What kind of security glass to choose for Xiaomi Redmi Note
The market offers hundreds of glass options, but not all of them are equally good.
- 🔍 Thickness: optimally - 0.2-0.33 mm Thin glass (0.15 mm) worse protect against impacts, thick (> 0.5 mm) may impair screen sensitivity.
- 📏 Cutout accuracy: for the Redmi Note 10/11/12/13 Universal glass with a cutout for the front camera, but for Note 9 Pro with a centered hole for a selfie camera you need to look for specialized.
- 💎 Hardness: minimum — 9H (Mohs scale. 8H scratch.
- 🔄 Oleophobic coating: should be applied evenly. Check reviews - if after a month the glass "sticks" from the fingers, it is a marriage.
Brands that are trustworthy:
- 🏆 Spigen – premium quality, but expensive (from 800) ₽). It is suitable for the Redmi Note 12 Pro.+ curved.
- 💰 Nillkin – optimal price/quality ratio (300–500) ₽). There are options with UV-glue for perfect fit.
- 🛡️ AmFilm – Budget segment (200-350) ₽), But you get fakes a lot.
⚠️ Warning: Glass with a “self-healing” coating (such as Whitestone Dome) requires UV-Without it, the glue won't harden, and the glass will fall off in a day.
Preparation of the smartphone: what to do before installation
80 percent of users fail to clean the screen properly, and even invisible dust particles or greasy finger marks cause bubbles, and it takes longer to prepare than the sticker itself, but it's a critical step.
- Turn off your smartphone and remove the SIM card/memory card. Vibration at notifications can shift the glass during installation.
- Wipe the screen with a wet wipe (no alcohol!) and microfiber glasses or special iCloth wipes will do.
- Remove old glue (if any). Use 90%+ isopropyl alcohol or 3M sticker removal. Don't use acetone - it corrodes the oleophobic screen covering!
- Blow the screen with compressed air (a tank for cleaning equipment). The alternative is Scotch: glue it to the screen and sharply tear it off 2-3 times to collect microparticles.
🔍 Dust check: point bright light at an angle on the screen. If you see particles, repeat cleaning. Pay special attention to the edges and areas around the speaker / camera.

Step-by-step: how to glue glass without bubbles
Now, to the most critical stage, you're going to need to:
- 📱 Protective glass (with film substrate and a positioning sticker).
- 🪛 Plastic spatula or credit card for smoothing.
- 💡 Bright light source (desktop lamp or flashlight).
- 🧴 A drop of soap solution (optional, to adjust the position).
Step 1. Positioning the glass
Take the transport film off the glass, but don't remove the bottom substrate! Carefully apply the glass to the screen, combining the cutouts for the camera and the speaker. Most of the glass has a silicone frame-hint to help align the glass around the edges. On the Redmi Note 10/11 models with a centered camera, make sure that the hole is strictly in the center.
Step 2. Fixing.
When the glass is perfectly flat, lift it by one edge and remove the bottom substrate. Slowly lower the glass onto the screen, starting at the top. If it's gone, don't panic: you have 10 to 15 seconds to correct it. To do this, drop the soap solution under the edge and move the glass with a spatula.
Step 3. Smoothing
Take a plastic blade and move the bubbles out of the air in a smooth way from center to edge. Press moderately — if you overdo it, the glue can leak and the glass will rise. Check the result under light: small bubbles (up to 1 mm) usually disappear after 12 to 24 hours.
💡
If the bubble is left under the speaker or camera, do not try to squeeze it out - this can damage the modules.
| Mistake. | Reason. | How to fix it |
|---|---|---|
| Bubbles around the edges | Poor cleaning or uneven pressure | Re-glue the glass, paying attention to the edges |
| The glass leaves in a day. | Cheap glue or greasy screen | Use alcohol for degreasing, choose glass with UV-glue |
| Rainbow divorces | Low-quality oleophobic coating | Replace the glass (unrepairable) |
| Poor touch sensitivity | Glass too thick (> 0.5 mm) | Choose glass thinner than 0.33 mm |
Features of installation on the model with a curved screen (Redmi Note 11 Pro +, Note 12 Pro +)
Smartphones with 2.5D or 3D-screens (for example, Redmi Note 11 Pro)+ Or the Note 12 Turbo, which requires a special approach, and standard glass doesn't cover the edges completely, leaving vulnerable areas:
- 🔹 Full coverage glass has flexible edges that bend to the ends, minus is harder to glue, and over time, the edges may detach.
- 🔹 UV-Glass (like Whitestone Dome) hardens under an ultraviolet lamp, repeating the curves of the screen. Requires precise installation - a mistake of even 1 mm will lead to detachment.
- 🔹 Hybrid variant: ordinary glass + It's a flexible film on the edges, cheaper, but less reliable.
⚠️ Attention: Redmi Note 11 Pro+ Full-coated glass can block the proximity sensor. Before buying, check if there are any sensor pads in the kit.
Installation process UV-glass:
- Apply the liquid glue on the screen (comes complete).
- Place the glass and align it with the marks.
- Radiate. UV-lamp for 20-30 seconds (keep at a distance of 2-3 cm).
- Remove the excess glue with a napkin.
What happens if you don't use it? UV-lamp?
What to do if the glass is unstuck or bubbles appear
Even with a perfect installation, problems can occur over time, and let's look at the typical cases and how to fix them:
- 🌀 Small bubbles: usually disappear in 24 to 48 hours. If not, gently prick with a needle and smooth with a spatula.
- 🪟 The edges move away: dent the detached area and apply a drop of cyanoacrylate glue (superglue). Press for 10-15 minutes with a load (for example, a book).
- 🚫 The glass is cracked, only replaced, even small cracks will eventually disperse, and the fragments can scratch the screen.
- 👆 Poor sensitivity: check if the glue is under the touch gauge. If so, the glass needs to be re-adhesive.
💡 Tip: If the glass is unstuck after 1-2 weeks, it is likely a problem as adhesive. For a temporary solution, you can use double-sided tape for screens (sold in electronics stores), but this is not a long-term solution.
For models Redmi Note 8/9 with flat screens suitable method of "wet" installation:
- Moisten the screen with soap solution (1 drop of liquid soap per 50 ml of water).
- Place the glass and level it.
- Squeeze the water with a spatula from the center to the edges.
- Dry with a hair dryer for 2-3 minutes at minimum power.
💡
If the glass has been unstuck by moisture (for example, after showering), do not try to glue it back. The glue has already lost its properties - you need to install a new glass.
How to extend the life of the protective glass
Even the most expensive glass will not last long, if you do not follow the simple rules:
- 🧴 Cleaning: Use alcohol wipes 1 time per week. Do not use abrasives!
- 📱 Case: Choose high-sided models (like the Spigen Tough Armor) to protect the edges of glass when falling.
- 🔥 Temperature: Don't leave your smartphone in the sun or near heaters.Adhesive loses its properties when heated above 50°C.
- 💧 Moisture: When you get water, dry the screen immediately. Humidity speeds up the detachment.
📊 Life of glass depending on care:
| Conditions | Term of service |
|---|---|
| Perfect care (cleaning, cover, no falls) | 12–18 months |
| Medium care (periodic cleaning, rare falls) | 6–12 months |
| Aggressive exploitation (frequent falls, no cover) | 1-3 months |
⚠️ Warning: If there are microcracks on the glass (even invisible ones), it needs to be replaced, and they weaken the structure, and the next impact the glass will split, and the fragments can scratch the original screen.
