How to properly paste the protective glass on the watch Xiaomi: instructions with photos and tips

The protective glass on Xiaomi smartwatches is not just an accessory, but a necessity to preserve the original look of the screen. Even the most durable factory coating is covered with microcracks from impacts, scratches from metal straps or keys in your pocket. But many users face the problem: the glass peels off every other day, bubbles appear, or the screen stops responding to touch. In this article, we will analyze the step-by-step sticking algorithm that guarantees the perfect result the first time — without stains, dust and defects.

Xiaomi Watches (Be it Mi Band) 8 Pro, Watch 2 Pro or Watch S3) — And it's very, very curved, and it's very compact, and that makes it very difficult, because the standard methods that work for smartphones are often very difficult. 5 We've selected the most reliable way to install it, and we've also made a table of the compatibility of the glass with the popular watch models so you don't make the wrong choice, and we'll also reveal the secrets to avoiding common mistakes that cause you to make. 70% Users are gluing glass over 2-3 once.

Why the protective glass on Xiaomi watches is unstuck: 5 main reasons

Before we go into the manual, it's important to understand why previous attempts might have failed, and often the fault is poor materials or technology disruption, but there are also hidden nuances.

First, improper surface preparation. Even invisible dust particles or greasy finger marks reduce the adhesion of the glass to the screen. Second, incompatibility of materials: for example, the hydrophobic coating on some Xiaomi Watch models repels the adhesive base of cheap glasses. Third, skewed installation - the slightest shift leads to detachment of the edges.

• 🧴 Fat or sweat on the screen: even after wiping with alcohol, microscopic traces remain, if you do not use special wipes.
• 🌡️ Temperature: The glue on the glass loses its properties if the glue occurs at a temperature below +18°C or higher +30°C.
• 🔍 Low quality glass: thin (less than 0.2 mm) or too rigid glass does not repeat the curves of the screen.
• ⏳ Shelf life of glue: glass that has been in storage for more than a year, lose stickiness.
• 🤏 Installation pressure: Excessive pressing pushes the glue to the edges, leaving the center unfixed.

Another common mistake is to use universal glass instead of specific glass for a particular model, such as the glass for Xiaomi Watch. S1 It's not going to work for the Watch 2 Pro because of the difference in radius of the display, and it's going to peel off at the edges after a few days.

What kind of protective glass to choose for Xiaomi watches: a comparison of materials

The market offers three main types of glass, and each has pros and cons, and let's go through them in detail so you make an informed choice.

For most Xiaomi models, the best choice is tempered glass. 9H rounded (3D). It's very protective against scratches and impacts, but it requires precise installation. Flexible films are cheaper, but they last only 2-3 months, and liquid glass is difficult to apply without experience.

⚠️ Note: Do not buy a full-cover glass for a physical-button watch (e.g. Xiaomi Watch). S1). They block access to the buttons, making the watch unusable.

Also consider the radius of the screen when choosing. S3 he composes 2.5D, And Mi Band 8 Pro — 2D (Universal glass is rarely perfect, so look for options marked "exact model cutout".

💡

Before buying, check the reviews about a particular glass on marketplaces. Often in the comments, users post photos of the real sticker, where you can see how exactly the cutouts for the sensors and the speaker match.

Preparing Xiaomi watches for gluing: a step-by-step checklist

Successful installation of the protective glass depends on preparation for 80% of the time, and if you miss one point, you risk bubbles or bad fixation.

Start by turning off the clock, and this prevents accidental touches of the screen while you're working, then remove the strap, it'll interfere with the installation, and use 70 percent isopropyl alcohol and a microfibre wipe without the pile to clean the screen, and importantly, don't use household alcohol or wet wipes, they leave a divorce.

Next step is to remove the dust. Use a special sticky scotch (complete with glass) or scotch for painting. Stick it to the screen and rip it off sharply, it will remove even invisible particles. Repeat the procedure 2-3 times.

Pay attention to the conditions in the room:

• 🌡️ Air temperature: 20-25°C (at lower glue, poorly fixed).
• 💧 Humidity: not above 60% (high humidity leads to condensation under glass).
• 🕯️ Lighting: bright directional light (such as a desk lamp) will help you see the dust particles.

⚠️ Warning: Do not use a hair dryer or heater to dry the screen.A sharp temperature drop can damage AMOLED-Matrix in the Xiaomi Watch S3 Watch 2 Pro.

If you're applying liquid glass, you can also degrease the screen with a white spirit (sold in autochemistry stores).

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

Now, to the most critical stage, we'll look at two methods: dry (for hardened glass) and wet (for flexible film). For most Xiaomi models, the dry method is suitable.

Method 1: Installation of tempered glass (dry method)

1. Take the glass out of the package with the edges. Don't touch the adhesive side!

2. Remove the protective film on one side of the glass (usually marked with a blue strip).

3. Carefully apply the glass to the screen, combining the cutouts for sensors and buttons.

4. With a light movement, press the center of the glass and gradually point your finger from the center to the edges, squeezing out the air. Use a plastic scraper (comes with a kit) to smooth the glass.

5 Check from different angles for bubbles, if there are any, gently tuck the glass in and reglue it.

For models with curved screen (Watch) S3) use 3D-glass and slightly warm it with a hair dryer (temperature not above 40)°C) before installation, this will make it more plastic.

Method 2: Application of liquid glass

1. Apply 2-3 drops of the composition on the screen and evenly distribute them with a microfibre wipe.

2 Wait 5 minutes - during this time the solution is polymerized.

3. Remove the excess with a dry wipe. Complete hardening takes 12-24 hours.

Liquid glass is less visible on the screen, but it lasts only 6-12 months. To prolong its life, avoid washing the watch with soap.

How to check the quality of the sticker: 4 tests

Take your time to put on the strap and use the watch - first make sure the glass is installed correctly.

• 🔍 Visual inspection: look at the screen from an angle - there should be no rainbow divorces (air under glass evidence).
• 👆 Touch test: Check the screen's response to swipes and taps in all areas. Delays or dead zones indicate a bad fit.
• 💡 Backlight: in a dark room, illuminate the screen with a flashlight - the shadows on the edges will indicate detachment.
• 🛠️ Durability: with a light nail, run across the glass - if there is a scratch, the protection is poor quality.

If the watch supports Always-On Display (e.g. Xiaomi Watch 2 Pro), turn on this mode and check if the image under the glass is distorted.

⚠️ Warning: If the screen becomes less sensitive after gluing, reset the calibration settings in the watch menu: Settings → Display. → Calibration of the sensor. That'll solve the problem 90 percent of the time.

For additional check, take a picture of the watch screen at maximum brightness, and the photo will show defects that are not visible to the naked eye.

Frequent Mistakes and How to Avoid Them: The Experience of Masters

Even when you follow the instructions, you make mistakes that make you lose your effort, and we surveyed 15 smartwatch repairers and compiled a list of the most common mistakes.

Another common mistake is to glue the glass, and every time you tear the glass off, there's a sticky layer on the screen that's hard to remove without a trace, and if you don't, you better use a new glass.

The masters are also advised to avoid glass with UV-It's a Xiaomi watch that requires a special lamp, and without it, the glue stays sticky and collects dust.

💡

The most common reason for glass detachment is failure to comply with the "run-in period." In the first 12 hours, the glue gains strength, and any pressing or moisture can disrupt this process.

Care for hours after gluing: extending the life of the glass

Even perfectly installed glass will not last long if you do not follow the rules of care.

• 🚿 Avoid prolonged contact with water, especially hot water, even with 5 models. ATM (For example, Xiaomi Watch S3).
• 🧼 Do not wash your watch with soap or gel – it destroys the oleophobic coating of glass.
• 🔥 Do not leave the watch under direct sunlight (on the torpedo of the car, windowsill). UV-The rays make the glass brittle.
• 🛠️ For cleaning, use only microfiber soaked in distilled water.

If you have small scratches on the glass, you can polish them with GOI paste (sold in autochemistry stores), apply it to a cotton-coated disc and polish the damaged area in circular motions. For deep scratches, this method will not work, you will need to replace the glass.

The average lifespan of quality tempered glass is 12-18 months, flexible films last 3-6 months, liquid glass up to a year, and if you use it, you have to change protection more often.
