The best way to apply tempered glass without bubbles is installation in a clean room (preferably in the bathroom after a shower), thorough degreasing of the screen, and evenly lowering the glass onto the display. Any bubbles should be gently pushed to the sides to ensure the adhesive adheres perfectly to the screen.
Why is it worth having glass on the screen?
The display is the most frequently damaged component of smartphones in Poland — according to the study Smart Barometer 2022 (Digital Care) about 75% of service events concern the screen. This is a real argument to proactively protect the display with glass or film and minimize the risk of costly repairs.
For new models, screen repair is an expense counted in hundreds or even ~2 thousand PLN. For example, an authorized Apple partner in Poland estimates the replacement of the iPhone 16 Pro display at 1,999 PLN (iPhone 16: 1,699 PLN; 16 Pro Max: 2,399 PLN)
In the case of Samsung Galaxy S25 Ultra an independent service provides an estimate: glass replacement 699 PLN, and full display replacement 1,049 PLN (prices are examples for one location in Poland).
The glass/film itself costs several dozen–~200 PLN in popular retail chains — often significantly less than one display repair.
Types of glass/film – quick comparison
| Type | What it is | Pros | Cons | When to choose |
|---|---|---|---|---|
| Tempered glass (case-friendly) | Rigid glass pane, shorter at the edges to avoid interfering with cases | Very good protection against impacts and scratches, “glass” glide, easy replacement | May crack on a strong fall | Universal protection for everyday use, with most cases |
| 3D / Full Cover glass | Shaped glass with a frame, full front coverage | Factory-like appearance, better edge closure | Requires good fitting to the case | When you care about full coverage and aesthetics |
| Hybrid glass (flex) | Glass-polymer laminate, more flexible than glass | Thinner, “hugs” the edges, lower risk of pane cracking | Somewhat weaker in falls vs classic glass | Screens with slight curvature, when tempered glass “sticks out” |
| Hydrogel film (wet application) | Flexible film, self-regenerates micro-scratches | Best fit (edge/curvatures), very thin | Weakest protection against hard impacts | Smartwatches, edge screens, priority: perfect adhesion |
| Matte glass/film (anti-reflective) | Matte finish reducing glare | Better readability in sunlight, pleasant “glide” under the stylus | Minimally lower image sharpness | Outdoor use, gaming/stylus |
| Privacy glass (privacy) | Layer narrowing the viewing angle | Protects content from prying eyes | Darker image, lower brightness | Work in transport/publicly |
| Antibacterial glass | Coating limiting bacterial growth | Greater surface hygiene | Does not increase drop resistance | Shared devices, high hygiene |
| Blue light filter glass | Filter for part of the blue light spectrum | Potentially greater eye comfort in the evening | Slight “warming” of the image | Long reading/work after dark |
Tip: if you use a case, choose glass “case-friendly” (does not end at the edge). For curved screens, the best options are 3D/Full Cover or hydrogel.
Instructions for installing tempered glass
1️⃣ Ensure a clean environment
Start the installation in the bathroom right after a shower – the steam will absorb the dust floating in the air, preventing dirt under the glass. This simple trick significantly improves the quality of the application.
2️⃣ Thoroughly clean the screen
Use the included alcohol-soaked cloth to remove greasy stains and dirt. Then polish the screen with a dry microfiber cloth so that the surface is perfectly smooth and shiny.
3️⃣ Precise fitting of the glass
Holding the glass by the edges, position it as evenly as possible. If a positioning frame is included in the set – be sure to use it to perfectly center the glass relative to the screen.
4️⃣ Applying the glass and pressing
Slowly lower the glass onto the display and let it adhere by itself. Then gently press it down, making circular motions for several seconds. This will ensure that the adhesive layer bonds well with the screen and maintains protection for a long time.
How to avoid air bubbles under the glass?
- Install the glass in a humid room, e.g., in the bathroom after a shower.
- Always use cleaning accessories from the set (cloths, dust stickers).
- Don’t rush – precision and patience guarantee the best result.

✅ General FAQ – tempered glass
🌟 Can you apply tempered glass yourself?
Yes, just clean the screen well, remove dust, and slowly lower the glass onto the display. In most cases, the installation is simple and takes a few minutes.
🌟 Can tempered glass be applied multiple times?
No. Once removed, it loses its adhesive layer and will not stick well to the screen.
🌟 How to remove tempered glass from the phone?
Gently pry up a corner with your nail or a plastic card and slowly lift the glass. Avoid sharp tools that may scratch the screen.
🌟 Will air bubbles under the glass disappear on their own?
Microscopic bubbles usually disappear after 24–48 hours. Larger bubbles should be pushed out with a card wrapped in a cloth.
🌟 Protective film or tempered glass – what to choose?
- Tempered glass provides better protection against impacts and falls.
- Film is thinner, more flexible, and works well on curved screens.
🌟 What types of protective glasses are there?
- classic tempered glass,
- hybrid glass (flexible, crack-resistant),
- privacy glass (protects privacy),
- antibacterial glass,
- matte and anti-reflective glass.
🌟 Does tempered glass worsen image or touch quality?
Good quality glasses are practically unnoticeable – they do not change touch sensitivity or image clarity.
🌟 Does tempered glass protect against screen cracking?
Yes – the glass absorbs the impact force, so in the event of a fall, the glass usually breaks instead of the phone screen.
🌟 How often should tempered glass be replaced?
It is worth replacing it when you notice deep scratches or cracks. Cracked glass no longer protects the screen effectively.
✅ FAQ about the service at Home Screen (Koszalin and surrounding areas)
🌟 Does Home Screen only apply glass to phones?
No – we also apply glass and films to tablets, smartwatches, and laptops.
🌟 Do you offer installation of hydrogel films?
Yes, we offer hydrogel films that perfectly fit curved screens thanks to wet installation.
🌟 Can I come right after buying a new phone?
Yes – many customers from Koszalin and surrounding areas choose to install glass or film on the day of purchasing the phone to immediately protect the screen.
🌟 Can I bring glass purchased from another store?
Yes – we also install glass and films purchased outside of Home Screen.
🌟 How long does it take to install glass or film?
