Owners of Xiaomi, Redmi and POCO smartphones know that modern screens, whether AMOLED or IPS, require careful handling. Even the durable glass Gorilla Glass does not always save from scratching keys in your pocket or chipping in the event of an accidental fall. That is why installing a protective glass becomes the first action after buying a new gadget, allowing you to preserve its product appearance and functionality of the display for many years to come.
The procedure of gluing seems simple only at first glance, but at home it is easy to make a mistake that will lead to the appearance of bubbles or villi. In this material, we will analyze all the subtleties of preparing the work area, choosing quality accessories and the installation process itself, so that the result will please you with perfect transparency and tactile sensations.
You don't have to be a service center master to do this on your own, but the main thing is to have patience, good lighting and follow proven algorithms of actions, which we will discuss in detail below, paying attention to the nuances that are characteristic of the Chinese manufacturer's devices.
Choosing a high-quality protective glass for Xiaomi
The first step to successful protection is to buy the right accessory.The market is full of offers, but not all of them are equally useful for your Xiaomi. Cheap counterparts often have a low-quality oleophobic coating that wears off in a couple of weeks, making the screen greasy and less touch sensitive. Choose proven Original brands or certified accessories that ensure the thickness and rounding angles (2.5D or 3D) meet your model's specifications.
Note the hardness of the material, which is usually labeled as 9H. This means resistance to scratches from metal objects, but does not guarantee indestructibility when hitting a stone. Also consider the type of coating: matte glass hides prints, but can give a rainbow effect, while transparent ones retain the brightness of the Super AMOLED matrix.
⚠️ Attention: When buying 3D-Full-adhesive glass base, make sure it's compatible with an optical fingerprint scanner if it's embedded in your smartphone screen.
It's also important to check the kit, and ideally, in addition to the glass itself, the box should contain wet and dry wipes, a sticky sticker to remove dust, and perhaps a template frame for perfect positioning, all of which make it much easier and reduce the risk of marriage.
- 🔍 Firmness 9H Provides protection against scratches with keys and a knife.
- 💧 Quality oleophobic coating repels fat and water.
- 📐 The exact match of the hatches under the speaker and camera is critical for Xiaomi.
- 🖐 3D-coating ensures gluing throughout the area, including the edges.
Preparation of the workplace and tools
The success of an operation depends 80 percent on the conditions in which it is performed. Dust is the main enemy of any adhesive layer. Even a microscopic villi trapped under a glass will create a visible air pocket that cannot be removed without removing the protection. So choose a room that has not been cleaned for a long time, and preferably moisten the air or wipe the floors with a wet cloth to nail the settled dust.
Organize your workspace. You'll need a flat, stable surface, like a desk. Prepare all the tools in advance: microfiber, alcohol wipes, scotch tape, and of course, the protection itself. Make sure the lighting is bright enough to see the smallest particles on the screen, but the direct light doesn't hit your eyes, creating glare.
Before you start, wash your hands thoroughly with soap and wipe them dry. Fat fingers will leave marks on the adhesive layer or the screen itself, which will worsen the adhesion. If you have long hair, it is better to remove it under the hat or stab it so that it does not fall on the low-fat surface of the display at the most critical moment.
☑️ Checklist for preparation for the sticker
Smartphone screen cleaning process
The most important step is to prepare the display surface, and even if the screen appears to be visually clean, it must have microscopic particles of fat and dust on it. Start with a wet alcohol wipe from the kit. Wash the entire screen area carefully, including the corners and edges where most pollution usually accumulates.
After wet treatment, take a dry microfiber wipe and dry the screen. The movements should be soft, without much pressure. Your goal is to achieve perfect smoothness and no divorces. Any remaining divorces can become centers of crystallization of air bubbles in the future.
The final touch is to use a sticky sticker, which is to go all over the surface of the display, gently pressing and tearing it off, and it will remove the smallest villi that you could have left after wiping, and if you don't have a sticker on hand, you can use a regular wide tape, but be careful not to leave any sticky marks.
What to do if dust gets caught in the process?
Technology of adhesive protective glass
Now, to the installation process itself, take the security glass by the ends, trying not to touch the adhesive surface with your fingers. Combine the cutouts on the glass with the speaker, camera and light sensors on your Xiaomi. Modern models often have an automatic adhesive base that itself "graves" to the screen if the glass is laid flat.
Put the glass on the screen, making sure that the boundaries match perfectly. Don't push the center! Easy press the top over the speaker to lock in. If the glass is flat, it will start sticking from center to edges, displacing the air. If you see that the glass has fallen crooked, you better take it off right away, clean the screen again and try again until the adhesive layer has lost its properties.
Once the glass is grasped, take a plastic card (usually included) or a soft fabric. Starting from the center, with light pressure, go to the edges, driving out the air residue. Pay special attention to the edges, as there are often micro-bubbles.
💡
Key point: Never glue glass to the screen on, as heat from a working display can accelerate the polymerization of the adhesive and create an uneven layer.
Removal of defects and bubbles
Even the most experienced users sometimes have small pockets of air, and if the bubble is close to the edge, just try to move it to the exit, and if the bubble is not going away, there may be a speck of dust stuck underneath, which would require the partial gluing we mentioned earlier.
Sometimes you have what's called rainbow patches or areas where the glass doesn't fit tightly, and this could be due to the design of Xiaomi's case, where the edges of the screen are rounded (2.5D) and the glass is flat, and in such cases, it's physically impossible to fit the entire area, and it's not a marriage.
You can use a warm-up method to remove stubborn bubbles, but be very careful: the heat should be minimal. You can warm up a little with a hair dryer at a minimum temperature, but you should just leave the phone in the sun or in a warm place for a couple of hours, the glue will soften and spread, filling the voids.
| Type of defect | Cause of occurrence | Elimination |
|---|---|---|
| Big dust bubble | Villus hit | Remove the glass, remove dust with a sticker |
| Small air bubbles | Insufficient pressing | Carry the map from center to edge |
| White stripes around the edges | Incompatibility 2.5D/3D | Warming up or accepting (this is the norm) |
| Rainbow divorces | Poor quality of oleophobics | Replace glass with better quality |
⚠️ Warning: Do not use sharp objects (needles, scissors) to pierce bubbles on the glass. You can damage the display matrix or leave scratches that will interfere with swipes.
Frequent Mistakes and How to Avoid Them
One of the most common mistakes is rushing. Users often don't clean the screen completely or don't fit the glass properly the first time, and as a result, you have to redo the work, which reduces the adhesiveness of the layer. Always check the result after each step of cleaning with side lighting.
Another mistake is to use aggressive chemicals to clean. Alcohol-containing wipes are acceptable, but acetone or solvents can damage the oleophobic coating of the screen itself or melt the adhesive on the protective glass. Use only those products recommended by the accessories manufacturer.
And many people forget to remove the transport film from the inside of the glass itself before they stick it, usually labeled with a "1" or a "Back" label. If you stick the glass with this film, it won't hold and it will fall off quickly. Always check for protective films on both sides before you start work.
💡
Expert advice: after you stick the glass, don't put the case on immediately. Let the glue finally polymerize within 1-2 hours. The case can put pressure on the edges and cause detachment.
Care for protective coating
Once installed successfully, it is important to properly care for the new layer. Regularly wipe the screen with soft cloth. Avoid the use of aggressive household chemicals. Over time, the oleophobic coating will wear off and the glass will become worse slip, in which case it can be replaced, because the procedure has already been worked out.
If you carry your phone in your pocket with keys or change, make sure the case has protective sides that rise above the screen level.This will create an extra air cushion and protect the glass from direct contact with hard objects when falling.
Check the edges of the glass regularly, and if you notice that it has started to peel off or crack, it is better to replace it immediately. The crack can spread, and the sharp chipped edge can injure your finger or damage the touchscreen when pressed.
