Which Glass is Right for Your Xiaomi: 5 Choice Criteria
The first mistake most users make is to buy the first glass they find in the nearest store. For Xiaomi, this is especially critical because of the variety of designs: cutouts for the front camera, curved edges at the Mi 11 Ultra, ultrasonic fingerprint scanner from the front of the camera. POCO F4 GT. Universal glass will either not cover the entire screen or will block the sensors.
Here are the mandatory parameters that you need to pay attention to:
| Criteria | Why is it important? | An example for Xiaomi |
|---|---|---|
| Thickness | 0.15-0.33 mm - optimal balance between protection and sensitivity of touchscreen. Thicker 0.5 mm reduces responsiveness | For Redmi Note 10 Pro will fit 0.2 mm |
| Firmness | 9H — standard for scratch protection (7H–8H) fast-wash | All the glass for POCO X3 Pro go with 9H-covering |
| Oleophobic coating | Repels greasy finger marks, without it, glass gets dirty in an hour. | In budget windows for Redmi 9A often save on it |
| Under camera cut-out/sensors | Must match exactly with the location of the frontal and sensors | Mi. 12T Pro camera shifted to the left – universal glass will close it |
| Complementation | There should be wipes, dust collector, sticker for alignment | In the kits for POCO F5 often add an extra scraper |
Manufacturers that you can trust:
- 🏆 Spigen - premium glass with a guarantee for bubbles (there is a line of Glas.tR) EZ Fit for curved screens)
- 💎 Nillkin - optimal price/quality ratio, there are models with UV-self-installation
- 🛡️ AmFilm – specialize in Xiaomi, often update the range for new models
- 🔧 Original (in a phone box) – rare, but found complete with flagships
⚠️ Note: If your Xiaomi has a curved screen (such as the Mi 11 Lite or Black Shark 5), look for glass marked "Full Cover" or "3D Curved. -- Normal flat ones won't stick around the edges!

The most critical step is cleaning the screen, and even microscopic dust particles that are invisible to the eye will turn into bubbles after sticking, and service centers use laminators and vacuum cleaners for this, but you can do it at home with improvised means.
You'll need:
- 🧴 Alcohol wipes (70% isopropyl alcohol) – remove fat without dilution
- 🧹 Microfiber fabric (from a set of glasses or photo equipment) - for the final polishing
- 🧲 Scotch or paint tape – to remove the villi from the edges of the screen
- 💡 Bright lamp - illuminates the dust at an angle of 45°
Step-by-step cleaning:
- Turn off your phone and remove the cover, it may interfere.
- Wipe the screen with a wet alcohol napkin with movements from center to edges.
- Stick a piece of tape to the edges of the screen (where the frame) and sharply tear off - this will collect dust from the sides.
- Hold the phone to the lamp at an angle - if you see shiny dots, repeat the cleaning.
- Do not touch the screen with your fingers until the sticker is in place!
⚠️ Warning: Never use household chemicals (like Mr. Proper or Sanita)! It leaves a film that will keep the glass from sticking, only alcohol or special wipes for electronics.

Step-by-step: how to glue glass without bubbles
Now, the key secret is to align in the center, not the edges, if you start gluing from the corners, the glass will shift towards the end of the process, and we'll break down the dry sticker method (no liquids), because it's the most reliable for beginners.
Step 1. Checking the completeness
Take the glass out of the package and make sure it has:
- 📄 Instructions (even if you don’t read them, there may be a cutout scheme)
- 🧴 Wet and dry wipes (sometimes replaced by one double-sided wipe)
- 🧲 Dust collector (sticky tape for final cleaning)
- 📏 Positioning sticker (helps to align the glass)
Step 2. Placement of glass
Carefully apply the glass to the screen with the sticky side upwards (do not remove the protective film!).
- 🔍 The cutouts under the camera and the speaker coincide?
- 📏 The edges of the glass do not go beyond the screen?
- 🖥️ Touch buttons (if any) are not blocked?
If everything matches, put the glass aside.
Step 3. Sticker.
- Remove the top protective film from the glass (the one without glue).
- Carefully lift the glass at one edge, removing the lower film by 2-3 cm.
- Line the glass in the center of the screen (use the positioner sticker from the kit or make labels with scotch).
- Lower the glass on the screen, starting from the top, and gradually remove the protective film, pressing the glass against the display.
- Use a plastic scraper (or bank card) to drive the bubbles from the center to the edges.
Step 4 Final check
Turn on the phone and check:
- 🖱️ Touchscreen works in all areas?
- 🔊 The speaker is not muted?
- 📸 Front camera not obscured?
💡
If you have small bubbles left, put your phone under a heavy book for 12 to 24 hours, and most of them will disappear by distributing the glue.
Common Mistakes and How to Avoid Them
Even with a nice sticker, you can make mistakes that will ruin the result. TOP-5 problems and solutions:
| Problem. | Reason. | How to fix it |
|---|---|---|
| Bubbles around the edges | Dust or insufficient pressing | Hear the heat (not hot!) and press it with a scraper. |
| The glass is leaving in the corner | Poorly cleaned screen edge | Carefully slap and finish, using UV-glue (sold separately) |
| Rainbow divorces | Fat marks under the glass | Remove the glass, clean the screen with alcohol, glue again |
| Poor touchscreen sensitivity | Glass too thick (0.5 mm+) | Replace with glass 0.2-0.33 mm |
| The glass cracked on the sticker. | Strong pressure on the edges | Press only the center, the edges are fixed themselves |
Pay special attention to models with ultrasonic fingerprint scanner (for example, Xiaomi). 12T pro POCO F4 GT). If the glass is too thick or has a defect in the scanner area, the finger unlock will stop working".
⚠️ Warning: If the screen flickers or ripples after the sticker, the glass is pressing on the matrix!
What to do if the glass is crooked?
Features of the sticker on the Xiaomi model with curved screens
Xiaomi smartphones with curved displays (such as the Mi 11 Ultra, Black Shark 5 Pro or Mix Fold 2) require a special approach. 3D-Glass is harder to glue due to flexibility.
Here are the key differences for curved screens:
- 🔄 Use flexible glass (like Spigen Glas.tR or Whitestone Dome) that repeats the curve of the screen.
- 💧 Liquid glue is mandatory. A dry sticker won't keep the edges tight.
- 🔥 You need to warm the glass with a hair dryer (temperature 40-50)°C) for better fit.
- ⏳ Drying time increases to 24-48 hours (normal glasses take 2-4 hours).
For models with a retractable camera (such as the Mi Mix 3), choose a window with a hole under the mechanism. If you stick a solid glass, the camera can touch it when it is extended, which will lead to scratches or breakage of the mechanism.
Instructions for curved screens:
- Put it on. UV-glue on the screen in a thin layer (combined with Whitestone glass).
- Set the glass, aligned in the center, and press.
- Radiate. UV-lamp (365 nm) for 30-60 seconds for glue polymerization.
- Place the phone under the lamp for another 5-10 minutes for the final fixation.
💡
For curved screens Xiaomi suitable only glass marked "Full Cover" or "3D Curved Flat Glasses Will Fall Off in 1-2 Weeks.
How to remove old glass without damaging the screen
If you need to replace the glass (for example, it cracked or scratched), remove it carefully. Incorrect actions can leave microcracks on the screen or damage the oleophobic coating.
Method 1. Thread (for whole glasses)
- Stick the tape to one edge of the glass and pull up to form a gap.
- Put a denture or a thin line in the gap.
- Hold the thread at an angle of 45.° And then you cut it under the glass, gradually removing it.
Method 2: Suction (for broken glass)
- 🧲 Use a glass suction cup (sold in phone repair kits).
- 🔥 Heat the screen with a hair dryer (not higher than 60)°C!) - it'll soften the glue.
- 🖥️ Pull the suction cup up while putting the glass under a plastic spatula.
Method 3. Scotch (for small glass)
Stick a wide tape on the glass, smooth it out and sharply tear it off. Repeat 2-3 times, the glass will be removed with the tape.
⚠️ Warning: If you have sticky marks left on the screen after filming, remove them only with isopropyl alcohol! acetone, gasoline or solvents corrode the oleophobic coating of the display.
