Xiaomi Redmi 8 Note smartphones have proven to be reliable devices with excellent autonomy, but their screens, made using IPS technology, remain vulnerable to mechanical damage. Even a slight fall on asphalt or an accidental impact on a hard object can lead to cracks or chips, replacing which will be expensive, which is why installing a quality protective glass is the first necessary procedure after buying a new gadget.
Many users are afraid to do this on their own, fearing air bubbles or dust getting under the glue layer. However, with a minimum set of tools and technology, you can stick the glass in a few minutes at home, getting a result that is not inferior to service. It is important to understand that the success of the operation depends on the quality of pre-treatment of the surface and environmental conditions.
In this article, we will go into detail the entire process, from the selection of consumables to the final polishing, and we will focus on the specific design of the Redmi 8 Note, including working with the proximity sensor and curved edges of the display, so that you can protect your phone in the most efficient and aesthetic way.
Selection of protective coating and preparation of the workplace
The first step to a successful installation is to choose the right tread. For the Xiaomi Redmi 8 Note, the market offers a variety of options, from cheap films to expensive glass with oleophobic coating and frames for full sticking. 3D-glass with a black frame, which completely covers the front panel, hiding possible irregularities of the factory assembly and providing protection of the entire area of the matrix.
It's critical to prepare the workspace, and dust is the biggest enemy when you stick it, so it's best to do it in the bathroom, where you've had humidification or wet cleaning done beforehand to precipitate flying particles, and you'll need bright lights to see the tiny villi on the screen, which can spoil the look after you've installed them.
⚠️ Warning: Do not start the procedure in a draft or near a running fan, air conditioner or open window.The air currents raise microscopic dust, which will inevitably settle on the adhesive layer at the most inopportune moment.
Be sure to prepare a clean, flat surface covered with soft cloth or towel so as not to scratch the smartphone body during operation. Make sure your hands are clean and dry, and your nails do not have barbs that could damage the adhesive layer or the screen itself when mounted.
Required tools and equipment
A standard safety glass set is usually sold with the accessory itself, but working with the Redmi 8 Note may require an extension of the base set.Ideally, you should have all the components at hand so as not to interrupt the process of finding missing items.
Below is a list of what needs to be ready for the start of work, and the absence of even one element can lead to the need to rework the work or put up with defects.
- 🧼 Wet and dry wipes (alcoholic and microfibre) for degreasing and polishing.
- 🌫️ Sticky tape (dust remover) for final removal of microparticles.
- 💳 Plastic card or rackel for purging bubbles (often included).
- 🔦 Powerful flashlight or table lamp for illuminating the screen at an angle.
- 🧵 Thin needle or pin (in case of complex dust bubbles).
Special attention should be paid to the alcohol napkin. If it is missing or looks dried, it is better to use medical alcohol and lilaless fabric. Fat spots from the fingers left on the screen before the sticker can lead to the appearance of "rainbow" spots under the glass, which cannot be removed without dismantling.
☑️ Checking sticker readiness
Detailed cleaning of the smartphone screen
The quality of the protective glass fit depends on how perfectly cleaned the surface of the display Xiaomi Redmi 8 Note. Even microscopic fat film, invisible to the eye, can cause detachment of the edges or the appearance of "lenses" of air.
Start with a wet wipe. Rub the screen in circular motions, paying special attention to the corners and areas around the speaker where skin fat often accumulates. After that, dry the screen with a dry wipe from the microfiber, removing all the divorces.
⚠️ Warning: Never blow on screen with your mouth to blow off a speck of dust! microscopic droplets of saliva that fly out when exhaled will settle on the surface and, after gluing the glass, turn into indissoluble greasy spots.
The final stage of preparation is to work with a sticky tape (dust remover), walk it through the entire display area, pressing and releasing it carefully to collect all the remaining villi, examine the screen at an angle in bright light: if you see a speck of dust, remove it with tape, only after that you can move to removing the protective film from the glass.
How to replace the sticky tape from the set?
Technology of the sticker: step-by-step instructions
The most important thing is the installation. For the Redmi 8 Note, which is quite large, it's important to position the glass correctly the first time. Most modern glass has a silicone adhesive layer that allows you to gently lift and correct the position if you don't pin them permanently.
Remove the bottom protective film (usually signed with the number 1 or labeled "Back") and, holding the glass behind the side edges, gently bring it to the screen. Combine the slots for the speaker and camera with the appropriate body elements. Once the glass touches the screen, it will start sticking on its own, spreading the adhesive layer from the center to the edges.
If the glass is crooked, don't panic. Carefully lift it around one of the corners (using a suction cup or nail if there is a gap) and adjust the position. Do this quickly until the adhesive layer has settled dust. After perfect positioning, slightly press the center to fix the glass, and remove the top protective film (number 2 or "Front").
Now, take a plastic card wrapped in a soft cloth (so you don't scratch the new glass), and start driving the air out. Move from center to edges with moderate effort. Pay special attention to the edges of Xiaomi, because because of the fact that you're not in the middle of the car. 2.5D-There may be air pockets in the air.
💡
The key to success is not to press the glass against the screen until it is fully aligned, and the silicone layer allows the glass to float on the surface, giving it time to correct itself.
Fixing defects: bubbles and dust
Even skilled craftsmen sometimes have small defects, and if you notice an air bubble, try pushing it to the nearest edge by pressing your finger through the fabric, and if the bubble doesn't go away, maybe there's dust under the glass.
To eliminate the speck of dust, you need a thin needle or tape. Gently lift the glass above the problem area (you can use the tape as a lever, gluing it to the edge of the glass and pulling it up), with a needle remove the villi from the screen or on the inside of the glass, then press it again. This requires jewelry accuracy and clean hands.
The table below shows common problems and ways to solve them:
| Problem. | Reason. | Decision |
|---|---|---|
| White rainbow spots | Fat or dirt on screen | Remove the glass, degrease the screen with alcohol, wipe dry. |
| No edges sticking. | Shape mismatch or dirt | Warm up with a hair dryer (carefully) or replace the glass with a smaller model |
| Grid (moir) on screen | Poor quality glass | Replace glass with a higher quality, oleophobic coating |
| Touchscreen doesn't work well. | The glass is too thick. | Use glass not more than 0.3 mm thick |
If you have small air bubbles left after all the manipulations, leave the phone for several hours under moderate pressure (for example, put under a heavy book, pre-wrapped in a towel), the adhesive layer will blur and fill the voids on its own.
💡
If the edges of the glass are constantly moving away due to wearing in the case, use a special case with a cutout under the screen or a case with a soft inner surface that does not press on the sidewalls of the glass.
