Broken glass or failed sensor on the popular Xiaomi Redmi 8 is a problem familiar to many owners of budget but reliable smartphones. When the screen stops responding to touch or is covered with a web of cracks, the user faces the question: should you carry the gadget into the service or try to save and do everything yourself? The cost of replacing the touchscreen consists of the cost of components and the complexity of work, which varies depending on the region and the chosen repair strategy.
In this article, we will discuss in detail the pricing policy of the Redmi 8 spare parts market, consider the difference between original parts and analogues, and assess the risks of self-interference in the design of the device. Understanding the real cost will help you make an informed decision and avoid unnecessary costs for poor-quality repairs or re-replacement of a failed module.
It's important to note that in modern smartphones, including the Redmi line, touchscreen is almost always soldered with a matrix (display) into a single unit, which means that replacing glass alone at home is impossible without specialized separation equipment, so in the calculations we will operate on the cost of a display module assembled, which is the standard for quality recovery.
Factors affecting the final repair price
The cost of repairing the Xiaomi Redmi 8 is not a fixed value and depends on many variables. The first and most significant factor is the quality of the spare part. There are original components labeled Original, high-quality copies (High Copy) and frankly cheap counterparts that can vary significantly in color reproduction and sensor sensitivity.
The second important aspect is the format of the service. You can purchase the part separately and try to install it yourself, which will require the purchase of tools and glue, or go to an authorized service center, where the price will include the guarantee and work of qualified engineers. Private craftsmen often offer an intermediate option, but it is important to consider their reputation and experience with adhesive foundations.
The price is also affected by urgency and location. In large metropolitan areas, the cost of renting space and the salary of masters is higher, which is reflected in the check. Also, if the smartphone is damaged not only the touchscreen, but also the frame of the case or the back cover, comprehensive repairs will cost more, although in some cases replacing the module with a frame can be even more profitable and easier to perform.
Price comparison: Original, copy and B/U spare parts
When searching for components for Redmi 8, you will come across three main price categories: original display modules made in Xiaomi or their official partners (such as Tianma or BOE) are the most expensive, they have perfect color calibration, the right oleophobic coating and full compliance with factory standards.
Quality replicas (often labeled OEM or High Copy) are 20-30% cheaper. Visually, they may be indistinguishable, but on closer inspection you can notice a less bright white color or a slightly less responsive touchscreen. Cheap counterparts can have problems with autobrightness and thicker frames, which is critical for a budget model where the bezels are not the thinnest.
And the second thing to consider is the market for B/U parts, and people often sell phones that have a broken body but a whole screen, and it can be a good idea to buy one if you can carefully rearrange components, but the risk of getting a part with burnt out pixels or micro-scratches on the sensor is high, making it a lottery.
| Type of spare part | Approximate price (ruble) | Image quality | Resource of work |
|---|---|---|---|
| Original (Original) | 2500 - 3500 | Reference | High-pitched |
| Copy (High Copy) | 1500 - 2200 | Good. | Medium. |
| Budgetary analogue | 900 - 1400 | Mediocre | Low. |
| B/U module | 1000 - 1800 | Depends on the condition. | Unknown. |
Why is the original more expensive?
Cost of services of service centers and private masters
If you don’t plan to do the repair yourself, you’ll have to budget for the cost of the work of specialists. In official Xiaomi service centers, the price for a replacement is composed of the cost of the original spare part and a fixed amount for the work. For the Redmi 8 model, the work can cost from 1000 to 2000 rubles, which, in total with the original screen, gives a tangible figure.
Private workshops and repair shops in shopping centers often offer more flexible prices, they can use both originals and copies of your choice, the cost of their services usually varies between 800-1500 rubles. However, it is important to clarify whether they guarantee the tightness of gluing, since factory moisture protection for artisanal repairs can not be restored.
There is also an option for on-site repairs when the master comes to you. This is convenient, but usually costs 500-1000 rubles more because of logistics. When choosing an artist, pay attention to the presence of an ultraviolet lamp for drying glue - this is a sign of a professional approach, not using cheap adhesive tapes.
⚠️ Attention: If the master offers to replace only the glass (top glass with a touchscreen) without replacing the matrix on the already assembled module in the conditions "on the knee" (without a separator), refuse this service.
Self-replacement: tools and costs
For those who are friendly with soldering iron and accuracy, self-replacement can be a way to save up to 50% of the market cost of repairs. However, you will need to purchase not only the display module itself, but also a toolkit. The minimum set includes a suction cup, mediators (plastic blades), a set of screwdrivers and a special glue B-7000 or E-8000.
The replacement process with the Redmi 8 is complicated by the fact that the back cover is glued around the perimeter, which must be carefully warmed up with a hairdryer and unstuck without damaging the fingerprint scanner, the plume of which can be glued to the lid. Sloppy movement can lead to a break in the plume, which will require additional repair and costs.
You also have to consider the risk of damage to other components, because if you do not open carefully, you can damage the plume of the main camera or charging module, so even when planning your own repair, you can budget for a small amount of money in case of unforeseen complications or purchase additional tools.
☑️ Replacement tools
💡
Before starting the disassembly, be sure to take a photo of the location of the plumes and screws. In budget smartphones, the screws can be of different lengths, and confusing them, you can damage the body of the motherboard.
Stages of replacement and technical nuances
The process of replacing the touchscreen on Xiaomi Redmi 8 requires consistency. SIM-Then, after heating up the back cover, we gently unplug it, and then we unscrew the screws that hold the plastic shield, which is hidden under the motherboard and the battery.
The key is to turn off the battery before any manipulation of the display plumes, so that the power controller will not short-circuit and fail, so that once the battery is turned off, you can gently disconnect the old display plume and remove it from the frame.
Installing a new module requires careful cleaning of the frame from the residue of old glue. The new module (often already in the frame) is installed in place, the plumes are connected, and a test switch is performed. Only after making sure that the touchscreen and image work, you can apply a new glue and fix the back cover.
⚠️ Warning: Never plug the new display plume into a hot one (without turning off the battery) is the most common reason the screen doesn't light up or doesn't work properly after being replaced due to a burnt-out backlight controller.
💡
The main difficulty of self-replacement is the careful removal of the back cover without damaging the fingerprint scanner and the subsequent high-quality sealing of the body.
How to check the quality of the installed touch screen
Once the work is done, whether in the service or at home, you need to conduct a diagnostic. Xiaomi smartphones have built-in engineering menu, available in code # # # #6484#. Select "Touchpanel" or "Display" to check the response of the sensor throughout the area.
Swipe your finger around the corners and center of the screen. There should be no dead zones where touch is not recorded, or phantom taps where the phone responds without you. Also check the multi-touch by clamping multiple dots at once - Redmi 8 supports up to 10 simultaneous touches.
Notice the brightness and color reproduction. Compare the white background to the reference image on another device. If the white color goes into yellow or blue, or if you notice "grain" (low resolution), then you have a substandard copy of the matrix.
