1.What kind of protective glass to choose for the Redmi 8 Pro
The first and most important step is to choose quality glass, and there are dozens of options on the market, but not all of them are suitable for the Redmi 8 Pro.
✅ Thickness: The best option is 0.33 mm, thinner glass (0.2 mm) is worse than the thick glass (0.5 mm).+) They can make the sensor less sensitive, except for oleophobic coating models, where the thickness can be slightly higher.
✅ Oleophobic coating is mandatory, without it, there will be fingerprints on the screen. Make sure the manufacturer indicates the presence of this layer.
✅ The kit should include the glass itself, a wipe for cleaning, an alcohol solution, a dust trapping sticker and a bubble-extracting map. If there is something missing, you better look for another option.
⚠️ Warning: Avoid glass with round edges (such as stainless glass) 2.5D or 3D), If you have a rigid frame on the body, these windows often don't stick around the perimeter, leaving gaps for dust.
- 🔹 Budget option: Spigen Glas.tR EZ Fit – good value for money, but requires careful installation.
- 🔹 Premium segment: Whitestone Dome Glass - self-setting glass with UV glue, but more expensive in the market 2-3 once.
- 🔹 The universal solution: Nillkin H+ Pro – suitable for most Xiaomi models with a diagonal 6.3-6.5 inch.
If you are not sure about the choice, check the reviews on AliExpress or Yandex.Market - there are often posted photos of the real installation on the Redmi 8 Pro. And do not forget to clarify that the glass should be compatible with the hole for the front camera (in this model it is located on the left at the top).
2.Tool preparation: what will be needed to replace
To replace the curtain without any problems, prepare everything you need in advance.
- 📱 New protective glass (compatible with Redmi 8 Pro)
- 🧴 Alcohol solution (isopropyl alcohol 70% or special liquid for cleaning screens)
- 🧻 Waxless wipes (microfibra)
- 🧲 Dust-capping sticker (usually complete with glass)
- 💳 Plastic card or special scraper for squeezing bubbles
- 🔦 Bright lamp or flashlight (to check for dust)
- 🧲 Magnetic screwdriver (if you plan to remove the frame of the case)
⚠️ Warning: Never use household alcohol or vodka to clean the screen! They contain impurities that can leave a divorce. Also avoid cotton-coat discs - they leave villi.
If you have old glass with cracks, you can remove it with a thin guitar mediator or a plastic blade. Don't use metal objects - they'll scratch the screen!
Before starting work, turn off the smartphone and remove SIM-This will prevent accidental button pressing and reduce the risk of static discharge.

3. Dismantling old protective glass: step-by-step process
Removing the old curtain is the most important step, and if the glass is really cracked, it can break into small pieces. Here's how to do it safely:
1. Put tape on the surface of the glass cross-over, which will prevent the fragments from breaking apart.
2. Put a plastic card or a mediator on the edge. Start at the corner where the glass has already broken off.
3. Slowly pull the scotch at an angle of 45.°, You're putting on the glass at the same time!
4 If the glass does not lend itself, moisten the edge with an alcohol solution - this will weaken the glue.
⚠️ Warning: If there are fragments left under the curtain, do not try to scrape them with a nail or metal. Use sticky tape (such as stationery tape) to carefully remove them.
Once the glass is removed, there's a sticky layer of glue on the screen, remove it with isopropyl alcohol and a lilac-free wipe, wipe the screen several times until it's perfectly clean, and swipe the screen with your finger to check, because if you hear the creak, you're not completely removed.
If you have traces of old glue on the screen that are not removed by alcohol, you can use a white spirit (very carefully!) or a special cleaner for smartphones. Under no circumstances use acetone or solvents - they will damage the oleophobic coating of the display.

4. Screen cleaning before installing new glass
Screen cleanliness is key to a successful installation, and even a tiny speck of dust can lead to bubbles or detachment.
1. Perform a wet cleaning: moisten the lilaless napkin with alcohol solution and wipe the screen in circular motions. Pay attention to the edges and areas around the front camera.
2 Remove moisture residue: use a dry microfiber napkin. Movements should be smooth, without pressure.
3. Check for dust: hold your smartphone to a bright light source at an angle. If you see particles, repeat cleaning.
4 Use a dust-removing sticker, which comes with glass, glue it onto the screen and remove it carefully, and it will remove even the smallest motifs.
Critically, don't touch the screen with your fingers after cleaning! Fat marks will worsen adhesion of the glue.
If the room is a lot of dust (for example, after repair), install in the bathroom after a hot shower - the steam will settle, and the number of suspended particles will decrease. Alternatively, use a lamp box (if you have access to such equipment).
| Cleaning error | Effects of consequences | How to avoid |
|---|---|---|
| Using Wet Napkins for Techniques | Divorces, deterioration of stickiness | Only lilac-free wipes. + alcohol |
| Cleaning in a dusty room | Bubble under glass | Close the windows, use the lamp. |
| Touching the screen after cleaning | Fat footprints, bad adhesion | Keep your smartphone out of the side |
| Using a dryer | Overheating of the display, damage OLED | Dry only naturally. |
5. Installation of a new protective glass: technique and nuances
Now, the most important step is the installation, and it's about fine-tuning and not rushing.
1. Remove the protective film from the inside of the glass (the one that is adjacent to the screen).
2. Line the glass across the front camera hole and the edges of the screen. Use the installation frame if it is included.
3. Carefully place the glass on the screen, starting at one end. Don't push it, it should fall under its own weight.
4. Squeeze the bubbles with a plastic map from the center to the edges. The movements should be smooth, without pressure.
If you have Whitestone Dome Glass, follow the manufacturer’s instructions: apply UV glue, install the glass, and fix it with an ultraviolet lamp (usually included).
⚠️ Warning: If you have small bubbles left around the edges, don't try to squeeze them out by force. Let the glass lie down for 24 hours, many of the bubbles will disappear by themselves. Large bubbles (more than 1 mm) indicate dust intrusion, in which case you have to reglue.
After installation, check the touchscreen sensitivity. Run any scroll application (e.g. Settings) → Apps) and make sure the sensor responds to touches all over the screen. If there are delays, maybe the glass is too thick or installed incorrectly.
💡
If your hands are shaking, use the water bath method: put your smartphone in a water bag (so that the screen is dry), and install the glass under water. Water will displace air, and there will be fewer bubbles. After installation, dry your smartphone with a dryer in cold mode.
6. Verification and final processing
But before you close the toolbox, you need to check the quality of the work.
- 🔍 Visual inspection: look at the screen from different angles. There should be no bubbles and iridescent divorces.
- 👆 Sensor test: pass the touch screen test in the engineering menu (code # #64663##).
- 💧 Hydrophobicity: Drop water on glass – it should roll without leaving traces.
- 📱 Case Compatibility: Put on a case and make sure the glass doesn’t cling to the edges.
If everything is fine, you can return it. SIM-The first day, try not to expose it to extreme stress (for example, do not play heavy games - this can cause overheating and detachment of the glue).
If 1-2 You notice that the glass is starting to move around the edges, which means that it's got dust or it's been applied unevenly, and then you have to do it again. You can use double-sided tape for the glass for reliability (sold in accessories stores), but it's a temporary solution.
Average service life of quality glass — 6-12 After that, the oleophobic coating is worn off, and the glass starts collecting fingerprints. If you notice that the screen has become sticky, it's time to think about replacing it.
💡
Even perfectly installed glass will not protect against strong impacts. If the smartphone often falls, consider the option with a bumper (hard frame) or a case with reinforced angles.

Even experienced users sometimes make mistakes when replacing the curtains, and here are the most common ones and ways to prevent them:
🔴 Bubble under glass:
The reason: dust, uneven gluing or too fast extrusion.
Solution: Use a dust-removing sticker and squeeze bubbles from the center to the edges.
🔴 Poor sensor sensitivity:
The reason: the glass is too thick or is installed with a skew.
Solution: Choose glass no more than 0.33 mm thick and check the alignment before sticking.
🔴 Rapid erasure of oleophobic coating:
Reason: use of aggressive detergents or frequent rubbing with alcohol.
Solution: Clean the screen only with microfiber dipped in distilled water.
🔴 Separation at the edges:
Cause: ingress of moisture or fat under the glass.
Solution: before installing, wipe the screen with alcohol and do not touch it with your fingers.
