Step-by-step: how to stick the glass on Xiaomi Redmi Note 7 without bubbles

Xiaomi Redmi Note 7 It remains one of the most popular smartphones in the budget segment even years after its release. 6.3-inch IPS-resolution-screen 2340Γ—1080 It requires protection, especially if you're actively using the device, but many owners have problems with the safety glass, such as bubbles, dust under the film, improper positioning, or rapid detachment. In this article, we will analyze all the stages of the process - from the selection of glass to the final polishing, and also reveal the secret of professionals to remove microbubbles without re-installing.

It is important to understand that the Redmi Note 7 has a 2.5D-The screen is rounded, making glass harder to install than flat displays, and the touch layer is pressure sensitive, with improper installation leading to dead zones or false touches. We tested 5 different methods and selected the most effective ones that guarantee 100% fit even on the first try.

1. Which glass to choose for Xiaomi Redmi Note 7: comparison of types and brands

Not all security windows are the same. The Redmi Note 7 is critical to consider three things: thickness, coating, and case compatibility. Standard 0.2-0.3 mm glass windows are suitable for most tasks, but if you drop your phone often, consider the 0.5 mm reinforced layer options. However, remember that too thick glass can impair sensor sensitivity and interfere with the use of high-sided cases.

Among the proven brands stand out:

  • πŸ”Ή Spigen Glas.tR EZ Fit – self-centered glass with flexible edges, ideal for 2.5D-And there's a frame installer that's designed to eliminate bias.
  • πŸ”Ή Nillkin H+ Pro – Japanese glass with oleophobic coating that repels fingerprints 30% more efficiently than standard versions.
  • πŸ”Ή AmFilm Ultra Glass – budget version with a 9H-Hardness, but requires careful installation due to lack of frames.
  • πŸ”Ή Belkin Invisiglass is a premium solution with a lifetime guarantee against chipping, but the price is 2-3 times higher than its counterparts.

Pay attention to the size of the glass: for Redmi Note 7 fits the format 158.6 Γ— 76.4 mm with a cutout for the speaker and front camera. Avoid universal glasses - they rarely match the cutouts and spoil the appearance. Also check if there is an alcohol wipe and a dust collector (sticky tape for cleaning). If not, buy them separately.

2. Workplace and tools preparation: what is needed for the perfect installation

A successful installation is 80% pre-prepared.

  • πŸ“± Clean, dry room - ideal bathroom after a hot shower (the steam settles on dust, reducing its amount in the air).
  • πŸ”¦ Bright light source – a desk lamp or flashlight for checking bubbles.
  • 🧴 Isopropyl alcohol (70% or higher) to degrease the screen. Don't use vodka or cologne.
  • 🧻 Microfiber wipe (not paper!) - for final polishing.
  • 🧲 Scotch or paint tape – to fix dust on the edges of the screen.

Also, prepare a card or a mediator to help drive out bubbles. If you have a glass with a locker frame (like Spigen), you don't need additional tools. Before you start, turn off your smartphone, which will allow you to see the pollution on the screen better and avoid accidental touches.

  1. Clean the screen. Put 5-6 drops of alcohol on the screen and evenly spread with a microfiber wipe. Movements should be circular, from center to edge. Repeat the procedure 2 times.
  2. Dust removal. Use a dust collector (sticky tape) or scotch to collect the smallest particles, run them around the edges of the screen and above the speaker.
  3. Positioning glass. If you have a glass frame, put it on the screen and align it with the speaker and the camera. The glass will fall into place. If you don't have a frame, gently apply the glass at a 30Β° angle starting at the top, and gradually lower it.

4. How to remove bubbles after installation: professional life hacks

If you have small bubbles left after installation, do not rush to reglaze the glass. In many cases, they can be eliminated without dismantling:

  • πŸ’¨ Heat the bubble with a hair dryer at minimum power (distance 10-15 cm) for 10-15 seconds, then press the glass with your finger. The heat will soften the glue, and the bubble will "spread out".
  • πŸ“¦ Vacuum method: Put your smartphone in a plastic bag, squeeze out the air and leave it for 1 hour.
  • 🧴 Oil method. Apply 1 drop of silicone oil (from the appliance care kit) on the bubble and gently cook with a microfiber wipe.

Critical nuance: these methods only work for bubbles up to 2 mm in size. Large defects or dust under the glass require a complete reinstallation. Also, do not use needles or toothpicks to puncture the bubbles - this will damage the oleophobic coating.

If the bubbles appear a week after installation, it's a sign of poor-quality glue, in which case the glass will have to be replaced, you can't smooth out these defects.

5. Frequent problems and how to avoid them

Even with a careful installation, there can be unexpected difficulties.

Problem 1: Glass is removed at the edges in 1-2 days.

It's because of poor adhesion of the glue or moisture.

  • Use glass with UV-glue (they are fixed under an ultraviolet lamp).
  • Avoid washing your hands before installation – moisture from your fingers can get under the glass.

Problem 2: Sensitivity of the sensor is reduced.

The culprit is too thick glass (more than 0.5 mm) or incorrect positioning.

  • Does the glass cutout match the touch buttons (if you have them on your model)?
  • Does the glass press on the edges of the screen (relevant for full-coated glass).

⚠️ Warning: If the glass is pressed (bends and returns) after installation, it is a sign of insufficient pressure when fixing. Remove the glass and repeat the installation, pressing the center more strongly.

6. Care behind glass: how to extend its service life

The safety glass will last longer if you follow the following simple rules:

  • 🧼 Clean. Use special wipes for glass (no alcohol!) or microfiber dipped in distilled water. Conventional wet wipes destroy the oleophobic coating.
  • πŸ“΅ Storage. Don't put your smartphone down on abrasive surfaces (sand, concrete, metal). 9H-glass is scratched by microparticles.
  • πŸ”‹ Avoid wireless charging with metal surfaces - they can cause overheating and glass detachment.
  • 🧀 Covers: Use cases with raised edges (0.5-1 mm) to protect the glass when falling.

The average lifespan of quality glass is 12 to 18 months, and if you notice that the oleophobic coating has stopped repelling fat and there are microcracks on the glass, you should replace it, and remember, even a small crack can spread to the screen when you hit it.

Regular glass replacement (once every 1-1.5 years) is cheaper than repairing a cracked screen Xiaomi Redmi Note 7, which costs 5-7 thousand rubles.

7. Safety glass alternatives: when it is not suitable

If you are not prepared to tolerate sensor degradation or visual distortion (rainbow effect on some glass), consider alternatives:

  • πŸ›‘οΈ Liquid glass, applied as a coating and invisible on the screen, Minus - lasts 6-12 months and does not protect against heavy impacts.
  • πŸ“„ Hybrid films combine the properties of glass and film: thin (0.1 mm), but with hardness. 6H. Suitable for high-sided covers.
  • πŸ”„ Self-healing films. Small scratches tighten in 24 hours. Best for those who change protections frequently.

For the Redmi Note 7, liquid glass is a controversial choice: its 2.5D-It's hard to evenly cover the screen, so if you're willing, use professional applicator kits. UV-lamp (e.g. Cima Nano or GlassSkin).

FAQ: Answers to Frequent Questions

Can I paste glass on Xiaomi Redmi Note 7 without a frame-fixer?
Yes, but it takes a lot of skill. The key is to align the glass correctly across the speaker and camera before you finally lock it, use a sticky tape to temporarily fix the top edge so that the glass doesn't move when you lower it, and dry-mount it, you can apply the glass without removing the protective film, check the positioning, and then carefully remove the film and fix it.
How much does it cost to replace the glass in the service center for the Redmi Note 7?
The cost depends on the type of glass: Standard (0.3 mm, 9H) - 500-800 rubles. Premium (0.5 mm, with oleophobic coating) - 1000-1500 rubles. Full coverage (with rounded edges) - 1500-2000 rubles. The cost usually includes a warranty of 1-3 months for detachment. However, services often use universal glasses that may not ideally fit the cutouts of the Redmi Note 7.
What if the glass is broken but the screen is full?
If the crack is not deep (not felt with your finger), you can leave the glass until you replace it, but: Close the crack with transparent tape to avoid dust. Avoid pressuring the damaged area - this can lead to the crack spreading. Do not use alcohol-containing cleaning agents - they will penetrate the crack and will wash the glue. Replace the glass for 1-2 weeks, as the crack impairs the protection of the screen from impacts.
Is the glass from the Redmi Note 8 on the Redmi Note 7 right?
No, despite the similar screen size (6.3), these models have different notches for the speaker and camera: Redmi Note 7 has a drop-shaped cutout (width ~4 mm). Redmi Note 8 is a miniature hole (diameter ~2.5 mm). Glass from the Note 8 will close the front camera Note 7, making it impossible to use a selfie camera and face recognition.
Can I put a glass on an already cracked screen?
Technically, yes, but it's not recommended for three reasons: Cracks on the screen have sharp edges that can cut through the protective glass when pressed; glass glue can leak into the cracks, which will complicate subsequent repair of the screen; glass will not fully protect the damaged screen from further destruction; The best option is to replace the screen first, and then install a new glass.
