Why does the Redmi Note 8 Pro screen break so often β and how much does it cost to fix it?
The Xiaomi Redmi Note 8 Pro screen is one of the most vulnerable parts of this smartphone. Despite the protection of the Gorilla Glass 5, falls from a height of 1-1.5 meters often end in cracks, "web" or complete sensor failure. The reason is not only the brittleness of the glass, but also in the design: thin body and lack of shock absorbing inserts between the display and the metal frame. Even a slight impact on the corner can lead to rupture of plumes or damage to the matrix.
The cost of screen replacement varies from 3500 before 12000 The price range is huge, not just in the region or the status of the service center, but also in the type of matrix being installed. 2-3 It is more expensive than analogues, but it guarantees the preservation of all functions: Always-on Display, the correct operation of the light sensor and the absence of "yellowness" after replacement. In this article, we will discuss where it is more profitable to repair, how to distinguish a fake from the original and why cheap repairs can turn into new problems.
Important: if after a fall, the smartphone does not turn on or the screen flashes / flickers, the problem may not be in the display, but in damage to the motherboard or disconnection of connectors. In such cases, diagnosis in the service is mandatory - self-disassembly without experience is fraught with the final failure of the device.
Official service vs. informal workshops: where is cheaper and more reliable?
Prices in authorized service centers Xiaomi (for example, Mi Service) start from 8000 rubles for the replacement of the screen with the original matrix.

- β οΈ Possible problems with color calibration after replacement
Compromise option β certified partners Xiaomi (not to be confused with official SC!) They work with original parts, but the prices are lower by 15-20%. For example, in Moscow, the replacement will cost 6500-7000 rubles against 8500 in Mi Service.

Step-by-step: how to replace the screen yourself
If you decide to repair yourself, prepare the following tools:
Suction cup (β 5-7 centimeter)|Plastic mediators (0.15-0.3 mm)|Screwdriver. T3 and T5 (magnetic)|Tweezers with curved ends|A hair dryer or a thermo-air station (t)=80-100Β°C)|Double-sided tape or glue B7000-->
The replacement process takes 1.5-2 hours. Follow the algorithm:

- Unscrew the 6 screws that hold the metal plate over the plumes. Unplug the connectors with tweezers.
- Remove the old matrix and clear the frame of the glue residue. Apply a new adhesive (e.g., B7000) to the new matrix.
- Connect the plumes to the new array, lock the plate and press the screen.

- ποΈ Broken Volume/Power buttons (replacement) +500-1200β½ They're easy to damage when they're disassembled.
To avoid unexpected expenses, before repairs, ask the master to conduct a full diagnosis (it is worth it). 300-500β½). It includes a check:
- Integrity of the motherboard (for microcracks)
- Operational capacity of all sensors (gyroscope, accelerometer, compass)
- Type-C connector states (often oxidized after moisture is ingested)
