How to put a protective glass on Xiaomi Redmi Note 7: a complete guide with life hacks

Why the Redmi Note 7’s safety glass is not a luxury, but a necessity

The 6.3-inch, FHD+ (2340×1080) Redmi Note 7 is covered with Gorilla Glass 5, but even it doesn’t save you from scratching your pocket keys or falling on asphalt. According to service centers, 68 percent of screen damage on this model is due to mechanical stresses that could prevent a high-quality protective glass, while 9 out of 10 users are gluing glass improperly, causing bubbles, dust under film or flaking edges a week later.

In this article, we've got a step-by-step algorithm for the Redmi Note 7 (front-facing cutout, rounded edges, sensor sensitivity), and a list of bugs that spoil the result. You'll learn how to choose the right coated glass, prepare the screen without slashes and fix it so it lasts for years. For clarity, we'll give you a comparative table of glass from different brands and a video instruction with typical beginners' shackles.

Spoiler: The most critical step is not the sticker itself, but the surface preparation, and even a microscopic speck of dust under the glass will turn into an annoying bubble in a month, and the wrong glue will reduce the sensitivity of the sensor by 20 to 30 percent, but about everything in order.

What kind of protective glass to choose for Redmi Note 7: comparison of the 5 best options

Not all glasses are equally useful. Cheap models from AliExpress for 100-150 rubles often have the wrong shape of the cutout for the camera (it can be too large or displaced), and their adhesive layer turns yellow after 3-4 months. We tested 5 popular options and made a table with key parameters:

🔹 If you drop your phone often, take Nillkin H.+ Pro or AmFilm Ultra Glass, which is thicker and better at absorbing shocks. Spigen Glas.tR is the best sensor for maximum sensitivity. EZ Fit, but it's harder to glue because of thinness.The original Xiaomi glass from the kit is a compromise option, but its oleophobic coating wears off faster than others.

⚠️ Warning: Glass with hardness below 9H They don't protect you from scratch with keys or coins, and models without oleophobic coatings will have to be wiped 2-3 times more often, because they quickly become covered with greasy marks.

Preparation for the sticker: what you need and how not to make mistakes

Before you start, check if you have everything you need.

• 🧴 Alcohol wipes (70-90% isopropyl alcohol) - 2-3 pieces.
• 🧻 Microfiber fabric without pile (suitable from the set for glasses).
• 💨 A compressed air cylinder or a small pear to remove dust.
• 📏 Scotch (paint or stationery) for fixing glass when sticker.
• 🔦 Bright lamp or flashlight to see dust on the screen.

🚫 What can't be done:

• 🧼 Use wet wipes or household chemicals (they leave divorces).
• 🌬 Blow on screen with your mouth – saliva contains fats that will worsen the grip.
• 🖐 Glue glass with your bare hands - only wearing gloves or holding the edges.

🔹 Professional advice: Turn off your phone before you stick it and let it cool to room temperature. The warm screen attracts dust, and the display on prevents you from seeing the contamination. Also remove the case, which can interfere with the alignment of the glass.

Step-by-step: how to glue glass without bubbles and dust

Now, to the most critical stage, follow the instructions in strict order, and skipping even one step can ruin the result.

Step 1. Screen cleaning

1. So, you can wet the whole screen with a liquor wipe, including the edges, and move from center to edge in circular motions.
2. Wait 10-15 seconds for the alcohol to evaporate – the screen should be completely dry.
3. Take the tape, glue it to the screen and abruptly tear it off (repeat 2-3 times) and remove the microparticles of dust.
4. Blow the screen with compressed air at an angle of 45°.

Step 2. Dust check

Turn on the flashlight and shine it on the screen at an angle. If you see the specks, repeat the scotch and air cleaning. Even one speck of dust under the glass in a month will turn into a noticeable bubble that will irritate every time you turn on the phone.

Step 3. Glass sticker.

1. Remove the protective film from the glue side of the glass (do not touch it with your fingers!).
2. Carefully apply the glass to the top of the screen (above the camera), combining the cutout.
3. Slowly lower the glass, pressing it from the center to the edges with a dry napkin.
4. If the glass is crooked, don't tear it off! Raise the edge and level it.

Step 4: Fixing

After the sticker, press hard on the glass for 20-30 seconds (you can use a credit card to press evenly). Then leave the phone for 1-2 hours - during which time the glue will finally grasp.

💡

If there are small bubbles under the glass, do not try to squeeze them out - they will disappear themselves in 12-24 hours. Large bubbles (more than 1 mm) indicate dust intake, in which case the glass will have to be reglased.

Common Mistakes and How to Avoid Them

Even if you follow the instructions, users often make 5 critical errors that spoil the results.

1. Bubbles around the edges of glass Cause: Not enough pressing or air entering the sticker. Solution: Use your credit card to squeeze air from the center to the edges. If the bubbles remain, warm them up with a hair dryer (not above 40°C) and press them again.
2. Dust under glass Cause: Bad screen cleaning or a sticker in a dusty room Solution: If there's not enough dust, leave it as it is (they won't hurt). If there's a lot, glue the glass.
3. The glass flakes off after a week Cause: Cheap glue or grease on the screen before the sticker. Solution: Buy a glass with silicone glue (like Spigen) and repeat the procedure.

⚠️ Note: If the sensor becomes less sensitive after the sticker (for example, the swipe does not work the first time), this means that the glass is too thick or glue is not compatible with the Redmi Note 7 screen. In this case, you will have to buy another glass (the optimal thickness is 0.26-0.33 mm).

How to prolong the life of protective glass: 7 rules of care

Even the most expensive glass won't last long if it's not properly cared for, and here's a list of rules to keep it in perfect condition:

• 🧴 Wipe the screen with only microfiber cloth (wet wipes destroy the oleophobic coating).
• 📵 Do not put the phone screen down on the table – so the glass scratches faster.
• 🔋 Avoid overheating (do not leave your phone in the sun or near the battery) – the glue may lose properties.
• 💧 Do not wash your phone with glued glass under running water – moisture will fall under the edges.

🔹 The secret from the masters: Every 2-3 months, apply a reductive oleophobic coating (for example, NanoMagic Screen Protector) to the glass, which will restore its original smoothness and protection from fingerprints.

If you follow these rules, quality glass will last 1.5-2 years without losing properties. For comparison, when used chaoticly, the same Nillkin H+ Pro will become obsolete after 6-8 months.

Video Instructions: Glass sticker on Redmi Note 7 with error analysis

For clarity, we recommend watching a video from the Xiaomi Repair channel, where the wizard shows the process of sticker on the Redmi Note 7 and disassembles typical schooling of beginners:

Key points from the video:

• 🎥 How to properly hold the glass when sticking (from 1:45).
• 🔍 Why you can't blow on the screen before the sticker (from 3:20).
• 🛠 How to fix curved glass without bubbles (from 5:10).

🔹 Note: The wizard uses Spigen Glas.tR in the video EZ Fit is one of the best Redmi Note 7 glasses in terms of price/quality. If you choose a different brand, the sticker process may be slightly different (for example, Nillkin has a different fixation system).

💡

The most common sticker mistake is haste. 80% of bubbles and dust under glass are caused by users skipping a thorough screen cleaning or gluing glass in a dusty room. Take 20-30 minutes to do the process and do it slowly.
