The security glass on Xiaomi is not just an accessory, but a necessary element to maintain the integrity of the screen. Even the most durable AMOLED or IPS displays in the flagships of Redmi, POCO or Mi are vulnerable to scratches, chips and cracks when falling. However, many users face problems when gluing: bubbles, dust under glass, displacement or poor adhesion. In this article, we will analyze the step-by-step process with the characteristics of different Xiaomi models, select tools and reveal the secrets of professionals.
It's important to understand that the gluing technology depends on the type of glass (2.5D, 3D, full screen), the phone model (for example, the Xiaomi 13 Ultra with a curved screen requires a special approach), and even indoor conditions. We tested the methods on the Redmi Note 12 Pro+, POCO F5 and Mi 11 Lite - and we are ready to share the conclusions. If you have never glued the glass yourself, don't worry: with our instructions, it will take no more than 20 minutes.
What kind of protective glass to choose for Xiaomi: types and features
The market offers dozens of glass options, but not all are suitable for a specific Xiaomi model.
- 🔹 Thickness: optimally 0.2-0.33 mm Thin glass (0.15 mm) is worse to protect against impacts, thick (0.5 mm)+) It can impair the sensitivity of the screen.
- 🔹 Form factor: 2.5D — flat glass with rounded edges (suitable for most Redmis). 3D/Full Cover – covers the entire screen, including curved edges (for Xiaomi) 12S Ultra, Mix Fold. Camera Lens - separate protection for the camera module (relevant to the camera module) POCO X5 Pro with protruding camera).
- 🔹 Durability: Look for markings 9H (maximum hardness on the Mohs scale. 6H It only protects against scratches.
- 🔹 Oleophobic coating: should be indicated on the package, without it, there will be greasy marks on the screen.
For models with a fingerprint sensor under the screen (for example, Xiaomi 13T Pro) choose glass with a notch under the sensor — otherwise the scanner will stop working. Also pay attention to the configuration: the set must be wet and dry wipes, dust collector and map for alignment.
Brands that are trustworthy:
- 🏆 Spigen - premium glass with a guarantee against chipping.
- 🥈 Nillkin - budget option with good adhesion.
- 🥉 AmFilm – the optimal price/quality ratio (suitable for the price/quality ratio) POCO M5).
Preparing Your Phone and Workplace: Why It Matters More Than It Seems
80 percent of the failures in gluing glass are due to poor preparation, and even a tiny speck of dust or a drop of moisture will ruin the result.
- Choose a room: ideally a bathroom after a hot shower (the steam precipitates the dust); alternatively, a closed room with wet cleaning.
- Prepare the tools: 🧴 Alcohol wipes (70% isopropyl alcohol). 🧻 Wilted tissue (microfibra). 💨 Vacuum cleaner or compressed air canister (to remove dust from speakers). 📏 Plastic card or scraper for alignment.
Clear the screen.
- Remove old glass or film with a scraper (if there is any glue residue, use 3M Scotch Tape).
- Wipe the screen with a wet wipe, then a dry microfiber towards the edges from the center.
- Blow the speakers and connectors with compressed air - dust from there can get on the screen.
Critical error: many people miss the degreasing stage, if there are traces of hand cream or fat on the screen, the glass will fall off after a day, use isopropyl alcohol (not vodka or cologne!).
💡
Before gluing, turn off the phone and take out the SIM card - so you will avoid accidental touching of the screen and getting dust from the tray.
Step-by-step: how to glue glass on Xiaomi without bubbles
Now, to the most critical stage, you're going to need patience and precision.
- Unpack the glass: Take the glass out of the package with the edges on it. Don't touch the adhesive side! Take the transport film off the front side (usually blue).
- Line up the glass: Gently apply the glass to the screen, combining the cutouts under the speaker and camera. Use a scotch fixer (if included) or pieces of paint tape to temporarily fix the glass.
Stick the glass together.
- Lift the glass by one edge and remove the protective film with the adhesive side.
- Instantly apply the glass back, starting at the top edge.
- Swipe the plastic card from center to edges, squeezing out bubbles.

Common Mistakes and How to Avoid Them
Even experienced users sometimes make mistakes, and here are the most common ones and ways to prevent them:
| Mistake. | Effects of consequences | How to fix it |
|---|---|---|
| Dust under glass | Visible points, worsening of adhesion | Remove the glass and re-clean. Use the dust collector. |
| Air bubbles | Unaesthetic appearance, possible detachment | Ride the bubbles to the edge. If it doesn't work, glue them. |
| Shifting of glass | Disparity of cutouts, incomplete protection | Use a positioning template or paint scotch. |
| Too much pressure. | Cracks on glass, damage to the oleophobic layer | Press moderately, just to level off. |
⚠️ Attention: if after gluing the glass started to stick around the edges after 1-2 days, this is a sign of poor adhesion. Chances are you used alcohol with additives (for example, medical 96% with oils) or did not degrease the screen.
Another common problem is the loss of sensitivity of the screen after gluing, which is due to:
- 🔘Too thick glass (thickness) > 0.33 mm).
- 🔘Poor quality of the glue layer (cheap glass).
- 🔘Incompatibility with the fingerprint sensor (for Xiaomi 13 Pro need a special cutout).

Features of sticking on popular Xiaomi models
Each Xiaomi series has unique nuances. Consider the most popular models:
Redmi Note 12 Pro+
A screen with 120 Hz and a fingerprint sensor under the display requires glass with:
- 📱 Cutout under the sensor (diameter 5-6 mm).
- 📱 0.25–0.3 mm thickness to maintain sensitivity.
- 📱 oleophobic coating AF+ (slippery).
POCO F5
Because AMOLED-In the high contrast screen, any defects in the gluing will be noticeable:
- 🔦 Use glass with UV-glue (such as Whitestone Dome) for perfect adhesion.
- 🔦 Sticking is carried out at a temperature of 20-25°C - the glue is grasped more evenly.
Xiaomi 13 Ultra
The curved screen and the large Leica camera complicate the process.
- 📸 Choose Full Cover 3D-flex-glass.
- 📸 Use a separate Nillkin Camera Lens glass to protect the camera.
- 📸 Sticking is carried out in two stages: first the main glass, then the protection of the camera.
💡
For models with LTPO AMOLED-screens (e.g. Xiaomi) 12S Pro) avoid glass with metallized layer - they can cause interference in the operation of sensors.
How to care for glass: extend the service life
Even the strongest glass will last longer if you follow the simple rules:
- 🧼 Cleaning: use only microfiber and 70% isopropyl alcohol. No abrasive wipes!
- 🚫 Avoid: Contact with keys/coins in one pocket; getting creams, hairspray or perfume; sudden temperature changes (do not leave your phone in the sun in your car).
- 🔄 Replacement: the oleophobic coating wears off after 6-12 months. If the screen becomes sticky, it's time to change the glass.
⚠️ Attention: if you use Xiaomi with a case, regularly check if it clings to the edges of the glass. This can lead to detachment).
To restore the oleophobic coating, you can use special sprays (for example, Nano-Coating), but their effect lasts 1-2 months. AF+ Or Oleophobic 3.0.
