Replacing or initially installing the protective glass on Xiaomi, Redmi and POCO smartphones is a procedure that requires less special skills than perfect purity and patience. Modern screens are highly sensitive to touch, and the slightest mistake when sticking can lead to a decrease in tactile response or the appearance of unaesthetic artifacts. Many users are afraid to take up this business on their own, for fear of spoiling an expensive accessory or leaving hated dust particles under the layer of protection.
However, if you approach the process methodically and prepare the workplace, the result will be as good as in the service center. The main difficulty is that the displays of Mi devices often have rounded edges (2.5D), which requires special attention when centering the glass to avoid white stripes around the perimeter. In this article, we will examine all the nuances, from choosing the right accessory to the final polishing.
And don't neglect to prepare, thinking, "It's going to go down." It's in the dust that's floating in the air of the room that the main enemies of a perfectly flat sticker are hiding, and we're going to look at how to minimize the risks and get an outcome that will please the eye for months without detachment or bubbles.
Choosing the Right Glass Protection for the Display
The first and most critical step is to buy the right accessory.The market is full of offers, but not all of them are compatible with specific models of Xiaomi smartphones. Cheap counterparts often have the wrong geometry of cutouts for the speaker or front camera, and can also conflict with cases, peeling off at the edges.
Pay attention to the hardness of the material, which is usually labeled as 9H. This is the industry standard, meaning that glass will withstand contact with keys and coins in your pocket without scratching. Also important is the oleophobic coating, which repels greasy fingerprints and provides easy slip.
There are several types of glass, and the choice depends on your priorities:
- 💎 Transparent classic - retains the original color reproduction of the screen and does not distort the picture, being the most popular choice.
- 🌑 Matte (anti-reflective) - eliminates glare in the sun and makes the use of the smartphone more comfortable in bright light, but slightly reduces the brightness.
- 🛡️ 3D/5D Full cover – covers the entire face panel, including rounded edges, providing maximum protection, but more difficult in the sticker.
It is important to check the compatibility of the glass with your specific models. For example, the glass for the Redmi Note 10 may not fit the Redmi Note 11 due to the displacement of the dynamic camera capsule by only a millimeter. Always check the model before buying so as not to waste time on returns.
⚠️ Warning: Avoid buying black-framed glass if you are not 100% sure of compatibility. Different generations of Xiaomi smartphones may have different screen thicknesses, and a black edge of glass may overlap a portion of a useful image or, conversely, unstick.
The quality of the adhesive also plays a role, and in good kits it's uniformly applied and it doesn't break, and if you notice that the adhesive has already started to dry at the edges of the package before opening, it's best not to use this glass, it won't stick around the perimeter.
Preparation of the workplace and tools
The success of the operation depends on where and how you work, and the main goal is to eliminate dust. In a normal living room, microparticles are constantly circulating in the air, which settle on a sticky layer of glass, so the ideal place is the bathroom where you just turned on hot water to nail the dust with steam.
Provide bright lighting. A daylight lamp or a table lamp will help you see the smallest villi and specks of dust that will go unnoticed in dim light until it is too late. Also prepare a clean, flat surface, free of unnecessary objects.
The standard package of deliveries usually includes:
- 🧼 Wet wipe to remove fat and dirt.
- 🌬️ Dry walnut wipe for polishing.
- 🌀 Sticky sticker (vacuum) to remove micro-particles.
And you might also need tools that aren't always in the box, like a plastic card or a spatula to push bubbles out, and some craftsmen use tweezers to carefully remove the protective film from the glass itself so that they don't touch the adhesive layer with their fingers.
Before you start, wash your hands thoroughly with soap and wipe them dry. The fat from the skin of your hands is one of the main enemies of adhesion. If you have fingerprints on the glass before the sticker, these places can form air pockets.
☑️ Sticker-ready
Smartphone screen cleaning process
The most important step in the absence of bubbles is to thoroughly clean the Xiaomi display. Even if the screen seems clean, it probably has fat fingerprints and microdust. Start with the wet wipe that comes with it.
In circular motions, without pressing too hard, walk across the entire screen, paying special attention to the edges and corners where dirt accumulates most. Don't be afraid to use a napkin abundantly - it's better to wipe the excess than leave a greasy stain.
Then take a dry napkin and wipe the screen dry. The movements should be confident but neat. Your goal is to have perfect transparency and no divorces. Look at the screen from an angle in bright light -- if you see the stripes, repeat the procedure.
The final touch is to use a sticky sticker, which you can walk across the surface of the display, easily slapping, and it will collect all the microscopic villi and dust particles that you can't remove with a napkin, and it's these invisible particles that are the ones that most often cause bubbles after the sticker.
⚠️ Attention: It is strongly recommended not to blow on the screen with your mouth to blow off a speck of dust. As you exhale, you will spew out microscopic droplets of saliva that form greasy spots that can not be removed with a dry wipe.
If you accidentally touch the screen with your finger after cleaning, stop immediately and repeat the degreasing process again. Any touch negates previous surface preparation efforts.
Precise centering and installation technique
Now, to the most critical point: remove the bottom protective film from the glass (usually signed with the number 1 or has a tongue "Back"), try not to touch the fingers of the adhesive surface. Keep the glass behind the side edges.
Put the glass on your smartphone screen, combining the cutouts under the speaker, camera and sensors. Redmi and POCO models often use a drop-shaped cutout or hole in the screen that needs to be matched with high precision. Don't glue the glass right away!
Until you unplug the top protective film, you can move the glass freely, try it on. Make sure the indentations from the edges of the case are the same on all sides. If your smartphone has a noticeable bezels, try to position the glass symmetrically.
When the ideal position is found, gently lower the glass onto the screen, starting at one of the long sides (usually on the speaker side or charging connector, depending on the design) Let the adhesive layer grip. If the glass is flat, it will start sticking on its own, expelling air.
If you use a glass with a full adhesive base, it sticks instantly. Unless it's contoured, it can take longer. Anyway, after initial contact, don't try to move the glass abruptly so as not to damage the adhesive layer.
Removal of air bubbles and dust
Once the glass has fallen on the screen, carefully examine it. If there are air bubbles, they need to be kicked out. Take a dry napkin or a plastic card wrapped in cloth, and push the air out with confident movements from center to edge.
Large bubbles don't usually cause problems -- they go out of the glass easily; it's harder to deal with small bubbles that can stay in the center; sometimes it helps to just press your finger in the center of the bubble and walk to the edge.
If there's a speck of dust under the glass, it's more complicated. You'll need a thin needle or a scotch.
- 📌 Needle Method: Carefully lift the edge of the glass above the dust grain, insert a thin needle, tuck the dust grain and remove it, then press the glass.
- 🩹 Scotch method: Lift the edge of the glass, stick a piece of scotch sticky side up under the glass, press against the dust and pluck sharply.
Don't overpress.Severe pressure can damage the display matrix, especially in Xiaomi's budget models, where screens are less protected.
What to do if the glass cracks when the sticker is applied?
Once all visible defects are removed, wipe the surface with a dry wipe again, make sure there is no detachment around the perimeter, and if the glass is good and fit correctly, it should fit tightly throughout the area.
Final glue test and drying
The sticker process is complete, but the glue takes time to fully polymerize. Although modern adhesion works immediately, it is recommended to leave the smartphone alone for 1-2 hours to achieve maximum grip strength.
During this time, you don't have to use your phone, play games, or carry it in your pocket with your keys, but put it on a flat surface with your screen upwards, and that ensures that the glass will lie perfectly under its own weight.
Check the touchscreen. Do a multi-touch test by moving the icons all over the screen, including the edges, and if there are areas where the sensor is not responding, it may be that the glass is defective or has been glued with a skew that has created the voltage.
| Type of problem | Possible cause | Decision |
|---|---|---|
| White stripes around the edges | Incompatibility of glass and screen shape | Replace the glass with a model with a smaller surface area |
| Rainbow spots | High pressure on the sticker | Leave it for 24 hours, maybe it will pass by itself. |
| Peeling off corners | Fat on the edges or incompatibility with the cover | Remove the edges or change the cover to a wider one |
| Sensor's not working downtown. | Dust under glass or glass marriage | Try to remove dust or replace glass |
Make sure the speaker and proximity sensor are not closed. In some Xiaomi models, the dynamic conversational speaker is in a thin slit above the screen, and if the glass closes it, the sound will become quiet.
💡
If you notice after the sticker that the proximity sensor is not working correctly (the screen does not go out during a conversation), wipe the top of the glass with an alcohol wipe. Fat marks can interfere with the infrared sensor.
Frequent Mistakes and How to Avoid Them
Even experienced users sometimes make mistakes, and one of the most common is rushing, and when people try to stick the glass to speed, they miss the thorough cleaning or the cutouts are poorly matched, and the result is a curved glass with bubbles.
Another mistake is the use of poor quality consumables, cheap wipes can leave a pile that then turns into bubbles, always check the quality of components before you start working.
The temperature is also often ignored. If you just brought glass from the cold or from a hot car, let it lie at room temperature for 20-30 minutes. A sharp temperature difference can lead to condensation or changes in the properties of the glue.
⚠️ Note: Do not use household chemicals containing ammonia or acetone (varnish removal fluid) to clean the screen, which can damage the oleophobic coating of the Xiaomi screen itself and dissolve the adhesive on the protective glass.
Remember, the first glass is always harder. Don't worry if it doesn't work out perfectly the first time. With experience, you'll learn to feel the moment when you need to lower the glass, and do it almost automatically.
💡
The key to success is not speed, but careful surface preparation and no dust in the air, and it is better to spend 15 minutes cleaning than 5 minutes on a sticker.
In conclusion, the right glass sticker extends the life of your Xiaomi display and keeps it in the market for future resale. Follow the instructions, use quality materials, and your smartphone will be protected securely.
💡
Keep the packaging from the protective glass. If you decide to take it off after a year, the old glass can be gently put back in the box so it doesn't scratch other things or break.
