Xiaomi Mi Max 3 has a huge display that requires reliable protection from scratches and chips. Despite the use of durable glass Gorilla Glass, the screen remains vulnerable to keys, coins and accidental falls on hard surfaces. That is why owners often wonder how to properly paste the protective glass so that it lasts a long time and does not spoil the appearance of the device.
The sticker process may seem complicated because of the large size of the screen, but with the observance of technology, everyone can do it. The main thing is to prepare a clean workplace and have patience, because even the smallest speck of dust can spoil the result. In this article, we will discuss all the nuances of preparing, cleaning and fixing the protective layer on the touch panel of your gadget.
Many users are afraid to do this on their own, for fear of leaving prints or creating pockets of air, but with the right tools and step-by-step algorithms, you can get the perfect result the first time around. Let's look at what it takes to protect the screen properly.
Tools and workplace preparation required
Before the procedure begins, it is critical to organize the space, the ideal place is a table with good lighting, located away from dust sources, such as open windows or a running fan, and wet cleaning in the room before work will significantly reduce the risk of villi falling under the glass.
Not only will you need the protective glass itself, but you will also need a number of auxiliary materials that are often bundled or purchased separately, and you should pay special attention to the quality of the degreasing agent, because it depends on the strength of the adhesive layer to the surface of the display.
- 🧼 Microfiber wipe to remove large contaminants and fat.
- 🌬️ Alcohol napkin or special spray for deep cleaning.
- 💨 Sticky tape or scotch to remove the smallest dust.
- 📱 Plastic card or special spatula for purging bubbles.
Some craftsmen also use a backlit magnifier to better see fine dust particles on the black background of the screen. If you don't have professional tools, you can do with regular stationery tape and a bright lamp. As long as your hands are clean and your nails are short-cut so you don't scratch the Xiaomi Mi Max 3.
Choosing a high-quality protective glass for the Mi Max 3
The accessories market is crowded with offerings, but not all are equally good. For a smartphone as large as the Xiaomi Mi Max 3, it's important to choose glass with the right geometry. Cheap counterparts are often smaller in size and don't cover the entire usable area, leaving unprotected edges that take the hit first.
Pay attention to the hardness of the material, which is usually labeled as 9H. This means resistance to scratches from metal objects. Also important is the oleophobic coating, which repels fat and water, keeping your finger gliding pleasantly across the screen.
Black or clear glass?
There are two main types of glass: conventional bezel and Full Glue (with glue all over the surface). The first option is easier to stick, but can give a rainbow effect on the edges. The second option provides better sensitivity and appearance, but requires more accuracy when applied.
- 🛡️ Firmness 9H Protects against keys and knives in your pocket.
- 🖐️ Oleophobic coating prevents the appearance of greasy traces.
- 📐 Accurate fit to the dimensions of the Mi Max 3 eliminates gaps.
Screen cleaning process before sticker
The most critical step is to prepare the display surface, and any speck left on the screen will become a noticeable air bubble after the glass is glued, and start by thoroughly scrubbing the screen with a microfiber dry wipe, removing visible stains and prints.
Then use a wet alcohol wipe. Rub the screen in circular motions, paying special attention to the corners and edges where the dirt accumulates most. After wet treatment, be sure to walk through the dry cloth to remove moisture and villi.
⚠️ Warning: Never use household cleaning products for windows or mirrors, they can damage the oleophobic layer of the display itself and leave a dent.
The final touch is to use sticky tape, and you can walk it all over the screen, gently pressing and tearing it off to collect microscopic dust that you can't see, and do this in bright light, tilting the phone at different angles to see what's left.
☑️ Screen preparation checklist
Technology of application of protective glass
When the screen is perfectly clean, we move on to the sticker process itself. Take the protective glass over the edges, trying not to touch the adhesive surface with your fingers. Bring it to your smartphone, combining the cutouts under the speaker and camera with the corresponding elements of the Xiaomi Mi Max 3 body.
Carefully lower the glass onto the screen. If this is a silicone adhesive model, it will stick from the center. Don't push hard at that point, let the glue spread evenly. If you see the glass go crooked, you can gently lift it up and fix it until it's fully grasped.
To get the air out, use a plastic card wrapped in a soft cloth, or a special spatula. The movement should go from center to edge, pushing bubbles outwards. Pay special attention to the edges, because there are often air pockets.
💡
If the bubble is still left and not expelled, try to slightly press your finger on it during the course of the day. 10-15 Sometimes the glue needs time and warmth of the hands to melt and fill the void.
The table below shows the main problems that arise with the sticker and how to solve them:
| Problem. | Reason. | Decision |
|---|---|---|
| Rainbow spots | Bad fit around the edges | Use Full Glue glass or press the edges harder |
| White dots | Dust under glass | Carefully lift the edge and remove dust with scotch |
| Weak sensitivity | Thick glass or marriage | Check the sensitivity settings in the Settings |
| Separation of edges | Fat or moisture at the edges | Degrease the edges and tightly press for a few minutes |
Elimination of bubbles and dust under glass
Even the most experienced users sometimes have dust under the glass. If you notice a black dot or a white bubble, don't panic. Take a piece of tape, bend the edge of it to get a sticky tip, and gently lift the protective glass from the edge closest to the defect.
If you pick up the glass, you can take the sticky tip of the tape underneath it right to where the dust is, and you can touch the dust with the sticky side, and it will stick to the tape, and then you can lower the glass back and smooth the joint.
⚠️ Warning: Do not try to remove dust by swiping your finger across the glass at the fault site. You will only push the mote deeper or damage the adhesive layer, making the stain more visible.
If there's a little air bubble under the glass that's not being ejected, you can try to warm up the area, use a hair dryer at a minimum temperature, or just rub the bubble area with your finger for a minute, and heat will make the glue more elastic, and the air will come out.
💡
The key to the perfect sticker is to take your final pressing time, let the glass recline on its own for a few hours for maximum adhesion.
Glue polymerization and finishing procedures
Once the glass is glued and all the bubbles are removed, the process does not end. The adhesive layer takes time to fully polymerize and gain maximum grip strength. In the first hours of use, try not to expose the phone to shocks and put it in a tight pocket.
Wipe the surface of the glass with the final dry wipe to remove any possible fingerprints left in the process. Make sure the sensor responds to touches across the area, especially in corners where the Xiaomi Mi Max 3 often has curvatures.
To test the quality of the installation, you can run a touchscreen test. Type ##6484## in the phone app to get into the engineering menu, and select "Touchpanel." Swipe your finger through all areas of the screen, making sure the lines are drawn without tears.
- ⏳ Leave the phone on. 1-2 idle-hour.
- 🧹 Wipe glass with microfiber to remove stains.
- ✅ Check the sensor in the corners and in the center of the screen.
