Bubbles on Xiaomi screen: why appear and how to remove without a trace

Why are there bubbles on Xiaomi’s screen – and should you panic?

You see strange air bubbles under the glass or protective film on Xiaomi? Don't rush your phone to the service center -- 80 percent of the time, you can solve the problem yourself without spending money on replacing the display. Bubbles arise for all kinds of reasons, from poor-quality gluing of glass to factory defects of the glue layer. But most often, users who save on accessories or violate the installation technology are to blame.

In this article, we will analyze all possible causes of bubbles on Xiaomi screens (including the Redmi Note 12 models, POCO X5, Mi 11 and others), and give step-by-step instructions for their elimination - from simple methods with improvised means to radical measures.

Spoiler: If the bubbles appeared under the original glass that came with the phone, the chances of successful removal are minimal, and only re-painting will help. But if it's a protective film or a third-party glass, you can fix the defect in 10 to 30 minutes.

Types of bubbles on the screen Xiaomi: how to distinguish harmless from dangerous

Not all bubbles are equally harmful. Some just mess up the look, some signal serious display problems.

• 🔹 The air bubbles under the film are the most harmless, they're caused by dust, by improper gluing, or by poor material quality, and they can be easily eliminated, even without special tools.
• 🔹 Bubbles under the protective glass are a little more complicated, and if the glass is cheap or broken, the air can accumulate at the edges or in the center, and you need to be careful not to damage the oleophobic coating.
• 🔹 The detachment of the original glass glue is a bigger problem, more common on Xiaomi models with curved screens (such as the Mi 11 Ultra.
• 🔹 Bubbles under the matrix are the worst option, indicating moisture or damage to the interior layers of the display, and you can't do without replacing the screen.

How do you determine the type of bubble? Do a simple test.

1. You can easily push your finger on the bubble, and if it moves, it's the air under the film or the glass.
2. Light a flashlight at an angle. If the bubble is flashing through rainbow divorces, it's detachment of the adhesive layer.
3. Check if the picture on the screen changes in the place of the bubble. If so, the matrix problem.

⚠️ Warning: If the bubbles appeared after the phone fell or moisture hit, do not try to remove them yourself! This can be the beginning of corrosion of contacts under the display.

Causes of bubbles: from dust to factory marriage

To effectively remove bubbles, you need to understand why they arose. Here are the main reasons that are characteristic of Xiaomi smartphones:

Interesting fact: on Xiaomi models with ultrasonic fingerprint scanner (for example, Mi). 11T Pro) bubbles under the glass in the area of the scanner may block its operation.

If you recently bought a phone and noticed bubbles under the original glass, check to see if the factory film is removed. New Xiaomis often have transport protection, which users mistake for permanent coverage.

Method 1: Removing bubbles under the film without re-adjustment

If the bubbles appear under a protective film, rather than under glass, you're in luck -- this is the easiest problem to fix. Here's a step-by-step guide that works 90% of the time:

1. Preparation: Take a plastic card (like a bank card) and a microfibre wipe, make sure there's no dust on the screen.
2. Heat. Carefully heat the bubble with a hair dryer (at minimum power!) or put the phone on a warm battery for 2-3 minutes, which will make the film more elastic.
3. Flow the air. Smoothly move from center to edge, squeeze the bubble out with a map, move diagonally, not straight, so the air will come out more efficiently.
4. Fixing. After removing the bubble, press the film with a napkin for 10 to 15 seconds.

If the bubble doesn’t want to go away, try this life hack:

• 💧 Apply a drop of distilled water (or alcohol solution) under the edge of the film.
• 📱 Carefully pull the film upwards so that the liquid is distributed under the bubble.
• 🔄 Smooth the bubble with the card, expelling the air along with the liquid.

⚠️ Warning: Never use ordinary tap water for this purpose - mineral salts can leave stains under the film, which will then be impossible to remove.

Method 2: Re-sticking the protective glass - when it is not necessary to do without it

If the bubbles are under the protective glass, rather than under the film, then you can't just throw out the air.

1. Partial gluing - if the bubbles are only on the edges.
2. Complete glass replacement – if the defect is all over the area.

For partial re-painting, you will need:

• 🔥 Hair dryer (or construction, but at minimum temperature).
• 📏 Plastic scraper or mediator.
• 🧴 Glue for glass (e.g, LOCITE 3301 or B-7000).
• 🧻 Lilaless wipes and alcohol for degreasing.

Instructions:

1. Heat the edge of the glass with a hair dryer to make the glue softer.
2. Carefully tuck the glass with a scraper and raise it by 1-2 mm.
3. Apply a thin layer of glue to the cleaned surface of the screen.
4. Press the glass back, starting at the center, and iron it with a napkin.

Important: on Xiaomi models with curved screens (for example, Mi 11 Ultra or Mix Fold), it is almost impossible to glue the glass on your own - special adhesives and equipment are needed here.

Method 3: Radical methods – when nothing helps

If the bubbles don't disappear after all the manipulations, and the glass or film is worn out, all that remains is a complete replacement.

• 🔄 Buy a new glass with adhesive layer (for example, Spigen Glas.tR or AmFilm).The cost is from 300 to 1500 rubles depending on the model Xiaomi.
• 🛠️ Contact the service - if you are afraid of damaging the screen. The average price of resticking in Moscow is 800-2000 rubles.
• 📦 Replace with film if the glass is too expensive (relevant to the Xiaomi 13 Pro or Mix 4.

For those who decide to stick the glass on their own, here is a step-by-step instruction:

1. Carefully clean the screen with alcohol and a lilac-free napkin.


2. Remove the protective substrate from the glass and align it over the camera/dynamics.




3. Apply the glass carefully, starting at the top edge.




4.Smooth it with a plastic card, driving the bubbles to the edges.




5.Let the glue dry for 2-3 hours (do not use the phone at this time!).

Tip: Before buying glass, check its compatibility with your Xiaomi model. POCO F4 GT You need glass with a cutout under an ultrasonic scanner, and for the Redmi Note 12 - with rounded edges.

💡

Before you stick the new glass, turn on the phone's "No Sound" mode and turn off the vibration, so you avoid accidental touches of the screen that can displace the glass during installation.

What not to do when removing bubbles – common mistakes

Many users trying to remove bubbles only exacerbate the problem, and this is something that is strictly forbidden:

• 🔥 Use a hot hair dryer - overheating can damage OLED-Matrix (relevant to Xiaomi) 12/13 s AMOLED-screen).
• 🔪 Cheating glass with metal objects – this scratches the screen and can disrupt the sensor.
• 🧴 Stick glass onto a dirty screen – even microscopic dust particles will then turn into new bubbles.
• 💦 Try to “blow out” bubbles with your mouth – saliva contains acids that corrode the glue layer.
• 🧲 Using magnets – this can damage compass or wireless charging (on Xiaomi models with Qi).

Another common mistake is using superglue to fix glass, which eventually turns yellow and can leak into the matrix, permanently damaging it, and only specialized silicone-based adhesives are suitable for glasses.

⚠️ Note: On Xiaomi models with a subscreen camera (such as the Mi Mix 4), sloppy glass pasting can block the lens, causing the camera to shoot blurry.

Preventing: How to Avoid Bubbles on Xiaomi’s Screen in the Future

It's better to prevent a problem than solve it later, and here are some tips to help avoid bubbles:

• 🛡️ Buy glass with a guarantee – cheap fakes often peel off after a week.
• 🧼 Degrease the screen before the sticker (use isopropyl alcohol 90%+).
• 🌡️ Stick the glass in a warm room - at low temperature, the glue catches worse.
• 📱 Do not press the screen on the first day after the sticker - the glue needs time for polymerization.
• 🚿 Avoid moisture – even steam in the bathroom can cause detachment.

For Xiaomi models with curved screens (such as the Mi 11 Ultra), choose flexible edges that are more like the display shape and less flaky. Also look for oleophobic glass that lasts longer and gets less dirty.

If you change covers often, choose models with soft sides - hard edges can cling to the glass and tear it off.

💡

Even the best glass will last longer if you avoid temperature changes and mechanical stress, for example, do not leave your phone in the sun in your car in the summer - this is one of the main reasons for detachment.
