Xiaomi Redmi Note 8 has a large display with a diagonal of 6.3 inches, which is the most vulnerable part of the device. Despite the use of durable glass Corning Gorilla Glass 5, the screen remains subject to scratches, chips and cracks when falling. Installing a quality protective glass is not just an aesthetic choice, but a necessary precaution to preserve the functionality of the gadget.
The process of sticking requires care, clean room and a certain sequence of actions. Mistakes at the initial stage can lead to bubbles, detachment of the edges or incorrect operation of the touch screen. In this article, we will discuss in detail how to avoid typical mistakes and achieve the perfect result the first time.
Owners of this model often face the problem of so-called "black bezels" or "rainbow effect" on the edges due to 2.5D screen rounding. The right accessory selection and installation technology allows you to minimize these visual defects. Get ready to work by preparing the workplace, as rush is not allowed here.
Choosing the right protective glass for the Redmi Note 8
The first and most important step is to buy the right accessory. The market is full of offers, but not all of them are perfect for the Redmi Note 8. The key factor is the type of coating: this model is best suited for glass with adhesive layers over the entire surface, not just along the outline.
Cheap options often have only a glue frame, which results in an air layer in the center of the screen, which not only impairs visual perception, but also reduces sensor sensitivity. A full-fledged adhesive layer provides a tight fit and preserves the brightness of the image.
Also worth paying attention to the hardness of the material. The optimal indicator is 9H, which guarantees resistance to scratches from keys and small debris in the pocket. Glass thickness should not exceed 0.33 mm, so as not to disrupt the fingerprint scanner and not increase the weight of the device.
- 🔍 Type of glue: Choose full-coated models (Full Glue) for better adhesion.
- 💎 Hardness: standard 9H Provides basic protection against abrasives.
- 📏 Thickness: 0.3 mm – the perfect balance between strength and tactile sensations.
⚠️ Warning: Avoid colored glass if you want to keep the original design of your smartphone.A black frame can overlap some of the useful image in games and apps.
Preparation of the workplace and necessary tools
The quality of the result depends on the conditions in which the sticker is made. Dust is the main enemy in this process, so the room must be pre-cleaned, ventilate and it is desirable to wipe all surfaces with a wet cloth to precipitate dust.
To work, you'll need a standard set, which usually comes complete with quality glass, but better prepare your proven tools.Switch on good lighting: a desk lamp should shine right at the workplace so you can see the smallest specks of dust.
Prepare everything you need to avoid distractions at a critical moment. Hands should be clean and fat-free, it is better to wash them with soap and dry them with a towel that does not leave villi.
☑️ Checklist of preparations
It is important to ensure the stability of the smartphone. If you do not have a special holder, use a soft substrate to prevent the device from sliding on the table during manipulation.
Step-by-step: how to glue glass without bubbles
Start by thoroughly cleaning the screen. Use a wet alcohol napkin (Wet) from the kit to remove greasy spots and fingerprints. Movements should be circular, without heavy pressure, covering the entire display area.
After wet cleaning, take a dry wipe and dry the screen. This is a critical step: any moisture residue will cause the glass to go unstick or swell. Check the surface at an angle in bright light.
The final step is to remove the microdust, use a sticky sticker (Dust Absorber) to apply it to different parts of the screen, if the dust is left, repeat the procedure, only after that you can remove the protective film from the glass.
⚠️ Warning: Do not touch the inner surface of the protective glass with your fingers after removing the protective film. The fat from the skin will break the adhesion and leave an indissoluble mark.
Carefully align the glass with the screen, focusing on the speaker and edges of the case. Xiaomi Redmi Note 8 has thin bezels, so positioning accuracy is important. Once you make sure all the holes match, smoothly lower the glass onto the screen.
Press the center of the screen with your finger. If the glass has a quality adhesive layer, it will start to crawl to the edges, pushing air out. Don't push hard on the edges until the center is fully grasped.

Comparison of protective coatings for Xiaomi
Not everyone knows that there are alternatives to classic tempered glass, depending on the operating conditions of the smartphone and the personal preferences of the owner. Below is a comparative table of the main characteristics.
| Type of protection | Impact protection | Tactile sensations | Difficulty of sticker |
|---|---|---|---|
| Tempered glass | High (blow extinguishes) | Perfect (like a screen) | Medium |
| Hydrogel (film) | Low (only scratches) | Good (soft) | High (stripes visible) |
| Ceramics | Medium (flexible) | Normal. | Low (forgives dust) |
For the Redmi Note 8, with its frequent use in navigation and instant messengers, classic glass remains the gold standard. It provides better protection when falling flat.
Hydrogel films are often chosen by those who use cases with poor compatibility, because they are thinner, but they will not save the screen from a serious impact on stone or asphalt.
💡
If you drop your phone a lot, buy glass labeled "Anti-Shock" or reinforced corners. They have a special shock-absorbing frame.
Problem Solving: Black Edges and the Rainbow Effect
One of the most common problems when installing glass on the Xiaomi Redmi Note 8 is the appearance of whitish or iridescent stripes around the perimeter.This is due to 2.5D technology, where the edges of the screen are rounded, and the glass simply cannot stick to the curved surface.
In some cases, this is solved by using a special glue-locker that is applied around the perimeter after the main cloth is installed. However, this requires high accuracy so that the liquid does not leak into the speaker or charging connector.
If you use a black-framed glass, the problem may be the bias, and the frame may overlap part of the matrix, creating a tunnel vision effect, in which case the glass is better replaced with a transparent or a model with a reduced frame.
- 🌈 Rainbow: arises due to the air layer on the rounds.
- ⚫ Black edges: the result of inconsistency of cutouts or poor quality of printing frames.
- 📉 Detachment: Often occurs if the cover presses on the edges of the glass.
Sometimes it helps to warm the edges with a hair dryer at a minimum temperature for 10-15 seconds, which makes the adhesive layer more elastic, but you need to be extremely careful not to damage the display matrix.
💡
Perfectly smooth sticker without a "rainbow" on 2.5D screens are possible only when using glasses with a reduced adhesive layer or a special UV-technology.
Protective care and frequent questions
After successful installation, it is important to properly care for the new layer of protection, and in the first 24 hours, it is recommended not to expose the smartphone to extreme loads and not to put it down on hard surfaces.
Rub the screen with a soft microfiber. Using aggressive chemicals or alcohol in its pure form on a regular basis can gradually destroy the oleophobic coating, making the screen dull and less pleasant to the touch.
If there's a bubble under the glass that doesn't disappear, try gently squeezing it from center to edge, and if there's a villi inside, you can try to remove it by slightly raising the edge of the glass with tape, but that's a risk.
