Finding the original display for the Xiaomi Redmi Note 7 smartphone has become a real quest for many users. Broken glass or the appearance of artifacts on the screen requires urgent intervention, but the market for spare parts is full of low-quality copies. The owner of the device faces a dilemma: save on a cheap counterpart or spend on a component that will return the phone to factory quality.
In this article, we will look in detail at where to look for original parts, how to distinguish them from fakes, and whether to change the entire display at all, learn about the intricacies of the Chinese component market and get proven strategies for finding reliable suppliers.
It is important to understand that the Redmi Note 7 has a IPS-resolution-matrix 1080x2340, It's hard to find an exact copy of the factory's color reproduction, and the wrong choice can lead to increased battery consumption or sensor problems.
We’ll look at all the sales channels available, from global platforms to local service centers, so you can make an informed decision. The quality of your smartphone build depends on which component you choose.
Features of the Redmi Note 7 matrix and display types
The screen in the Xiaomi Redmi Note 7 is one of the key elements that set the tone for the entire user experience.The factory matrix used by the manufacturer had excellent brightness and pixel density of 395 ppi. When searching for a replacement, you will come across three main types of screens, each of which has its own characteristics.
The first type is the original display, taken from broken phones or manufactured at Xiaomi’s supplier factory, which is fully specificated: viewing angles, color reproduction and sensor performance remain reference, but their market share is small, and the price often approaches the cost of a new device.
The second type is high-quality copies, which try to mimic the original, which may have similar resolution, but are often less bright and have thicker bezels, and the sensor layer in these copies may work less accurately, which is especially noticeable when typing or in games.
The third type is cheap, low-resolution, distorted color reproduction, and buying one is guaranteed to be frustrating, as the difference in quality is visible to the naked eye, often using simplified connectivity technology, which can cause unstable performance.
Below is a comparison table to help you understand the difference between screen types:
| Characteristics | Original | Quality copy | Cheap analogue |
|---|---|---|---|
| Permission | 1080x2340 | 1080x2340 (often interpolation) | 720x1520 or lower |
| Brightness | High (up to 450 nits) | Medium | Low, faint. |
| Sensor | Multi-touch 10 points | Multi-touch (possible delays) | Multi-touch often doesn't work. |
| Frames. | Thin, uniform | A little thicker than the original. | Visibly fat. |
⚠️ Warning: Some sellers label cheap copies as "Original Quality." Always check screen resolution through special apps after installation.
Popular sites for ordering components
Finding a reliable supplier is half the success. Global marketplaces offer a huge selection, but the risk of running into an unscrupulous seller is also high. Let's take a look at the main options where you can buy a display module.
AliExpress remains the most popular marketplace, where you can find both originals and copies. The key to success is the seller's rating and the availability of reviews with photos. Look for stores marked "Top Brand" or specializing in parts for Xiaomi.
Local electronics markets, such as the Gorbushka market in Moscow or similar radio markets in other cities, allow you to touch the product with your hands, but the price here will be much higher because of the markup of the dealers, the advantage is that you can visually assess the quality of the assembly before buying.
Specialist service centers often sell parts, but rarely agree to sell without replacement service, which is due to their warranty policy. If you find a SC ready to sell a module, this can be a great option.
There are also forums and repair communities where the repairmen sell parts, where you can find honest reviews about specific batches of screens, and verified contacts are often passed on by word of mouth.
When ordering from abroad, consider delivery times and possible customs duties. Logistics can take anywhere from two weeks to a month, which is important if the phone is needed urgently.
How to distinguish the original display from a fake
Visual diagnostics is the first step to understanding what you're holding. The original Xiaomi Redmi Note 7 screen has certain markers that are difficult to fake in artisanal settings.
Notice the quality of the print on the plume. The original text is clear, not blurred, and easy to read under a magnifying glass. Copies often have code errors or blurry characters. The encoding must be consistent with factory standards.
Check the thickness of the frames. The original module fits perfectly into the housing, without gaps or protrusions. Copies often have uneven fields, especially at the bottom where the plume is located. This can lead to assembly problems.
Color reproduction is another important indicator: the original produces deep black and saturated shades. Cheap matrices often have a bluish or yellowish hue that is noticeable on a white background. The brightness of the original adjusts smoothly, without jerking.
Use software testing methods. Install a screen test app and check all sensor areas. The multi-touch machine must work fault-free at all points.
Secret codes for screen checks
Remember the weight: the original framed module weighs a certain number of grams, and a light screen may indicate the use of cheap materials and the absence of protective layers.
Instructions for self-replacement of the display
If you're going to replace the screen yourself, prepare the workspace and the tools you need. You'll need a suction cup, a mediator (plastic blade), a hair dryer or heat heat heater, a set of screwdrivers and adhesives B-7000 or similar. Safety is above all, work carefully.
The first step is always to turn off the device. Then warm up the edges of the screen with a hairdryer to soften the glue. Be careful not to overheat the glass, otherwise it will burst even more, gently slap the glass with a mediator and walk around the perimeter.
After removing the rear window (in the Note 7 it is glass, be very careful!) or the screen, disable the battery plume. This is a critical step to prevent short circuit.
Next, unscrew the protective plate that covers the connectors of the display. Carefully unplug the old screen plume and install a new one. Check the phone until it's finally glued.
☑️ Checklist before changing the screen
If everything works, apply a new glue to the frame and press the screen. Use gums to fix it while drying. The polymerization time of the adhesive is usually 1 to 2 hours.
⚠️ Warning: Don't use superglue (cyanacrylate) to lock the screen! it emits fumes that can settle on the camera and sensors, disabling them.
Should I change the entire glass or the entire display?
Often users ask themselves, can you replace only broken glass, leaving the matrix? Technically, it's possible, but it requires special equipment. Separation (separation of glass and matrix) is done on a machine with heating and string.
At home, it's almost impossible to replace only glass without the risk of damaging the matrix. OCA-The cost of such equipment may exceed the price of a new display module.
In service centers, it costs less to replace the glass than the entire module, but the warranty is usually lower, and if the matrix is damaged when the glass is removed, the wizard will offer a replacement for the entire module.
If you have spots, stripes or dim areas on the screen, you only have to change the display unit assembled. Replacing the glass won't help here. The integrity of the matrix is a key decision-making factor.
The economic feasibility of replacing glass is high only if the matrix is in perfect condition, otherwise you risk losing money on a useless procedure.
💡
Replacing only glass makes sense only with the perfect work of the matrix and the availability of professional equipment.
Frequent problems after replacement and their solution
When you install a new screen, you can have unexpected situations, and one of the most common problems is that the proximity sensor is not working, and the phone may not be able to turn off the screen while you're talking, or it may be hanging.
The solution often lies in calibration. Go to the engineering menu (code ##6484##) and find the item "Proximity sensor." Plug a piece of tape on the top of the screen if the sensor is located there, or check the cleanness of the sensor area.
Another problem is the sensor's dead zones, which could be due to poor contact of the plume or defective parts, and try reconnecting the plume before you turn off the battery, and the density of the connector plays a big role.
If the screen is yellow or has uneven backlight, it is a sign of poor quality of the copy, you can return the product if you bought it on the site with a guarantee, otherwise you will have to accept or buy a new module.
Autobrightness issues are also common. check the settings in the Settings menu → Sometimes it helps to reset the settings to the factory, but it's a last resort.
