Broken glass or appeared stripes on the display of a smartphone is always an unpleasant surprise that knocks out. For owners of the popular model Xiaomi Redmi Note 8 the question of restoring the health of the device is especially acute, since this device is still actively used by millions of people around the world. The cost of replacing the screen is a key factor in the decision to repair the gadget or buy a new one.
In the current market, component prices can vary significantly depending on the region, the service chosen and, most importantly, the quality of the display module itself. It is important to understand that the original screen and the budget copy are two completely different things that affect not only the price, but also the comfort of using the smartphone as a whole. In this article, we will discuss pricing in detail so that you can make an informed decision.
Many users mistakenly believe that the cost of repairs is only the price of the parts, but the work of the master and the quality of adhesives also play a significant role. Poorly performed procedure can lead to dust falling under the glass or detachment of the matrix in the future.
Factors affecting the final cost of repairs
The final price is generated in a service center or a private master by several variables. The first and most obvious factor is the type of display module. In the Redmi Note 8 parts market, there is a clear division into original components (Original), high-quality copies (High Copy) and frankly cheap low-quality counterparts (OEM/Refurbished), the price difference between them can be as high as 200-300%.
The second important aspect is the complexity of the work being done: the screen in the Xiaomi Redmi Note 8 is glued around the perimeter of the body, which requires careful heating and the use of special tools for opening. If the glass is broken, but the image is displayed correctly and the sensor works, some wizards may offer a glass replacement (glazing), which is cheaper than replacing the module assembly, but requires complex equipment.
The price is also affected by the warranty and reputation of the service center. Official or authorized services often put a risk of defection in the price and provide a longer warranty than garage shops. In addition, the urgency of repairs can affect the final check: if a part needs to be ordered and wait a week, this is one, and if an express replacement is required from availability, the price can be higher.
Price comparison: Original vs. Copy
When making a decision to repair the user often faces a choice between the original display and its counterpart. the Original (Original) fully complies with the factory specifications of Xiaomi: it retains brightness, color reproduction, viewing angles and, critically, the operation of the sensor proximity and autobrightness. The cost of such a part will always be maximum, since it is purchased at the exchange rate from official distributors.
Copies (Copy/AAA/OEM) are divided into several classes. There are so-called "premium copies" that are visually almost indistinguishable from the original, but can have a slightly less bright backlight or a slightly different shade of white. Cheap copies often sin with poor oleophobic coating, low sensor sensitivity and no bezels around the display, which makes installation difficult. The cost of a copy can be as low as 40-50% of the price of the original, making them attractive but risky.
The price difference is also due to the production technology, and the original modules use high-quality technology. IPS-right-resolution matrix 2340×1080 (Full HD+). In cheap analogues, the resolution is often artificially interpolated, making the fonts look “loose”, and the pixel grid visible to the naked eye.
💡
Ask the wizard to turn on the screen before you install: check the multi-touch (swipe the icon across the screen) and the proximity sensor (close the top of the screen with your hand during the call).
Detailed price list for spare parts and work
To help you get your budget straight, we've put together an average price table, and it's worth considering that the cost can vary depending on the dollar and the region, and the table shows the prices for a full module (screen + frame + glass), because replacing only glass at home is almost impossible without the risk of damaging the matrix.
| Part Type / Service | Quality category | Approximate price (ruble) | Guarantee |
|---|---|---|---|
| Display module (Original) | The factory original | 3500 - 4500 | 12 months |
| Display module (High Copy) | Quality copy | 1800 - 2500 | 14-30 days |
| Display module (Economy) | Budgetary analogue | 1000 - 1500 | 14 days |
| Work of the master | Replacement of the module | 800 - 1500 | Work. |
The table shows that the savings on a cheap analog can be significant, but they come with risks. Cheap screens often have thicker glass, which may cause the smartphone to stop fitting into some cases designed for the exact dimensions of the original. In addition, the adhesive base on budget modules is often weak, which leads to gaps between the screen and the case over time.
And the cost of the work is worth mentioning, too. If you decide to buy a part yourself and bring it into service, many workshops may refuse a job guarantee or charge a higher risk rate. Usually, services charge a premium on the parts, but in this case they are fully responsible for the result. Buying the original on the marketplace in 90% of cases means buying a quality copy.
💡
The optimal choice for the ratio of price / quality for Redmi Note 8 often become high-quality copies (High Copy), which are visually almost not inferior to the original, but are much cheaper.
Technical nuances of replacing the display Redmi Note 8
The process of replacing the screen on Xiaomi Redmi Note 8 has its own features, which every owner should know. First, the back cover of the smartphone is glass and glued around the perimeter. To access the insides, you need to carefully warm the edges of the case and unplug the lid without damaging it and tearing the plume of the fingerprint scanner, which is often glued to the lid from the inside.
Second, the display module itself is also planted on glue. After the plumes are turned off, you need to warm up the front part evenly to soften the adhesive. Using metal blades without due care can lead to splitting of the new matrix or damage to the plastic frame. It is important to observe the temperature regime so as not to overheat the battery.
☑️ Checklist before the start of repairs
Another important point is calibration. After replacing the screen on some versions of MIUI firmware, it may be necessary to reset or recalibrate the sensor, although this is rare on the Redmi Note 8. The main problem that users face after unqualified replacement is a broken proximity sensor. This is often due to improper installation of the speaker's protective grid or shifting the plume.
⚠️ Attention: In self-disassembly, damage the main camera plume or fingerprint scanner, as they are located in the vicinity of the heating zone.
Can you save money: glass regression
There's a technique that can save money if only glass is broken and the image and sensor work perfectly, a process called OCA laminating, which involves carefully separating the broken glass from the matrix with a thin string (molybdenum thread) on a special heated machine.
After removing the fragments and cleaning the matrix from the old glue, new glass is glued onto it in a vacuum chamber, which eliminates the appearance of bubbles, a process that requires expensive equipment (separator, laminator, vacuum chamber) and a high level of skill of the master. At home, it is almost impossible to perform re-adhesives.
The cost of repainting is usually 30-40% lower than replacing the module assembly, but the risks are higher. If the matrix is splitting (which is often the case, especially if there were microcracks), the wizard will have to compensate for the cost of the new screen, so many services simply do not take this service for older models, preferring to change the module as a whole.
Why might the slack not fit your screen?
Typical problems after replacement and their solution
Even after a successful screen replacement, the user may encounter a number of software or hardware nuances, most often a situation where autobrightness does not work, this may be due to the fact that the light sensor is closed with a layer of glue or improperly installed in the seat, the solution lies in redisassembling and cleaning the area of the sensor.
Another common problem is fanatic taps, when the phone opens the apps itself, which is a sure sign of poor quality touchscreen in cheap copies, in which case only replacing the module with a better one can help, and sometimes there is an out-of-synchronization of the image when the picture floats or twitches, which is a sign of poor contact of the plume or defective controller.
After replacing the hardware, the smartphone can go into a cyclic bootloop, in which case it may be necessary to flash the device through the computer using the Mi Flash Tool utility and Fastboot mode. However, most often the problem lies in the physical compatibility of the installed spare part.
⚠️ Note: If the phone has stopped seeing after the screen has been replaced SIM-map, carefully check the antenna plume that may have been affected during installation.
