How to put a protective glass on Xiaomi without bubbles: a complete guide with video and expert advice

The protective glass on Xiaomi’s smartphone is not a luxury, but a necessity: it prevents scratches, chips and cracks in the screen when falling. 3D-It's going to lose its properties if you stick it in a curve, with bubbles or dust underneath the surface, and service centers charge you 300 to 1,000 rubles for this procedure, but you can actually do it at home, if you know the exact sequence of actions and the secrets of the masters.

The main problem with self-sticker is microbubbles that appear due to dust, improper pressure or poor screen preparation. In this article, we will analyze not only the standard instructions, but also the unique techniques that repairmen use (for example, the method of “wet installation” or how to expel bubbles without disassembling the phone). You will also learn which Xiaomi models require a special approach due to the curved edges of the screen (Mi 11 Ultra, Redmi Note 12 Pro).+), Why cheap AliExpress windows often fall off after a week.

Before you start, check: you should have not only the glass and wipes on hand, but also a special glue spray (for example, you should have a special glue spray, LOCA), UV-A lamp (for polymerization), and even -- a regular credit card. Yeah, it's useful! And if you've never glued glass before, don't worry: at the end of this article, there's a step-by-step video guide on Xiaomi. 13T Pro.

1. Which security glass to choose for Xiaomi: comparison of types and brands

Not all glasses are equally useful, cheap 100 roubles "nonaim" options can not only protect poorly, but also depress the sensitivity of the screen or peel off after a couple of days.

• 🔹 Thickness: optimally - 0.2-0.33 mm Thin glass (0.15 mm) worse protect against impacts, and thick (> 0.5 mm) may interfere with the fingerprint scanner.
• 🔹 Type of coating: Oleophobic (repels fat) or Hydrophobic (repels water.
• 🔹 Edges: for Xiaomi with curved displays (Mi 11, 12S Ultra) take it 3D-rounded-glass.
• 🔹 Manufacturer: proven brands - Spigen, Whitestone Dome, Belkin, Nillkin. for budget models (Redmi) 10C) ArmorSuit is fine.

Note compatibility with the fingerprint scanner. For example, on the Xiaomi 13 Pro, cheap windows often block the sensor — you have to remove the protection to unlock the phone. If in doubt, check the reviews on Yandex.Market or Wildberries by the filter “compatible with [your model]”.

2.Preparation of the phone: how to clean the screen of dust and fat

90 percent of the bubbles are caused by microparticles of dust or grease that are left on the screen, and even if you think the display is clean, you'll see a zoo of pollution under the microscope.

1. Turn off your phone and pull out your SIM card (if it interferes), and you can't use the screen on, it draws dust with static electricity.
2. Use a scotch Velcro (complete with glass) glue it to the screen and rip it off abruptly, it will remove the large particles.
3. Wipe the screen with an alcohol napkin (at least 70% isopropyl alcohol) and move from center to edge without pressing hard.
4. Blow the screen with compressed air (such as a keyboard cleaner). The alternative is to use a vacuum cleaner at a minimum power (keep it at a distance of 5 cm!).

⚠️ Warning: Never use wet hand wipes, glass liquid or gasoline to clean – they leave a film that will keep the glass from sticking.

Sticker methods: dry vs. wet installation

There are two main ways to stick glass: dry (classic) and wet (using liquid). The first is simpler, but only suitable for flat screens. The second is more difficult, but guarantees a perfect fit even on curved displays.

Dry editing is suitable for most users. The algorithm is simple:

1. Remove the protective film from the glass (only on one side!).
2. Carefully apply the glass to the screen, starting from the top.
3. Use a credit card or a special scraper to kick bubbles from the center to the edges.

Wet installation (with glue) LOCA) It takes a lot of skill, but it gives you the perfect result:

1. Apply 2-3 drops of glue on the screen and distribute them with a credit card.
2. Attach the glass and fix it with special clips (go with the set Whitestone Dome).
3. Light up. UV-lamp 30-60 seconds for polymerization of glue.

4. Step-by-step instruction: how to glue glass without bubbles

Now, the most important thing is the sticker, and you follow this algorithm, and you get the perfect result, even the first time.

Step 1. Centering the glass

Before you take off the protective film, apply the glass to the screen and check if the notches for the speaker and the camera match. Most of the Xiaomi glasses have special tags — focus on them. If the glass is walking, use paint tape to fix its position.

Step 2. Sticking

Take the protective film with the adhesive side of the glass (only on one edge!) Carefully apply the glass to the screen, starting at the top, and gradually lower it down. Don't push hard, let it lie down under its weight.

Step 3: Bubble removal

Take a credit card or a plastic scraper (it comes with it) and move softly from the center to the edges, "push out" all the bubbles. If some bubble doesn't go away, lift the glass slightly and press it again.

💡

If the bubble appears under the speaker or camera, don't try to squeeze it out, it can damage the modules. Instead, gently tuck the glass in that spot and glue it back.

Step 4: Fixing

After the sticker, don't turn on your phone for at least 2 hours, the glue should freeze. LOCA, 10-15 minutes is enough. UV-Don't press the screen or put on a cover at this time!

💡

The most common mistake is to try to smooth bubbles with your fingers, which only makes things worse, because there's fat on your skin that interferes with the clutch. Use only a plastic scraper or a credit card!

5. What if bubbles do appear?

Even professionals sometimes have microbubbles, and here's how to deal with them:

• 🔄 Small blisters (up to 1 mm): usually disappear after 1-2 days, when the glue finally dries.
• 🔄 Middle bubbles (1-3 mm): Try to gently “eject” them with a scraper, starting from the nearest edge.
• 🔄 Big bubbles (> 3 mm) or clusters: you have to glue the glass, you can pull it from the edge and repeat the process.
• 🔄 Bubbles under the speaker/camera: if they don't interfere with the sensors, you can leave them.

⚠️ Warning: If the bubbles appear a week after the sticker is a sign of poor-quality glue, it is better to remove and replace it with a new one, otherwise it will fall off on the first fall.

If you do not want to glue the glass, you can try the method with soap solution:

1. Mix the water with a drop of liquid soap.
2. Apply the solution under the glass with a syringe (neatly lifting the edge).
3. Smooth the bubbles with a scraper and let dry for 12 hours.

This method works in 60% of cases, but there is no guarantee - it all depends on the type of glue on your glass.

6. Features of the sticker on popular Xiaomi models

Not all Xiaomi smartphones are the same. Here's what to consider when sticking glass on different models:

On Xiaomi 13 Ultra and other flagships with ultrasonic fingerprint scanner (in screen), it is important that the glass is as thin as possible (0.2 mm or less). Otherwise, the sensor will not recognize fingerprints. Before buying, check in the description compatibility with "ultrasonic fingerprint".

For POCO-series, for example, POCO X6 Pros are often the same line of Redmi glass, they have identical screens, but be careful with the cutouts for the front camera!

7. Frequent mistakes and how to avoid them

Even a small mistake can ruin the whole thing. TOP-5 Beginners’ mistakes and how to prevent them:

• 🚫 Sticker on the phone turned on → The screen heats up and attracts dust. Always turn off your smartphone!
• 🚫 Use of household detergents → They leave the divorces. Only isopropyl alcohol 70%+.
• 🚫 Finger pressure on glass → There are greasy marks left. Use a plastic scraper.
• 🚫 Sticker in a dusty room → It is ideal to do this in the bathroom after shower (humid air binds dust).
• 🚫 Ignoring bubbles "for later" → They won't disappear in a day, but the glue will harden!

Another common problem is that the glass moves away from the edges after a week, and it's because of:

• 🔹 Cheap glue (especially in glass with AliExpress for 50 rubles).
• 🔹 Incomplete removal of fat from the screen before the sticker.
• 🔹 Using the phone in the case immediately after the sticker (the case presses on the edges).

If the glass has started to flake off, you can try gluing it with Moment Gel superglue (point, edge), but this is a temporary solution. Better re-glue it with quality glass.

8.Security glass alternatives: when it is not suitable

Safety glass is not a panacea, and in some cases, it is better to consider alternatives:

• 📱 Hydrophobic film: thinner than glass (0.1 mm), does not affect the fingerprint scanner, but worse protects against impacts.
• 📱 Liquid glass (nano coating): applied as a varnish, imperceptibly on the screen, but lasts only 3-6 months. Good for temporary protection.
• 📱 Kevlar coating: stronger than glass, but more expensive and difficult to apply, used in military versions of smartphones.
• 📱 Case with a ledge: if you do not want to glue anything on the screen, take a case with high sides (for example, Spigen Tough Armor).

On foldable smartphones (Xiaomi Mix Fold 3, Mix Flip) glass glue is not recommended — it will interfere with the mechanism, the best option is a flexible film or liquid glass.

If you drop your phone frequently, consider a combined protection: glass. + durable cover (e.g, UAG This will increase the chances of surviving a fall from a height of 1-1.5 meters without damage.
