Xiaomi Redmi Note screen 7 diagonally 6.3 inch and resolution FHD+ (2340×1080) — One of the most vulnerable parts of a smartphone, even a slight fall or contact with keys in your pocket can leave scratches or cracks on it, and a properly selected protective glass not only prevents mechanical damage, but also preserves the tactile sensation of touch control. However, the market offers dozens of options - from budget films to premium films. 9H-oleophobic.
In this article, we'll look at the unique features of the Redmi Note 7 screen that affect the choice of protection: rounded edges, sensor location, compatibility with cases. You'll learn how to distinguish between high-quality glass and fakes, which materials are better at dealing with impacts, and why cheap "universal" solutions often lead to disappointment.
Why Standard Glasses Are Not Good for Redmi Note 7
Many users mistakenly believe that any glass marked “6.3 inches” is suitable for their smartphone, but the Redmi Note 7 has a unique screen shape with two key features:
- 🔹 Rounded edges (2.5D) — glass should repeat the bend of the display, otherwise there will be gaps along the edges, where dust will be clogged.
- 🔹 Cut for the front camera – unlike the “bangs” of the Redmi Note 8, a small circular hole (“dot-notch”) is used here, which many universal glasses simply ignore.
- 🔹 Approximation and illumination sensor – located to the right of the camera; if the glass closes it, the automatic brightness adjustment will stop working.
In addition, the Redmi Note 7 has oleophobic coating on its home screen, which wears off over time, and a high-quality safety glass should restore it, not worsen the slip of the finger. Cheap glasses often make the screen sticky after a month of use.
⚠️ Note: If you use a case with "ears" (protruding edges around the screen), make sure that the thickness of the glass does not exceed 0.33 mm. Otherwise, when pressing the edges of the display, "rainbow" spots may appear due to pressure.
Types of protective glass: a comparison of materials and technologies
All the glass for the Redmi Note 7 are divided into 4 main categories, distinguished not only by price, but also by the level of protection, tactile sensation and durability.
| Type of glass | Hardness (Mohs scale) | Impact protection | Oleophobic coating | Term of service | Price (rupe) |
|---|---|---|---|---|---|
| 9H Tempered Glass | 9H | ⭐⭐⭐⭐⭐ | Eat (1-2 years) | 2–3 years | 300–800 |
| Hybrid (glass + film) | 8H–9H | ⭐⭐⭐⭐ | There are (6-12 months) | 1-2 years | 500–1200 |
| Liquid glass (nano-coating) | 6H–7H | ⭐⭐ | There are (3-6 months) | 6-12 months. | 800–1500 |
| Shock-resistant film (TPU/PET) | 3H–4H | ⭐⭐⭐ | No. | 3-6 months. | 100–300 |
9H-Glass is the most popular choice because of its price-protection balance, which can withstand a drop from a height of 1.5 meters to a hard surface (assuming the impact is on the glass, not on the edge of the smartphone). with a strong impact, the glass can split, leaving micro scratches on the display.
Hybrid glass combines a hard layer (9H) with an elastic base that extinguishes vibration when struck, which is the best option for those who often drop their phones, and liquid glass is only suitable as an additional protection — it will not save from cracks, but will prevent scratches from sand or keys.
Top.-5 Protective glass brands for Redmi Note 7
Not all manufacturers take into account the features of the Redmi Note 7. We tested 15 brands and selected those that guarantee an accurate fit, retain screen sensitivity and do not turn yellow over time:
- 🥇 Spigen Glas.tR EZ Fit — 9H-Auto-Alignment Kit glass, suitable for models with covers. Price: ~700 rubles.

⚠️ Warning: Avoid glasses without a brand logo or with the words "For Xiaomi" - these are fakes that often have incorrect cutouts under the sensors.
How to check the compatibility of glass with a cover
One of the most common mistakes is to buy glass and case separately, without considering their compatibility, and if the glass is too thick and the case has high sides, you can click on the screen:
- 🌈 The effect of the “oil spot” (rainbow divorces due to pressure).
- 🔘 False pressing – the sensor works on its own.
- 📉 Sensitivity deterioration (more effort should be made for swipes).
To avoid problems, follow this algorithm:
Measure the thickness of the glass (optimally 0.2–0.33 mm) | Make sure the case has a cutout under the glass (not solid sides) | Check that the proximity sensor is not closed | Put the case on and check the screen response to pressing the edges | If you use a magnetic case, make sure that the glass does not contain metal particles-->
If you have already bought a case and glass separately, test their compatibility before the full installation:
- Place the glass on the screen without glue (just attach it).
- Put the case on and press the edges of the screen.
- If there are stains or sensor reacts poorly - look for another case or thinner glass.
💡
If you use a bumper case (without a back cover), choose glass with rounded edges of 3D - they cling less to pockets and peel less.
Step-by-step instructions for installation without bubbles
Even the most expensive glass is useless if you set it curved. The main enemies of the perfect glue are dust, humidity and uneven pressure.
- Preparation: 🧼 Wash your hands with soap and dry them. 📱 Turn off your smartphone and wipe the screen with microfiber cloth (complete with glass). 💨 Use a vacuum cleaner or tape to remove the micropyle (attach the tape to the screen and sharply tear off).
- Installation: 📏 Remove the protective film from the glass and gently attach it to the screen, starting at the bottom (where the charging connector is). 👆 Press the center of the glass and smoothly swipe your finger from the center to the edges, squeezing out the bubbles. 🔍 Check under the light - if there are small bubbles, gently tuck the glass and press again.
- Final steps: ⏳ Do not turn on the phone 1-2 hours – the glue should dry. 🚫 Do not use your smartphone in direct sunlight for 24 hours.
If you make a mistake and dust gets under the glass, do not try to move it - this will lead to microcracks. It is better to gently slap the edge and stick it again, after cleaning the screen with an alcohol napkin.

Frequent Mistakes and How to Avoid Them
Even experienced users sometimes face problems after installing the protective glass.-5 Mistakes and ways to prevent them:
- 🔴 The glass cracked immediately after installation. → Reason: edge bump or poor-quality material. Always check the certificate 9H seller.
- 🔴 The screen became "sticky" after a month → Reason: cheap oleophobic coating. Choose a glass labeled "Oleophobic Coating 2.0».
- 🔴 The proximity sensor is down. → Reason: Glass shut down the infrared port. Check the cutouts before you buy.
- 🔴 There were "rainbow" spots when pressed → Reason: conflict with the case. Use cases with a cut-out under the glass.
- 🔴 The glass unsticks itself. → Reason: greasy marks on the screen or poor-quality glue. Clean the screen with isopropyl alcohol before installing.
If you are faced with the problem of false presses after installing the glass, try calibrating the sensor:
- Go to Settings → About Phone → MIUI version (click 7 times to activate Developer Mode).
- Return to Settings → Additional → For developers → Calibration of the sensor.
- Follow the instructions on the screen.
💡
If the glass has started to crack for no apparent reason, check to see if moisture has fallen under it.Redmi Note 7 has no official water protection (IP-certificate), and the condensate can destroy the adhesive layer.
