromotor is located at the bottom of the body, often under the lower board. Its replacement is simple, but requires careful handling of a thin plume that goes to the main board.
Replacement of the charging connector and lower board
Charging problems are one of the most common causes of disassembly. In the Xiaomi Mi A2 Lite, the connector is soldered on a separate board that is mounted with screws to the bottom of the body, which makes it easier to repair: no soldering, just replace the assembly.
To replace, remove the old board by disconnecting the main plume going to the "mother." Pay attention to the state of the plume itself: if it is rubbed or has crevices, it will also have to be replaced, otherwise the new connector will not work.
Set a new circuit board, making sure that the contacts of the speaker and vibration are tightly pressed. Often the problem with bad sound lies in the loose attachment of the contacts of the lower board to the speaker.
Why does the smartphone not see charging after replacement?
Assembly of the device and verification of functionality
The Xiaomi Mi A2 Lite is assembled in reverse order, but requires even more care.The main rule is: do not tighten the screws to crunch.The metal body is easy to deform, which will lead to gaps or creaks when pressed.
Before the final fixation of the back cover, be sure to conduct the initial test. Connect the battery, turn on the device and check:
- 📱 Touchscreen operation throughout the area (check for "dead zones").
- 🔊 Sound in Dynamics and Conversational Dynamics.
- 📸 Focusing cameras and flash operation.
- 📶 Network signal and operation of Wi-Fi modules.
If all tests are successful, degrease the frame and display with alcohol, apply a new glue (B-7000 or special glue for displays) and tightly press the lid. Lock the device with rubber bands for 15-20 minutes before the initial grasp of the glue.
💡
The build quality directly affects the moisture protection and durability of the smartphone, so do not ignore the stage of degreasing and fixing the glue.
Frequent mistakes in self-disassembly
Inexperienced craftsmen often make mistakes that make simple repairs costly. One of the biggest mistakes is ignoring the heating of the case. Trying to remove the display to the cold one causes 90% of the time it collapses.
Another common mistake is losing screws of varying lengths, so if you screw a long screw into a short hole, you can damage the board or the body, use a magnetic fork and sign the steps.
It is also common to forget to turn off the battery before disconnecting other plumes, which can short circuit and cause the power controller to fail, making repairs economically inefficient.
