Modern smartphones Xiaomi Redmi line are equipped with high-quality displays, but even the durable glass Gorilla Glass does not guarantee complete protection from scratches or chips when falling. Owners often face the dilemma of trusting the factory film or purchase additional protection.
The process of gluing seems simple only at first glance, but it is the rush and lack of preparation that leads to bubbles and dust under the glue layer. To make the result pleasing to the eye and provide 100% protection, you need to follow the algorithm of actions. In this article, we will discuss all the nuances of surface preparation, centering and finishing for the Redmi Note, Redmi 10, Redmi 12 and other current versions.
Properly installed protection will not only protect the display, but also keep the touch sensitivity at a high level. Many users fear that the additional layer will worsen the screen response or distort the color reproduction, but the quality 3D and 5D glass from proven brands is almost invisible.
Choosing a protective glass for Redmi
The accessories market is full of offers, and it can be difficult to choose a really high-quality product. For Xiaomi smartphones with their specific cutouts for the front camera and curved edges of the screen, it is important to choose glass with precise geometry. Cheap analogues often have a smaller adhesive layer size, which causes rainbow zones or detachments to form along the edges.
Pay attention to hardness labeling. The optimal indicator is 9H, which means high resistance to scratches from keys or small things in your pocket, and an oleophobic coating that repels greasy spots and makes it easier for your fingers to slide across the screen is also important.
⚠️ Warning: Avoid perimeter black-framed glass if your Redmi has a specific proximity sensor.The black frame can block the sensor, causing the screen to go out during a conversation.
When buying, you should consider the following types of protection:
- 🛡️ 2D glass – completely flat, covers only the work area, leaving curved edges open; suitable for budget models.
- 🌊 3D glass - has curved edges that repeat the bend of the display, provides full surface protection.
- 💎 5D/9D Glass – a marketing name for glass with enhanced edge protection and increased transparency.
- 🔒 Privacy glass – darkens the screen at an angle, hiding the contents from prying eyes, but reduces brightness.
Don’t skimp on accessories, as cheap glass can crack at the first minor impact, not performing its main function. Quality silicone adhesive in expensive models provides better grip without forming air pockets.
Tools and workplace preparation required
Before you start the procedure, you need to organize a clean workspace. Dust is the main enemy when you stick it, so it's best to have the operation in the bathroom, first turning on the water to nail the dust, or in the kitchen after wet cleaning. Skirts can also lift microparticles, so close the windows.
A quality safety glass is usually complete with a set for installation, but its contents may not be enough.
- 💧 Wet wipe (alcoholic) for degreasing.
- 🧻 Dry microfiber for polishing.
- 🌫️ Sticky sticker (dust remover) for final cleaning.
- 🔦 Powerful flashlight or table lamp for illumination.
- 🃏 Plastic card or special spatula for purging bubbles.
☑️ Ready to stick
Make sure you have a bright light source on hand, and it's the side light that allows you to see tiny specks of dust that you can't see in normal light, and if you have a villi on the screen, you can create an air bubble underneath that can eventually crack the glass at that point.
It is also recommended to remove the case before work begins so that it does not interfere with the exact alignment of the accessory.Some cases have high sides that can conflict with the edges of 3D glasses, so check compatibility after installation.
Preparation of the screen of the smartphone Xiaomi
The quality of the protection fit depends 90% on how thoroughly you clean the screen. There are always microscopic traces of skin oil on the Redmi surface, even if the screen appears clean visually. Use a wet wipe from the kit to thoroughly wipe the entire display area with circular movements.
After wet treatment, be sure to go through a dry microfiber. The polish should be perfect: there should be no stains or villi from the fabric on the screen. If you notice that the napkin leaves the pile, it is better to use a lilaless fabric for optics or glasses.
⚠️ Warning: Never use household chemicals, window wipers or acetone to clean your smartphone screen.Aggressive substances can damage the oleophobic coating of Xiaomi's display itself.
The final stage of preparation is to use a sticky sticker, which is to go all over the screen, paying special attention to the corners and areas around the speaker, and it's often where the dust accumulates.
💡
If you don't have a sticker on hand, use a regular stationery tape rolled sticky side outwards into a ring on your finger, which is a great way to collect microdust.
Once you have seen the perfect cleanliness, don't touch the screen with your fingers and blow on it. Breathing contains microparticles of moisture that can settle on a sticky layer of glass or screen.
The process of gluing: step-by-step instructions
The most important thing is to remove the protective film from the adhesive layer of glass, which is usually labeled "1" or "Back." Take the film slowly, trying not to touch the sticky surface with your fingers. Keep the glass behind the side edges.
Place the glass above your smartphone screen without gluing it right away. Combine the cutouts under the speaker, camera and sensors. Modern glass for Redmi often has a special guide frame or is self-centered, but manual adjustment is still necessary.
Once you have achieved the perfect match:
- Carefully lower the glass on the screen, starting from one side (usually the speaker side).
- Easy press the center so that the glass "captures".
- If a self-adhesive base is used, the glue will spread across the screen on its own.
- If the glass is not glued completely, gently lift the edge and straighten your finger from the center to the edges.
Use a plastic card wrapped in a soft cloth to drive out the air. The movement should be from center to edge. Don't push too hard on the center of the screen so as not to damage the matrix.
💡
The secret to success is to take your time when combining the cutouts, and it's better to spend an extra minute trying on it than gluing it to dust.
If you notice that the glass has gone crooked, don't be afraid to take it off and try it again, but only if the glue hasn't frozen and dust has not been put on it, but each cycle reduces adhesion.
Removal of bubbles and defects
Even skilled craftsmen sometimes have small air bubbles, and if the bubble is large and near the edge, try to gently bend the nearest edge of the glass with your finger or tweezers and press back again, expelling the air.
Small bubbles, similar to rainbow spots, often pass independently during the course of the day. 24-48 The glue in quality accessories has the property of self-healing and distribution. Don't try to aggressively press them right away.
In case of dust falling under the glass:
- 📌 Take a tape and gently lift the glass from the side where the defect is located.
- 🌬️ With the sticky part of the tape, touch the dust on the glue layer of glass or on the screen.
- 📉 Stick the glass back, smoothing from the center.
If a villi is under the glass, it is more difficult to remove it, because it can create an air pocket, in which case only a complete glue with thorough cleaning will help.
| Type of defect | Cause of the occurrence | Elimination |
|---|---|---|
| A large air bubble | Uneven pressing | Throw to the edge with a finger or a map |
| Rainbow spots | Residual air/unevenness | Wait 1-2 days until the glue is completely dry |
| Point with villi | Dust in the air | Raise the edge, dust off with scotch |
| White stripe by the edge | Insufficient fit (not 3D) | Alas, this is a glass construct, it is not cured. |
Do not use needles or sharp objects to pierce bubbles – you risk damaging the display matrix or bringing dirt deeper.
Specificity of Redmi models with curved screens
The flagship models of the Redmi Note Pro series and some versions of Xiaomi often come with 2.5D or full 3D bending screens ("waterfall"). It is more difficult to stick protection on such devices, since flat glass simply cannot cover the bend.
There are two solutions for this: One is to use a hydrogel film that fits perfectly all curves, but it's worse to protect against heavy impacts; and the other is to buy special 3D glasses with a silicone adhesive layer around the perimeter.
Why do the edges peel off on curved screens?
When mounted on a curved screen, it is critical to warm the edges well with a hairdryer (not too hot air) after the sticker, which will help the silicone layer to spread better and lock at the radius.
⚠️ Warning: When working with curved screens, avoid heavy pressure on the edges in the first hours after the sticker.
