The protective glass on Xiaomi Redmi 8 is not just an accessory, but a necessary measure to keep the screen from scratches, chips and cracks. Even a slight fall of the smartphone can turn out to be expensive repairs if the display is not protected. However, many users face problems when installing: air bubbles, dust under the glass or improper positioning. In this article, we will understand how to avoid typical errors and achieve the perfect result the first time.
Redmi 8
6.22-inch IPS-screen
If you've never put a safety glass on before, don't worry, it's easier than it looks, patience and attention to detail, and for those of you who've tried it before, but have had a hard time, we're going to reveal the professional secrets that the service providers use.
Choosing a protective glass: what to look for
Not all glasses are equally useful. For Xiaomi Redmi 8, it is critical to choose an accessory that matches the model exactly.
🔹 Thickness: The optimal solution is 0.2-0.33 mm, too thin glass (0.15 mm) will quickly be scratched, and thick glass (0.5 mm) will be scratched quickly.+) impair sensor sensitivity and may interfere with the use of the cover.
🔹 Oleophobic coating is mandatory, it prevents finger divorces, ask the seller if it is on the selected model.
🔹 The kit should be:
- 🧴 Cleaning wipe (microfibra)
- 💧 Wet wipe (alcohol-containing)
- 🧲 Dust collector (sticker for removal of small particles)
- 📏 Positioning frame or template sticker
⚠️ Attention: Avoid glass with glass UV-They require a special lamp and experience, otherwise the glue will spread around the edges of the screen.
Producers that are trustworthy:
- 🏆 Spigen – premium quality, perfect fit under the camera cutout
- 💎 Nillkin - glass with enhanced strength (9H Mohs scale)
- 🛡️ Xiaomi Original – Official Accessories, but Check Compatibility with Redmi 8 (not to be confused with Redmi Note 8!)
Preparation of the smartphone: cleaning and degreasing
90 percent of the failures in glass installation are due to poor screen preparation, and dust, greasy traces, or residues of old glue will nullify all efforts.
1. Turn off the smartphone and remove SIM-This will prevent accidental touch of the screen while working.
2. Remove the old accessory (if you ever had one). Use a plastic spatula or a bank card by putting the glass in the corner. Do not use metal objects!
Clear the screen:
- Wipe with a wet alcohol napkin (from the kit) in circular movements from the center to the edges.
Remove the glue residues with a dry microfiber (without pressing!).
Walk the dust collector over the entire surface, especially around the edges and around the chamber notch.
⚠️ Warning: Do not use household detergents (soap, alcohol from the pharmacy) - they leave the film. Only isopropyl alcohol 70%+ ornamental.
Check the screen for microcracks, and if there are, the glass may not be leaky, so you'd better fix the display first.
💡
Before cleaning, wash your hands with soap and dry them. Fat marks from your fingers are the main cause of poor glass adhesion.
Step-by-step instructions for installing glass
Now, to the most critical stage, the important thing is to do all the manipulations in the room without drafts (dust with airflow is your enemy).
📌 Checklist before start:
☑️ Preparation for installation
🔧 Installation process:
- 📏 Positioning: Place the glass on the screen (without removing the protective film!) and check for matching cutouts. Use the frame from the kit or stick positioning stickers.
- 🧲 Dust removal: Walk through the dust collector again. Hold the screen up to the light at an angle, so you can see even microparticles.
- 🖼️ Removal of protective film: Carefully tuck the corner of the film on the glass and remove it with the glass behind the edges!
- 👆 Sticking: Apply the glass to the screen starting at the top (on the speaker side). With a light press in the center, spread it over the entire surface.
- 🧼 Blister removal: Use a plastic scraper (from the kit) or bank card to "push" air from the center to the edges.
⚠️ Warning: If there's hair or large moles left under the glass, don't try to move them! remove the glass and clean it again. Re-adhesion will worsen, but it's better than constant irritation from defects.
🎥 Video tip: If the glass "crawls" when you stick it, put it in a plastic card and move it gently. You have 10-15 seconds before the glue finally grasps.

Common Mistakes and How to Avoid Them
Even with careful preparation, you can make mistakes, and let's look at the most common ones and how to prevent them:
| Mistake. | Reason. | How to fix it |
|---|---|---|
| Bubbles around the edges | Incomplete removal of air or dust under glass | Warm up the edges with a hair dryer (30°C) and press it with a scraper. If it doesn't work, glue it. |
| Rainbow divorces | Fat or moisture on the adhesive layer | Remove the glass, clean the screen with alcohol and stick a new one. |
| The glass is coming out at the corners. | Poor adhesion due to old glue or glue curve | Use LOCA glue (only for the experienced!) or replace the glass. |
| Low sensor sensitivity | Glass too thick (0.5 mm+) | Choose glass thinner than 0.33 mm or with an ultra-thin coating. |
🔍 The secret from the masters: If the bubbles appear in a day or two, it is not a defect of the installation, but a natural drying of the glue. Wait 2-3 days - they will disappear on their own.
Critical error: using hair dryers instead of building hair dryers. Household hair dryer overheats the screen (Tmax = 60°C for Redmi 8), which can damage the matrix!
Checking the result and care for the glass
After installation, give the glass 24 hours to fully polymerize the adhesive.
- 🚿 Moisture infestations (do not wash your hands over your phone)
- 🌞 Direct sunlight (UV-radiation accelerates the drying of glue unevenly)
- 📦 Carrying in a pocket with keys/coins
How to check the quality of the installation:
1. Illuminate the flashlight at an angle - there should be no white spots (this is air).
2. Swipe your finger around the edges - they should be smooth, without burrs.
3. Test the sensor: run the keyboard and check the responsiveness of all zones.
🛠 Care behind glass:
Clean only with microfiber soaked in water or a special solution for optics.
Avoid ammonia products (such as Windex) – they destroy the oleophobic coating.
Change the glass every 6-12 months: over time, it loses strength and protection.
💡
The oleophobic coating is erased by frequent wipes with paper napkins. Use only microfiber!
Comparison of protective glass and film for Redmi 8
Many users are wondering which is better, glass or film? Let's take a look at the pros and cons of each option:
| Criteria | Protective glass | Protective film. |
|---|---|---|
| 🛡️ Level of protection | 9H (withstanding falls from 1 m) | 3H-4H (scratching only) |
| 🖱️ Tactile sensations | Like a bare screen. | Soft, "plastic" |
| 💰 Cost | 300–800 ₽ | 100–300 ₽ |
| 🔄 Term of service | 6–12 months | 3-6 months (quickly scratches) |
| 🎨 Appearance | Glossy as the original screen | Matte or glossy (choice limited) |
💡 When to choose a film:
You often change accessories and do not want to spend money.
You need a matte surface (less glare in the sun).
- You already have a case with high sides, which protects the screen from impacts.
For Redmi 8, we recommend glass – it better conveys the colors of the IPS-matrix and does not distort the picture when watching videos.
