Xiaomi Redmi Note 8 Pro remains one of the most popular mid-range devices, and keeping its screen in perfect condition is a priority for the owner. Despite using Gorilla Glass 5's sturdy glass, the display is vulnerable to falls, keys in your pocket and accidental bumps against hard surfaces. A quality protective film or glass becomes the first barrier to take on mechanical load.
The process of installing protection often causes fear among users: it seems that there will be dust or curved edges under it. However, the sticker of the protective glass is not magic, but a clear algorithm of actions that requires attention and calmness. In this manual, we will analyze all the nuances of surface preparation, centering and final fixation, so that the result looks like factory.
Ignoring the rules of preparation can lead to the fact that expensive tempered glass will have to be thrown away, because it will not be possible to re-glue it without losing quality. Xiaomi has equipped this smartphone with a screen with a diagonal of 6.53 inches, which requires special attention to the edges and positioning accuracy. Let's prepare the workplace and get to work.
Choosing the right protective coating for the Redmi Note 8 Pro
The first step is not the sticker itself, but the right accessory. The market is full of offers, but for the Xiaomi Redmi Note 8 Pro, it is important to take into account the specific features of the display design. The screen of this device has a flat geometry, which greatly simplifies the task compared to the curved screens of flagships, but requires a precise match in size.
There are several basic types of protection, each with its own advantages and disadvantages: Hydrogel films are great at hiding small scratches and not breaking, but give less pleasant tactile sensations. Tempered glass provides maximum protection from impact and keeps the original display smooth.
When choosing, pay attention to the hardness of the material, which is usually labeled as 9H. This means resistance to scratches from metal objects, but does not guarantee indestructibility when falling on asphalt.
⚠️ Attention: Cheap glass without quality oleophobic coating quickly loses its properties, and the screen becomes rough and the finger slides worse.
An important parameter is transparency and the presence of a black bezels. For the Redmi Note 8 Pro, it is better to choose glass with a black edging that completely covers the edges of the display, hiding possible flaws when sticking and providing an aesthetic appearance.
Preparation of the workplace and necessary tools
The success of surgery depends 90 percent on the conditions in which it's performed. The main threat to a quality sticker is dust. Even a microscopic villi trapped under the glass will create a noticeable air bubble that will callouse your eyes. So choose a room where the draft is minimal and where wet cleaning has been done recently.
You'll need good lighting. A daylight lamp or a bright desk lamp will help you see the smallest bits of dust on the screen that will go unnoticed in dim light, and prepare a clean table surface that you should wipe with a wet wipe.
A standard safety glass delivery kit usually includes all the necessary tools, and check for the following items before starting work:
- 🧼 Alcohol napkin for degreasing the surface of the screen.
- 💨 Dry microfiber for polishing and removing villi.
- 🌫️ Sticky sticker (dust remover) for final cleaning.
- 🛡️ The protective glass or film itself.
If the kit does not contain a sticky sticker, it can be replaced with tape, but you need to act extremely carefully to avoid leaving adhesive marks. Some craftsmen also use a can of compressed air, but at home a carefully prepared dry wipe is enough.
☑️ Checking gluing readiness
Step-by-step: how to glue glass without bubbles
Now, the most critical step is to turn off your smartphone completely, or at least turn off the screen to see the contamination better, and scrub the display with a spirit napkin, removing all the greasy spots and fingerprints, and make sure that the movements are confident, covering the entire screen area.
After wet treatment, take a dry microfiber wipe and dry the screen. It's important to get the perfect clean, because any greasy trace under the glass will be visible as a rainbow spot. Then use a sticky sticker: apply it to different parts of the screen to collect settled dust.
Take the protective film off the inside of the glass. Do this carefully, holding the glass at the edges, and try not to touch the adhesive surface with your fingers. Bring the glass to the smartphone screen, focusing on the notches for the speaker and camera, as well as on the edges of the case.
| Phase | Action. | Important nuance |
|---|---|---|
| 1 | Degreasing | Use only an alcohol napkin |
| 2 | Dust removal | Apply a sticky sticker before the sticker itself |
| 3 | Positioning | Combining dynamic auditory dynamics |
| 4 | Fixation | Push from center to edge |
Once the glass touches the screen at one point (usually starting at the center or top), it will start sticking on its own thanks to the silicone layer. Don't press hard right away, let the air come out naturally. If the glass is crooked, you can gently lift it and correct it, but you need to do this until it's completely stuck.
💡
If the glass is crooked, don't try to move it by force. Gently lift the edge, correct the position and let it go again. Silicone layer allows you to do this several times until the glue dries.
Features of working with cutouts and sensors Xiaomi
Xiaomi Redmi Note 8 Pro features a front-facing camera built into the display as a small hole in the upper left corner.This requires high accuracy when installing the protective glass to match the hole perfectly.
The light and proximity sensor in this model is located in a thin bezel above the screen. If you use glass with a black opaque frame, make sure that the cutouts in the glass correspond to the location of the sensors. Otherwise, the phone may not turn off the screen during a conversation or adjust the brightness incorrectly.
For precise positioning, use the "example" method. Without removing the protective films from the glass, attach it to the phone turned off and look at the gap. Make sure that the black frame of the glass covers the edges of the matrix, but does not climb into the working area of the pixels.
⚠️ Warning: Never install a glass that override the proximity sensor.This will cause the screen to not go out during the bell and you will press the reset or hold with your cheek.
If you have a glass without a black frame (transparent at the edges), the task is simplified, since the risk of blocking the sensors is minimal, but in this case it is important to perfectly align the boundaries of the glass with the edges of the display to avoid visual imbalance.
What to do if the sensor is not working properly?
Removal of defects: bubbles, dust and villi
Even skilled craftsmen sometimes have defects when they stick, and the most common enemy is air bubbles, and if you notice an air pocket near the edge, try gently squeezing it out with your finger or a plastic card wrapped in a napkin, moving from center to edge.
A more complicated situation is when a speck of dust is hit by a glass, and it forms a characteristic bubble that doesn't disappear when pressed, and to fix this defect, you'll need a sticky tape (scotch) and a needle or blade.
Algorithm of actions when removing dust:
- 📍 Carefully lift the edge of the protective glass above the contamination site.
- 🧹 With the help of sticky tape, remove the villi with the adhesive surface of the glass or screen.
- 👇 Lower the glass again and smooth the place of gluing.
If you've got a fatty moiety under the glass, it's harder to remove it, you may need to re-paint it completely, and you may need to degrease it again, and in some cases, it helps to inject a drop of alcohol under the glass into the contamination site, but it's a risky method that requires caution.
Small air bubbles left in the center can disappear on their own within 24-48 hours, as the silicone layer continues to polymerize.
💡
The key to eliminating dust is to not panic and use sticky tape, and most large bubbles can be removed if you act quickly and carefully.
Drying and final inspection of the installation quality
Once the glass has taken its place, you need to give it time to grab it. Although primary adhesion is instantaneous, full fit and residual air output takes time. Leave the phone on a flat surface for 1-2 hours.
During drying, it is not recommended to actively use the sensor or put the phone in your pocket. It is best to put the device with a screen up under the table lamp (not too close so as not to overheat), which will speed up the process of polymerization of the adhesive layer.
After the time, do a visual inspection, check the corners, they should fit tightly to the screen, if the corners have moved away, this may indicate the presence of a case that presses on the edges of the glass, or the poor quality of the accessory itself.
Also check the touchscreen across the screen area. Swipe your finger from edge to edge while dragging the icon. There should be no dead zones or sticking. Quality glass does not affect the sensitivity of the Xiaomi Redmi Note 8 Pro.
