Why the Redmi 8’s safety glass is not a luxury, but a necessity
The 6.22-inch Xiaomi Redmi 8 is covered with tempered glass from Gorilla Glass 5, but even it won’t save you from deep scratches or cracks when you fall. The protective glass isn’t just an accessory, it’s the only way to keep the screen tactile and prevent microcracks that eventually lead to a “web” when you press it. Unlike film, the glass doesn’t turn yellow, erase, or degrade the image quality.
Many Redmi 8 owners have a problem: after buying glass, only wipes and a dust collector are included, and it is not clear how to install it correctly. Sticker errors lead to bubbles, flaking edges or even cracks on the glass itself, which will help avoid typical errors and install protection perfectly the first time.
It's important to consider that Redmi 8 has rounded edges and a cutout for the front camera ("drop"). Poor glass may not match in shape, leaving unprotected areas, and we'll figure out how to choose the right model and prepare the surface to make the glass fall like a pour.
What kind of protective glass is suitable for Xiaomi Redmi 8: selection criteria
Not all glasses are equally useful. For Redmi 8, it's critical to choose a model that matches the exact size and form factor.
- 🔍 Thickness: optimally 0.2-0.33 mm Thin glass (0.15 mm) is worse to protect against impacts, and thick (0.5 mm)+) impair the sensitivity of the screen.
- 📏 Screen cover: should cover the entire work area, including rounded edges "3D Curved".
- 💎 Hardness: minimum 9H Mohs scale (standard for tempered glass) cheap options with 6H–8H scratch.
- 🎯 Cut under the camera: should exactly repeat the shape of the "drop" Redmi 8. Universal glass with a round neckline will not fit.
- 🧲 Oleophobic coating: reduces finger marks, and is tested with a simple test, swipe your finger across the glass: a quality coating leaves a barely noticeable trace.
Among the proven brands for Xiaomi Redmi 8 stand out:
- 🏆 Spigen Glas.tR EZ Fit – with a light installation system and an anti-bubble layer.
- 💰 AmFilm Ultra Glass – budget option with good protection (9H).
- 🛡️ Whitestone Dome Glass - Premium segment with liquid glue for perfect fit (requires) UV-lamp).
⚠️ Warning: Glasses labeled "Tempered Glass" without specifying hardness are often fakes. Check the reviews of a particular model before buying.

Step-by-step: how to glue glass on Xiaomi Redmi 8 without bubbles
Follow the algorithm in order. It takes 15 to 20 minutes to complete the process.
Step 1: Screen degreasing
Moisten your microfiber napkin with isopropyl alcohol (or use a wet wipe for your appliances). Rub the Redmi 8 screen in circular motions from center to edge, paying attention to:
- 🔄 The corners of the screen (there is the most dirt accumulating).
- 🕳️ Area around the camera cutout.
- 📱 The edges of the display (often left fingerprints).
After treatment with alcohol, wipe the screen with a dry microfiber to remove the stains.
Step 2: Dust removal
Turn on the lamp and direct the light at an angle of 30-45° All the dust particles will be visible as shadows. Use a tape or a dust collector:
- Press the tape to the screen (don’t press it hard!).
- Lift it at an angle - the dust will remain on the sticky side.
- Repeat 2-3 times, each time using a new piece of scotch.
💡
If the dust is not removed with tape, use an antistatic napkin or a spray of compressed air (sold in electronics stores).
Step 3: Testing the glass installation
Before removing the protective film from the glass, apply it to the Redmi 8 screen to:
- 📏 Check the match of cutouts (camera, speaker, sensors).
- 🔍 Make sure the glass doesn’t protrude beyond the edges of the display.
- 👆 Determine the optimal position for the sticker (usually from the top edge).
If the glass does not fall flat, check if there are any dust or grease particles on the screen.
Step 4: Glass sticker
Carefully remove the protective film with the adhesive side of the glass. Hold the glass behind the edges without touching the adhesive layer with your fingers.
- Line the glass at the top of the screen (where the camera is located).
- Lower it on the screen, starting at the top, and gradually press it against the display.
- Use a credit card or scraper to squeeze bubbles from the center to the edges.

Step 5: Finishing the processing
After the sticker:
- 🔦 Check the screen under light – all bubbles should disappear within 24 hours.
- 🚫 Do not turn on the phone for 10-15 minutes to get glue.
- 🧴 Apply a drop of silicone lubricant (if included) to the edges of the glass for additional sealing.
💡
If you have small bubbles around the edges after the sticker, don't try to squeeze them out, which can lead to detachment. They will disappear on their own in 12 to 24 hours.
Common Mistakes and How to Avoid Them
Even with a careful installation, Redmi 8 owners face problems.
| Problem. | Reason. | Decision |
|---|---|---|
| Bubble under glass | Dust or hair hit by glass | Remove the glass and re-clean the screen |
| The edges of the glass peel off | Bad degreasing or cheap glue | Warm up the edges with a hair dryer (not higher than 50)°C) and press |
| The glass cracked on the sticker. | Strong pressure or curved angle during installation | Use new glass, stick it on top of it. |
| The screen responds poorly to touch | Glass too thick (0.5 mm+) | Replace with glass 0.2-0.33 mm thick |
Pay special attention to the area around the notch under the camera. If the glass is not glued tightly in this place, over time, there will accumulate dust, and the camera will look dirty. UV-glue (sold in phone repair shops) and light up the place UV-lamp 10-15 seconds.
⚠️ Warning: If the glass starts to "go away" at the edges after 1-2 days, this is a sign of poor-quality glue. This glass will last no more than a month - it is better to immediately replace it with a model with a warranty (for example, Spigen or Whitestone).
How to take care of the protective glass on Xiaomi Redmi 8
The life of the glass depends not only on the quality of the installation, but also on the maintenance.
- 🧴 Cleaning: Use a microfiber wipe soaked in water or a special solution for the appliance. Do not use household chemicals (for example, Mr. Proper or Cillit Bang) - it destroys the oleophobic coating.
- 📱 Storage: Do not put your phone down on hard surfaces (table, asphalt). 9H-glass can crack from a spot impact.
- 🔥 Temperature: Avoid overheating (e.g. leaving your phone in the sun in your car) glue under glass at temperatures above 60°C loses its properties.
- 💧 Humidity: After raining or washing your hands, wipe the screen with a dry wipe – the water under the glass leads to detachment.
If the glass appeared deep scratches, do not try to polish them - it will spoil the oleophobic coating. The best option is to replace the glass (cost for Redmi 8 - from 200 to 800 rubles depending on the brand).
💡
To extend the life of the glass every 2-3 months apply to its surface a drop of silicone lubricant (from the kit for the care of equipment) and rub with microfiber, which will restore the slip and protection from finger marks.
What to do if the glass is cracked: emergency measures
Not only does cracked glass damage the appearance, it can also hurt your fingers with sharp edges.
- Lock the edges: Stick a thin tape around the perimeter of the cracks (for example, to seal the packages) so that the fragments do not crumble.
- Remove large fragments: Carefully tuck them in with a plastic card. Don't use tweezers - it can scratch the screen.
- Clean the screen: Wipe the surface with an alcohol napkin to remove the glue residue.
- Stick new glass: Repeat the installation process as described above.
If a crack appears on the Redmi 8 screen itself (not on the safety glass), don't delay repairs. OLED-Displays (and Redmi 8 is equipped with a IPS-If damaged, cracks spread quickly due to the flexible base, the cost of replacing the screen in the service is from 3000 to 5 000 rubles.
