What kind of protective glass to choose for Xiaomi Redmi: types and features

There are dozens of glass options on the market, from cheap Chinese to premium Japanese, but not all of them are suitable for Redmi.

1. Thickness: Optimal range 0.2–0.33 mm Too thin glass (0.1–0.15 mm) is quickly scratched and thick glass (0.5 mm) is scratched.+) Degrades screen sensitivity and may interfere with the fingerprint scanner (if it is built into the display).

2. Hardness. Measured on the Mohs scale. Enough for everyday use. 9H — This is enough to protect you from keys and coins. 9H+ or 10H They are usually more expensive, but their strength is justified only for extreme conditions (for example, for builders).

3. The shape of the edges. For a flat-screen Redmi (e.g. Redmi). 10A) This is a glass with straight edges. 2.5D or 3D-bending (like the Redmi Note 12 Pro) requires glass with rounded edges, otherwise it will recede along the sides.

4. Coverage. Oleophobic coating is mandatory, without it, there will be fingerprints on the glass. Some brands, like Spigen or Nillkin, add anti-reflective coating, but it slightly reduces the brightness of the screen.

Here is a comparison table of popular brands of glass for Xiaomi Redmi:

⚠️ Warning: Don't buy glass without a model of the phone! Even the Redmi Note 11 and Redmi Note 11 Pro have different screen sizes. Always check compatibility in the product description.

If you're in doubt about which glass to choose, focus on the reviews for a particular model. e.g. Redmi Note 13 Pro+ Users often recommend Nillkin CamShield, which is specifically designed for in-screen cameras.

Preparation for installation: what you need and how to avoid errors

Before you stick the glass, you have to prepare the surface carefully, and this is the most important step -- if you skip even one step, bubbles or dust under the glass are guaranteed.

• 🧴 Alcohol wipes (or isopropyl alcohol) + Do not use wet hand wipes! - they leave divorces.
• 🧹 Microfiber fabric (e.g., from a glasses kit) that doesn't scratch the screen and collects dust well.
• 💨 A vacuum cleaner or a tape to remove dust, ideally a special sticker made of a set of glass.
• 📏 Plastic card or scraper for squeezing bubbles.
• 🔍 Bright lamp or flashlight – to check the screen for dust from different angles.

Now we move on to step-by-step preparation:

1. Turn off the phone and remove the case (if any). The case may interfere with the precise installation.
2. Wipe the screen with a dry microfiber to remove visible contamination.
3. Apply some isopropyl alcohol on a napkin and thoroughly wipe the entire screen, including the edges.The alcohol will remove the fat and prints.
4. Hold the screen to the light and look for dust, and if you see the particles, carefully remove them with tape (stick and tear).
5. Wipe the screen with a dry microfiber once again – it should now be perfectly clean.

⚠️ Note: Do not install in a dusty room (for example, during repairs) or in high humidity (in the bathroom after showers.

Many people skip the step of checking the glass before installation.

• Take the glass out of the package and inspect for microcracks or chips.
• Check if the cutouts for the speaker and camera match your Redmi model.
• If the kit has a sticker-positioner (for centering), glue it to the screen before removing the protective film from the glass.

Step-by-step: how to glue glass on Xiaomi Redmi without bubbles

Now, to the most critical stage, follow the instructions slowly and carefully, the enemy is in a hurry. №1.

1. Remove the protective film from the glass on one side only (the one that will stick to the screen).Do not touch the other side, it protects against scratches during installation.

2. Carefully apply the glass to the screen, combining the cutouts under the speaker and the camera. If you use the positioner, just lower the glass on it - it will stand correctly.

3. Press the glass in the center with a light press, then gradually press from the center to the edges. Don't push hard, just a light touch.

4 Take a plastic card and gently swipe it from center to edge, squeezing out possible bubbles. Move in one direction (for example, from top to bottom).

5. Check the results under bright lights. If you see small bubbles, don't panic -- they usually disappear after 12 to 24 hours. You can try to squeeze the big bubbles out with a map, but if it doesn't work, you'll have to glue them back.

⚠️ Warning: If the glass is crooked, don't try to move it after you stick it, it will cause dust and bubbles.

For models with curved screen (for example, Redmi) K60 Pro) the process is a little more complicated:

• Use glass with flexible edges (usually described in the description "3D Full Cover").
• When gluing, do not press on the edges - they should "leak" the bend themselves.
• For better fixation, you can slightly warm the edges with a hairdryer at minimum power (not hot air!).

If you're afraid of making a mistake, check out the video manual for your model. For example, for Redmi Note 12 on YouTube, there are detailed guides with nuances of installation.

Before you finally fix the glass, turn on your phone and check if it's interfering with the sensor, and if the screen responds to touch without delay, it's okay.
