Modern smartphones have become an integral part of our lives, and falling of the device often turns into a serious problem. This is especially true for popular models such as Xiaomi Redmi Note 12 Pro, where the screen takes up most of the front panel. Broken glass not only spoils the appearance of the gadget, but also makes it impossible to comfortably use touch functions. In this situation, the owner has two options: contact a specialized service or try to restore the device yourself.
The correct choice of repair method directly affects the durability of your device. Unprofessional intervention can lead to damage to the cables, broken contacts, or even failure of the motherboard. We will analyze all aspects of replacing the matrix, from the choice of components to the intricacies of assembly, so that you can make an informed decision.
Design features of the Redmi Note 12 Pro display module
Before you begin repairs, you need to understand what type of display you are dealing with. Smartphone Xiaomi Redmi Note 12 Pro Equipped with an AMOLED screen that features high brightness and deep blacks. This technology requires careful handling, since organic LEDs are very sensitive to mechanical stress and static electricity.
It is important to distinguish between two main types of damage: broken outer glass and a malfunction of the matrix itself. In the first case, it is often possible to replace only the glass (plywood), preserving the original matrix, which significantly saves the budget. In the second case, if the screen does not show an image or dead pixels appear, the entire display module assembly will need to be replaced.
β οΈ Attention: Even with minor damage to the glass of the AMOLED screen, there is a risk of cracks spreading to the matrix when trying to dismantle it yourself without special equipment.
The design of the module in this model involves a tight fit of the display to the frame using a powerful adhesive. This ensures tightness and protection from moisture, but greatly complicates the opening process. Any mistake in heating or prying can lead to deformation of the case.
Choice of components: original or copy?
The spare parts market is overflowing with offers, and choosing a quality item is difficult. For Redmi Note 12 Pro Original displays, high-quality replicas (OLED) and cheap analogues (LCD) are available. The original ensures perfect color reproduction, correct operation of the proximity sensor and sensor sensitivity.
Cheap LCD matrices, despite their low price, often have serious drawbacks. They may not support refresh rates 120 Hz, have distorted colors and a thicker frame around the screen. In addition, the operation of the light sensor with such substitutes is often unstable.
- π Original: Ideal quality, full compliance with factory specifications, high price.
- π OLED Reply: Good picture, but there may be differences in color calibration and touchscreen operation.
- π LCD Analogue: Low quality, lack of 120 Hz, thick frames, the most affordable price.
β οΈ Warning: Installing a low-quality display may cause the system to no longer recognize the fingerprint embedded in the screen due to differences in glass thickness.
When ordering spare parts online, be sure to check compatibility. Model Redmi Note 12 Pro has several modifications, and the cables may differ in the location of the contacts. An incorrect choice will result in the device being unable to connect.
- Perfect quality (Original)
- Balance of price and quality (OLED)
- Maximum Savings (LCD)
Necessary tools and workplace preparation
The success of the repair depends 50% on proper preparation. You will need a clean, well-lit work area, free from dust and small objects. Having a magnetic mat for parts will help you avoid losing screws and cables, which are very easy to lose during disassembly.
The list of required tools includes a soldering station or hair dryer for heating the glue, plastic cards or mediators, a set of screwdrivers and a suction cup. To work with thin cables, tweezers with rounded ends are useful to avoid damaging the contacts.
- π οΈ Construction or industrial hair dryer: for uniform heating of the adhesive layer around the perimeter.
- π οΈ Suction cup: to create a gap between the glass and the frame after heating.
- π οΈ Plastic cards: for cutting glue neatly without damaging internal components.
β οΈ Attention: Using metal tools to pry off the case is strictly prohibited, as this is guaranteed to damage the outer frame and leave deep scratches.
Before starting work, you must completely discharge your smartphone battery. This is critically important for safety, since if the cable with a connected battery is accidentally shorted, a fire or failure of the power controller may occur.
βοΈ Preparing to replace the display
Step-by-step instructions for replacing the screen
The replacement process begins with turning off the device and removing the protective elements. If your smartphone has glass installed, it must be carefully removed so that it does not interfere with access to the mounts.
