How to stick a protective glass on Xiaomi Redmi: instructions with life hacks from masters

The security glass on Xiaomi Redmi is not a luxury, but a necessity: even a micro-crack on the screen can result in expensive repairs. But many users face the problem: after installing it on their own, bubbles, dust or it peels off after a day, the reason is not the quality of the glass, but the wrong sticking technique.

In this article, we will explore the unique techniques that professional craftsmen use in Xiaomi service centers: you will learn how to choose glass for a particular Redmi model (from Note 10 to Redmi 13C), what tools are really needed, and why alcohol solution and microfibre are only half the success, and also what to do if the glass is already glued crooked or dust accumulates under it.

What kind of security glass to choose for Xiaomi Redmi: 5 criteria

Not all glasses are equally useful. Cheap AliExpress options for 100 rubles can not only bad glue, but also reduce the sensitivity of the screen or leave rainbow divorces in bright light.

• 🔍 Thickness: Optimal - 0.2-0.33 mm Thin glass (0.15 mm) worse protect against impacts, thick (> 0.5 mm) reduces sensor responsiveness.
• 📏 Accuracy of the cutout: For the Redmi Note 12 Pro+ With a curved screen, it's only good. 3D-glass with flexible edges for flat screens (Redmi) 10A) — common 2.5D.
• 🛡️ Hardness: Minimum indicator — 9H (Mohs scale, labeled glass 9H+ or 10H longer resist scratching.
• 🧲 Oleophobic coating: High-quality glass repels greasy fingerprints. Check simply - swipe the surface with a dry finger: if there is a noticeable trace, the coating is weak.
• 📦 Set: The set should be alcohol wipes, dust collector (sticker), card for extruding bubbles and instructions with a pattern.

Among the brands tested are Spigen, Nillkin, Belkin and Xiaomi’s original Mi Protective Glass series. For high-frequency models (such as the Redmi K60 with 144 Hz), choose glasses marked “High Touch Sensitivity” – they do not reduce the response rate.

Preparation for installation: what to do before sticking

The mistake of 80 percent of users is that they start gluing glass onto a dirty screen, and even if you wipe the display with a microfiber, there are invisible fat traces and microparticles of dust on it, and it takes 10 to 15 minutes to prepare properly, but saves hours of gluing.

You'll need:

• 🧴 Isopropyl alcohol (70% and higher) or special wipes for electronics.
• 🧻 Wormless napkin (microfibre from a set of glass is not always clean enough).
• 💨 A compressed air canister (or a dust removal pear).
• 📏 Scotch (preferably paint) for fixing the pattern.
• 🔦 Bright lamp (such as a smartphone flashlight) to check the screen’s cleanliness.

Preparation process:

1. Turn off your smartphone and take out the SIM card (if the glass closes the tray).
2. Remove old glass or film. If it's glued heavily, use a plastic card to tamper with the edge (metal objects scratch the screen!).
3. Apply alcohol to the napkin and wipe the screen thoroughly, paying attention to the edges and areas around the front camera.
4. Blow the screen with compressed air at an angle of 45° to blow away dust from the speakers and slits.
5. Check the cleanliness: hold the lamp at an angle - if you see at least one motley, repeat cleaning.

💡

If you don’t have compressed air at hand, use a new toothbrush with hard bristles: carefully “mark out” the dust from the center of the screen to the edges.

Step-by-step: how to glue glass without bubbles

Now, the most important step is to follow the instructions in strict order, and even small things like humidity or the angle of glass affect the result.

Step 1: Verification of the conditions

• 🌡️ The temperature in the room should be 20-25°C. At low temperature, glue is worse, at high - too quickly.
• 💧 Humidity is not higher than 60%. In the bathroom or kitchen, you should not glue glass.
• 🪟 Close windows: draft can cause dust on the screen at the last minute.

Step 2. Applying glass

Combine the glass with the pattern from the set

Secure the pattern with tape so it does not move.

Remove the protective film from the glass only after fixing the position

Stick the glass from one end, avoiding distortions

Use the map to squeeze bubbles from the center to the edges-->

Details on each item:

1. Put the pattern (template) from the kit on the screen and fix it with paint tape on the sides, make sure that the camera holes and the speaker match.
2. Take the glass by the edges (without touching the glue side!) and remove the bottom protective film. If the package contains a dust collector (sticker), glue it to the screen before installing the glass.
3. Carefully place the glass on the screen, starting at the top edge. Don't push it, it should fall off itself under its own weight.
4. Use a plastic card or a special scraper to squeeze bubbles from the center to the edges.

Step 3. Finish check

Turn on your smartphone and check:

• 🔍 Are there any bubbles (especially around the edges).
• 📱 Screen sensitivity (take a test in Settings) → Display. → Touch test).
• 🎨 Color rendering (on some glasses, white can turn yellow).

Common Mistakes and How to Avoid Them

Even if you follow the instructions, users make mistakes that spoil the results.

⚠️ Note: If you are using Xiaomi Redmi with AMOLED-screen (e.g. Redmi) K70), Do not glue the glass immediately after a long period of operation of the smartphone. Let the screen cool for 10-15 minutes - overheating can cause uneven adherence.

How to remove dust and bubbles if the glass is already glued

If you notice defects after installation, do not rush to remove the glass. In 70% of cases, the problem can be fixed without gluing.

Bubble removal:

1. Take a plastic card or a bank card.
2. Carefully swipe from the center of the bubble to the edge of the glass. The movement should be unidirectional (not back and forth!).
3. If the bubble does not disappear, slightly heat the glass with a hairdryer (air temperature is not higher than 50 ° C) and repeat the procedure.

Dust removal:

• 🧹 If the motley is small and is located near the edge, try to gently tamper with the glass with a plastic card and blow the dust away with compressed air.
• 🔄 If the dust is in the center, you'll have to reglue the glass, heat it with a hair dryer (to soften the glue) and pull it around the corner.

⚠️ Warning: Never use a needle or knife to remove blisters, you will scratch the screen or glass. Also, do not press the blisters with your fingers: the fat from the skin will remain under the glass.

How much is a protective glass and when to change it

The life of the glass depends on the quality and intensity of the smartphone.

• 📅 Budget windows (9H, without oleophobic coatings – 3-6 months.
• 📅 Middle-class glass (9H+, with an oleophobic layer – 8-12 months.
• 📅 Premium glass (10H, with hydrophobic coating) - up to 1.5-2 years.

Signs that it is time to change the glass:

• 🔍 There are deep scratches that cling to the finger.
• 🖐️ Oleophobic coating is erased - the screen quickly gets dirty, fingerprints do not erase.
• 💥 On the glass with a shock-absorbing layer (for example, Spigen Neo Flex) appeared white spots – this means that the layer is worn out.
• 📵 The screen sensitivity has deteriorated (especially relevant for Redmi with the screen). 120/144 Hz).

If the glass is cracked but not broken, it can be kept in place until the cracks start to grow, but remember, the broken glass doesn't protect the screen, because when it hits, it can scratch the display.

💡

Even if the glass looks whole, change it once a year – over time, the glue loses its elasticity and the protection becomes less effective.

Alternatives to protective glass: when it is not necessary

The safety glass is not the only way to protect the screen, but in some cases, alternative solutions are sufficient:

• 🧻 Liquid glass (nano coating): Suitable for Xiaomi Redmi with curved screens (e.g. Redmi) K60 Ultra, where ordinary glass is not glued well, lasts 6-12 months, but does not protect against heavy impacts.
• 🛡️ Hybrid film: Thin (0.1 mm), but durable coated film 9H. It does not impair sensitivity, but it protects against falls.
• 📦 Bed cover: If you use a cover with a protruding edge (like the Spigen Tough Armor), it protects the screen when it falls on a flat surface.
• 🔄 Insurance: Some operators (such as MTS or Beeline) offer screen insurance. If you're a careful user, it may be more profitable than spending on glass.

But remember, no alternative offers 100% protection, like liquid glass not saving you from falling on the pavement, and film can break when it comes into contact with the keys in your pocket, and the best way to combine glass and a cover with a side.
