Modern smartphones like the Xiaomi Redmi 8 come with quality-coated screens, but even the durable Gorilla Glass 5 isn’t immune to scratches or cracks when falling. The protective glass becomes the first line of defense, taking the brunt of mechanical stress. Proper installation of this accessory is not just an aesthetic procedure, but a necessary step to extend the life of your device.
Many users are afraid to take up this task on their own, fearing bubbles or dust beneath the surface. However, if you act carefully and follow a proven algorithm, the result will be as good as in the service center. In this article, we will discuss in detail the process of surface preparation and protection installation for the Redmi 8 model.
The success of surgery depends on 90% of how carefully you prepare the workplace and the device itself, and ignoring simple hygiene rules can leave a villi under expensive glass that can not be removed.
Preparation of the workplace and necessary tools
Before any electronic manipulations begin, you need to organize a space, and the ideal table would be a good lighting table, which does not have any extra junk, fuzzy fabrics or open containers of liquid, and dust is the main enemy when you stick glasses, so you better wipe the table with a damp cloth and let it dry.
Complete with quality safety glass for Redmi 8 usually comes a set to install.If you buy the accessory separately, make sure you have the following items on hand:
- 🧼 Wet wipe to remove fat and prints
- 💨 Dry microfiber to polish the screen
- 🌫️ Sticky sticker (dust remover) for final cleaning
- 📱 The most protective glass with adhesive layer
⚠️ Note: Do not use household chemicals containing ammonia or alcohol in high concentrations to clean the screen unless it is a specialized agent. Aggressive substances can damage the oleophobic coating of the matrix.
It is also important to turn off the smartphone before the procedure, the black screen of the device turned off best demonstrates the remaining dust and villi, and it will eliminate accidental pressing and heating of the gadget during operation.
Primary cleaning of the display surface
The most important step is to remove all contaminants from the display surface of the Xiaomi Redmi 8. Even microscopic fat particles can create a “lens” effect or prevent the glue layer from fitting tightly. Start by using a wet wipe from the set, carefully wiping the entire screen area in circular movements.
Pay special attention to the edges and the area around the speaker, which is where most of the skin fat and dust accumulate. After wet treatment, dry the screen with a dry wipe from microfiber. Movements should be confident, but without strong pressure.
If you have any stains on the screen, repeat the procedure. Surface cleanliness is critical, because the adhesive layer on the protective glass is disposable. If you glue the glass onto the dirt, you can't tear it off and reglue it without losing its sticky properties.
💡
If you can hear a creak ("clean glass creak"), you can see that the surface is defatted well. If the finger slides silently, repeat the cleaning.
Removal of microdust particles (Final stage)
After the main wipe, there are always microscopic villi from the napkin itself or dust that has settled out of the air. Use a special sticky sticker (dust remover) that comes with it. If you don't have one, you can use a piece of wide tape, but you need to be extremely careful.
Put the sticker up to the screen and just tap the whole surface with a little touch, and don't rub it, but put it down and remove it, and it's best done in side light, so you can see the reflection of every speck of dust on the black background of the display that's off.
| Type of pollution | Deletion tool | Risks of ignoring |
|---|---|---|
| Fat spots. | Wet wipe. | Rainbow divorces, poor grip |
| Village tissue | Dry microfiber | Air pockets |
| Microscopic dust | Sticky sticker | Black dots under glass |
| Static electricity | Antistatic (optional) | Attracting new dust |
Once you use the sticker, look at the screen from different angles again, and at this point, any speck you find can ruin the result. If you notice dust only after the glass is pasted, there are methods to remove it, but it is better to prevent it from appearing in advance.
☑️ Sticker-ready
Technology of adhesive protective glass
When the surface is perfectly clean, you pick up the protective glass itself. It's important not to touch the inner adhesive surface with your fingers. Most Redmi 8 glasses have a protective film labeled (often "1" or "Back") that you need to remove before installation.
Carefully hold the glass to your smartphone, focusing on the notches for the speaker and the front camera. Redmi 8 camera is located in the upper left corner, and the speaker is in the upper center, combine these elements with maximum accuracy before the glass touches the screen.
Once you've made sure that the positioning is correct, you can gently lower the glass onto the display, and because of the properties of the silicone glue, it will stick itself from the center to the edges, a process called self-leveling. Don't push hard in the center, let the glue spread naturally.
⚠️ Warning: If you see a glass that has gone crooked, don't try to move it by force after full contact. This can damage the adhesive layer. Raise the edge slightly and adjust the position before the adhesive wave goes.
Once the glass is fully on the screen, take a dry wipe and move lightly from the center to the edges to smooth the surface, expelling possible residues of air. Pay special attention to the edges, as on the Redmi 8 they can be slightly rounded (2.5D), and there the air is retained most often.
What to do if the glass is not glued to the edges?
Fixing defects: bubbles and dust
Even skilled craftsmen sometimes have defects, the most common being an air bubble. If it's small and it's near the edge, just squeeze it out with your finger or a dry wipe towards the open end. The big bubbles in the center are often not air, but dust.
If there is dust under the glass, you can try to remove it in the following way:
- 📌 Carefully lift the edge of the protective glass above the problem area with a thin needle or tape.
- 🌬️ Use a sticky sticker to “pull” a morsel off the glue layer of glass or from the screen.
- 🔄 Again, smooth the glass from the center to the edge, removing air.
Sometimes the bubble can be caused by a factory defect in the glass itself (curvature), which is not enough to drive it out, and small bubbles can disappear by themselves through the glass. 24-48 hours as the adhesive layer continues to polymerize.
💡
Small bubbles, similar to ripples, often disappear on their own within a day. Do not touch them aggressively, so as not to damage the structure of the glue.
Polishing and final inspection
Once installed successfully, remove fingerprints that were inevitably left on the outside during installation. Rub the surface with a dry microfiber until it shines perfectly. Make sure the sensor responds to touches across the entire area, including the edges.
Check the front camera and speaker. The speaker grid on the Xiaomi Redmi 8 is quite large, and if the glass does not have special cutouts or acoustic channels, the sound may become quieter or there is an “echo” effect.
If you use a case, put it on and make sure it doesn't press on the edges of the glass. The pressure of the case can lead to perimeter detachment over time. The quality glass must be case-friendly compatible with most cases.
