How to properly paste glass on your Xiaomi phone: the full guide

Display protection is the first thing to think about for the owner of a new smartphone Xiaomi, Redmi or POCO. Modern screens are made of durable glass, but even microscopic sand or keys in your pocket can leave irremovable scratches on them. Installing a quality protective glass (tread) is the most effective way to preserve the product appearance of the device and avoid costly replacement of the matrix in the future.

The process of sticking is often difficult for beginners who are afraid of creating air bubbles or accidentally breaking the screen with pressure, but with a minimum set of tools and technology, this procedure can be done at home with factory quality, and it is important to understand that surface preparation takes 90% of the time of the operation.

In this article, we will take a look at each step, from the selection of consumables to the final polishing, and you will learn why some Xiaomi models with curved edges may require special glue, and how to avoid villi getting under the film. Following the instructions will help you save money on services of the service center.

Selection of protective glass and preparation of the workplace

Before action begins, you need to decide on the type of protection. The accessories market for Xiaomi is huge, and not all glasses are equally useful. There are models with full coating (Full Cover), which cover the entire screen, including curved edges, and the usual flat options. For flagship models of the Mi or Xiaomi series with a curved screen (Curved), it is better to choose silicone adhesive layer glass, as they better repeat the geometry of the display.

The critical parameter is Mohs hardness. High-quality treads are labeled 9H, which means high resistance to mechanical damage. Also worth noting is the oleophobic coating, which repels greasy finger marks and makes it easier to slip. Cheap analogues quickly lose these properties, turning into a "magnet" for fingerprints.

⚠️ Warning: Do not buy glass without packaging or in transparent plastic bags without protective stickers. There is a high risk that the sticky layer has already got dust that cannot be removed at home.

Preparing the workplace is key to success. You'll need a flat, well-lit surface. The ideal option is to have a desk by the window in daylight, because in artificial lighting, small specks of dust may not be noticeable. Rub the table with a damp cloth in advance to lift the settled dust, and let the surface dry.

Prepare clean hands for work, wash them with soap and dry them with a towel that leaves no pile, and the fat from your fingers can damage adhesion or leave traces that you can see after you stick them, and make sure that there are no drafts in the room that can dust off the floor or clothes.

Essential tools and supplies

Often, expensive safety windows are already packed, but for professional results, it is better to prepare the tools yourself. The main enemy when sticking is dust, so the arsenal should be aimed at removing it. You do not need complex equipment, simple enough things that are in every house.

Below is a list of what should be on the table before the procedure begins, and the absence of at least one element can lead to bubbles or skewedness.

• 🧼 Degreasing: alcohol wipes (usually included) or isopropyl alcohol. They remove the fat film.
• 🌬️ Scotch or sticky tape: required to remove the smallest dust particles from the screen immediately before the sticker.
• 💨 Pear or air spray: used to blow away static dust. mouth blowing is not recommended, as you may accidentally splash saliva on the screen.
• 🧽 Microfiber: special fabric without pile for the final wipe of the screen.
• 💳 Plastic card or rakel: necessary for expelling air bubbles from under glass.

Special attention should be paid to the adhesive composition. Standard glass has a silicone layer that sticks itself. However, for Xiaomi models with 2.5D or 3D screens (for example, Xiaomi Mi 10/11/12 Ultra, Redmi Note Pro with a bend), often require glass with liquid glue (UV glue) or a special frame. Under normal conditions, we are considering the option with a standard silicone layer, which is suitable for 90% of devices.

Screen cleaning process: the most important step

The quality of the glass fit depends on the cleanliness of the display surface of Xiaomi. Any grain of sand, even microscopic, will create an air cushion that will be visible as a white dot, so the cleaning step should be carried out as carefully and without haste.

Use a wet alcohol wipe first. Rub the screen in circular motions, paying special attention to the corners and edges where the dirt from the case usually accumulates the most. Don't be afraid to press - modern Xiaomi matrices are protected by durable glass Gorilla Glass or Dragontrail, you can not damage them with a napkin.

After you're wet, take a dry wipe or a clean microfiber and dry the screen. It should be free of stains. Now turn on the flashlight on another phone or use a bright lamp and look at the display at an angle. If you see villi or specks, use the sticky side of the tape to gently lift them from the surface.

⚠️ Warning: Never use household chemicals, window cleaners or acetone to clean the screen. Aggressive solvents can damage the oleophobic coating of the display itself, making it dull.

The final touch is to use a pear or a can of air. Blow the entire perimeter of the screen, especially the dynamic speaker at the top, where dust can fly out during the sticker process. The time between the final blowout and the application of the glass should be no more than 10-15 seconds, so that new dust does not settle on the screen.

Technology of the sticker: step-by-step instructions

The most critical moment is now: Take the glass sideways, try not to touch the adhesive layer with your fingers, hold it to the screen of a Xiaomi smartphone and try it on the spot without removing the bottom protective film, make sure that the cutouts under the speaker and the camera match, and the side frames are symmetrical.

Carefully remove the bottom layer. Do this quickly to minimize the glue's contact with air. Immediately, following the fitting you did, bring the glass to the screen. Start gluing it on one side (usually on the bottom or top, where the speaker is), gradually lowering the glass onto the display. The silicone layer will spread over the surface, expelling the air.

💡

If you use glass with a frame, first glue the frame itself around the perimeter, make sure that it sits flat, and only then glue the central part of the glass.

If the glass is crooked, don't panic. Until it's pressed hard, you can gently lift it around the corner (using a suction cup or nail) and fix it. Silicone glue allows you to make several attempts at positioning, the main thing is to keep the dust from getting between the layers at this point.

Once the glass is on the screen, take a plastic card wrapped in a soft cloth, or a special rackel. Start driving air from the center to the edges. The movements must be confident, but not too strong, so as not to damage the matrix. Pay special attention to the edges, which is where the air pockets are most often left.

In some cases, especially in models with heavily curved edges, the glass may not stick around the perimeter. This is normal for flat-glue glass. If the gap is too large and dust is stuffed in, you can use a special glue gel to fix the edges, but this requires great care.

Fixing defects: bubbles and dust

Even skilled craftsmen sometimes have defects. If you notice an air bubble under the glass, try to move it to the nearest edge. If the bubble does not go away, then there is a mote inside, in which case you need to carefully lift the edge of the glass above the problem area, insert a piece of tape under it (sticky side up), pick up a mote and remove it.

There's a special method to remove dust from under glass, using scotch tape: cut a narrow strip of scotch; lift the edge of the protective glass above where the dust is visible; insert a sticky piece of scotch under the glass, trying to touch the dust on the screen or on the glue layer of glass with the adhesive. After removing the mortar, gently lower the glass and smooth it out.

⚠️ Warning: Do not use needles or sharp objects to chase bubbles! you can scratch a touch or damage the matrix, which will lead to black spots or non-functioning areas.

If you have a little bit of bubbles left behind the sticker, called the rainbow effect, don't worry, because of the structure of the adhesive layer, and these defects usually disappear on their own within a few hours. 24-48 hours when the glue is completely polymerized and fills all the micro-units of the display Xiaomi.

Features for Xiaomi models with curved screen

Owners of Xiaomi’s flagship devices (Mi series, Xiaomi 13/14 Pro) often face a problem: conventional glass does not hold on the edges or peel off after a couple of days.

There are two solutions for this: One is using UV-adhesive glass, and it comes with a liquid glue that is applied to the screen, and the glass is placed on top, and the structure is illuminated by an ultraviolet lamp, and the glue solidifies, filling in all the curves, and this is the most reliable, but also the most risky method: if the glue hits the speaker or buttons, the phone can fail.

The second option is a special frame-converter, which is a plastic frame that sticks around the perimeter of the screen, creating a vertical sideboard, and this frame is already glued to a regular flat glass. It's less reliable than the one that's on the side. UV-glue, but safer for smartphone electronics.

💡

For curved screens Xiaomi is best suited glass with silicone adhesive layer (not to be confused with conventional perimeter glue) or UV-glass installed by professionals.

When you install protection on these models, be sure to remove the case. Many dense cases can press on the edges of the glass, gradually peeling it off. If the problem persists, consider using a hydrogel film that better fits complex shapes, although it is worse protects against heavy impacts.
