How to replace the screen Xiaomi Redmi 6A: the full guide

Smartphone Xiaomi Redmi 6A has proven to be a reliable budget device, but its glass surface, alas, is not immune to accidental falls or mechanical shocks. Broken screen is not just an aesthetic defect, it is a direct threat to the security of your data and comfortable use of the gadget. Cracks have the ability to grow, and damaged touchscreen can stop responding to touch at the most inopportune moment.

Replacing a display module with your own hands is a real opportunity to save a significant amount of money that service centers charge for the work of masters. The process requires accuracy, but it is not very complicated if you have the necessary tools at hand and clearly follow the algorithm of actions. In this article, we will discuss in detail each step, from the preparation of the workplace to the final test of functionality.

Before you start disassembling, you need to clearly understand what you will change. In modern smartphones, including the Redmi 6A, the screen is a single module, where the matrix, glass and touchscreen are already glued together in the factory. Attempts to unstick the glass from the matrix at home almost always end up damaging an expensive matrix, so the replacement is done exclusively by the module assembled.

Diagnostics and selection of components for replacement

The first step before buying parts should be a thorough diagnosis of the current state of the device, you need to make sure that the problem lies in the module of the display, and not in the software failure or plume. To do this, try restarting the device, gently pressing on different areas of the screen or connecting an external monitor through an adapter, if such an opportunity is implied by the design, although for Redmi. 6A It is characteristic of the physical failure of the matrix during impacts.

When choosing a new screen, it is important to pay attention to the type of matrix. The original displays for the Xiaomi Redmi 6A are made using IPS technology, which provides excellent viewing angles and color reproduction. There are also copies on the market that can be made using TFT technology — they are cheaper, but have worse viewing angles and paler colors. Visually they can only be distinguished when the device is on, comparing the picture at an angle.

Be sure to check the equipment before payment.Ideally, the module should come with an already installed frame (body), since gluing old glass to a new matrix or reshuffling the matrix into an old case requires professional equipment and skills. Buying a module assembled with a frame greatly simplifies the replacement process and minimizes the risks of damage to fragile components during reglaciation.

⚠️ Warning: Don't buy screens without being checked by the seller.Even a new module can have broken pixels or touchscreen areas that are only visible after being connected to the board.

To successfully complete the operation, you will need a set of tools, the absence of which will make the process impossible or dangerous for the smartphone.

  • 🛠️ Set of screwdrivers (cross-crosses) PH000, PH00) hull-rotor.
  • 🔥 Industrial dryer or heating pad for softening glue.
  • 🎴 Plastic cards or mediators for opening the case.
  • 🧲 Magnetic screw-sorting mat.

Preparation of the workplace and tools

The quality of the repair depends on the organization of the workspace: the table should be clean, well-lit and free from foreign objects that can scratch the case or get lost. It is recommended to cover the surface with white paper or light mat so that the fallen small screws and details are immediately visible.

Safety is priority number one. Before any electronics work, you need to disconnect the smartphone from the charger. If the battery has visible damage, bloating or smell of the electrolyte, you need to work with it with extreme caution, because there is a risk of fire. The ideal option is to remove the battery immediately after opening the back cover, before you start working with the display plumes.

Special attention should be paid to the temperature regime when working with a hair dryer. Redmi 6A has a plastic back cover, which is easily deformed when overheated. The temperature of the air flow should not exceed 80-90 degrees Celsius, and you need to keep the hair dryer at a distance of 3-5 centimeters from the surface, constantly moving it to evenly warm the adhesive layer around the perimeter.

Rear cover removal process

Disassembly Xiaomi Redmi 6A It starts with the removal of the back panel. Unlike many modern smartphones, there are no hidden screws under the plugs, but there is a strong adhesive layer. SIM-cards and memory cards to free up interior space and reduce pressure at opening.

After the body perimeter is warmed up evenly, insert a plastic card or mediator at the junction between the frame and the back cover. It is better to start from the bottom corner, where there is usually a small gap or tray. SIM-Move the map along the side faces, carefully cutting the adhesive layer. Do not use metal tools at this stage, so as not to damage the plastic latches or the lid itself.

When all the side faces are free, gently lift the back cover. Don't pull sharply, as it may be glued to the fingerprint scanner plume (if the model is equipped with one) or other components. In the Redmi 6A model, the scanner is often located on the back, and its plume requires careful disconnection or careful extraction from the grooves.

What to do if the lid does not open?
If the lid fails after heating, don't use force. Add a little more heat, focusing on the corners. You can use a suction cup to create tension while you're working the mediator. A sharp jerk can cause a crack in the camera glass or damage to the internal plumes.> Disabling the battery and removing the protective screens, the inner device of the smartphone will open to your eyes. The first and most important action is to turn off the battery plume going to the motherboard, and neatly disconnect the conector from the mounting of the mount, which will usually remove the mounting of the mounting of the device from the other mount. It is important to remember or draw the location of each screw, as their length may differ. Wrapping a long screw into a short hole can cause the board to break down and the smartphone to fail. After dismantling the protective plate, access to the main plume of the display is opened. It is also fixed by the connector. Carefully disconnect it, starting from one of the corners, gradually loosening the connector. Do not pull the plume behind the conductor itself, only for the hard part of the connector. In parallel, check the condition of other tubes, such as the main tube or the main board.

If you purchased a screen assembled with a frame, the process is greatly simplified: You just need to move all the internal components (motherboard, battery, cameras, speakers) from the old frame to the new one. If you change only the glass with a matrix without a frame, you will need to carefully peel off the old matrix, clean the frame of the glue residues and install a new one using a special glue. B-7000 double-sided. When you move the components to the new frame, make sure that all the holes under the camera, speaker and sensors match. Lay the motherboard with screws, but do not tighten them until the end. Connect the display plume and the plume of the touchscreen (if they are separate) to the corresponding connectors on the board. Make sure that the connectors are up to the click and even. It is important to properly lay the plumes so that they do not clamp when installing the protective metal plate. Use tweezers to straighten the folds on the plumes. After you install the metal plates, install the final stacking stage, you will install them in the battery packing before the battery. Clean the perimeter of the frame and the lid itself of the residues of old glue with alcohol or a special solvent. Degreasing surfaces is a critical step, as the fat from the fingers worsens adhesion. Apply a thin layer of special glue (for example, B-7000) Or use a pre-sticked double-sided tape around the perimeter, carefully align the back cover with the body, starting at the top where the camera is located. Tightly press the lid around the perimeter. For better fixation, you can use stationery bands, wrapping them on your smartphone. 15-20 Do not turn the phone on or load it until the glue is completely dry, usually about an hour. ⚠️ Warning: Excess glue protruding from under the lid should be removed immediately until it freezes. Use a dry wipe or cotton swab lightly moistened with alcohol, but make sure that the liquid does not get inside the speakers or connectors. After assembly, conduct a comprehensive check of Xiaomi Redmi 6A. Check the sensor (test in the engineering menu), brightness, proximity sensor and speaker. Make sure that Wi-Fi and Bluetooth are stable, as antennas are often located on or near the back cover, and poor build can degrade the signal. Frequently asked questions (FAQ) Can you just replace the glass with the old matrix? It's theoretically possible, but it's not recommended at home. It requires the separation of the glass and the matrix with a special machine and liquid nitrogen, and the application of a new layer of layer. OCA-The risk of breaking the matrix when separated is more than 80% without experience. Why doesn't the sensor work after the replacement? The most likely cause is poor contact of the touchscreen plume in the connector. Try disconnecting and reconnecting the plume, making sure it's plugged in to the point, and the problem may be a defective new module or damage to the plume during installation. Do I have to reset the phone before changing? Technically, changing the screen doesn't require resetting, as it's a physical manipulation. However, if you're concerned about data safety or your phone is unstable, backing up data before work starts is a reasonable precaution. B-7000 And then you start to build, and the first thing you do is you get to 3-5 minutes, but the full strength of the glue is gaining within 24 In the first hours after assembly, it is recommended not to expose the smartphone to shocks or use it in dusty or wet conditions. Does replacing the screen affect moisture protection? The Redmi 6A's factory moisture protection is not fully restored when self-replaced. The glue provides basic spray protection, but immersion in water or a strong jet can cause moisture to enter through microslits.
