In this guide, we will show you step by step, how to apply glass on your phone – regardless of whether you chose tempered glass, hybrid glass, or a protective film.

With our tips, you will learn, how to prepare the screen, what to avoid, and what tools to use to achieve a factory-like finish. Ready? Let’s get started! 💪

Why is it worth applying protective glass on your phone?

The screen is the most vulnerable part of a smartphone. Even a small scratch can significantly reduce user comfort and the device’s value. Therefore, investing in screen protection is essential.

What do you gain from protective glass?

• Protection against scratches and cracks
• Shock absorption during a fall
• Lower repair costs (better to replace the glass than the entire screen)
• A clean, aesthetic appearance for a longer time

What are the types of screen protection? 🤔

🔸 Tempered glass (szkło hartowane)

• Stiff and thick (~0.3–0.5 mm)
• Hardness 9H
• Best protection against falls
• Requires precise installation – once applied, it is difficult to remove without damage

Examples:

✔️ Tempered glass 3mk HardGlass Max Lite iPhone 16 Pro Max
✔️ Tempered glass Hofi Glass Pro+ Samsung Galaxy S25 Black
✔️Tempered glass Ringke Easy Slide Google Pixel 9a Clear 

🔸 Hybrid glass

• Flexible, thinner (~0.2 mm)
• Does not shatter on impact, but also less resistant to scratches
• Easier to apply than tempered glass
• Ideal for curved screens

Examples:

✔️ Hybrid Glass GrizzGlass HybridGlass for Xiaomi 15
✔️ Hybrid Glass MyScreen HybridGLASS Apple Samsung Galaxy S24
✔️ Hybrid Glass 3MK FlexibleGlass Xiaomi 14T / 14T Pro

🔸 Protective film (PET / TPU / hydrogel)

• Ultra thin, almost invisible
• Protects against scratches and smudges
• Can be self-healing (hydrogel)
• Flexible – requires precise smoothing

Examples:

✔️ Matte film GrizzGlass PaperScreen for Samsung Galaxy Z Fold 6
✔️ Hydrogel film for screen Bizon Glass Hydrogel for Apple iPhone 14 Pro Max
✔️Protective film 3MK ARC+ Apple iPhone 16 Plus

Don’t know what to choose? See below a comparison of screen protection types.

What will you need?

Regardless of the type of protection, prepare:

✔️ Selected product (glass or film)
✔️ Cleaning kit (alcohol cloth + microfiber)
✔️ Dust stickers
✔️ Plastic card (e.g. bank card or included with the film)
✔️ Mounting frame (if included in the set)
✔️ Quiet place with good lighting (preferably bathroom after shower)

How to prepare the screen before applying?

1. Wash your hands – you will avoid streaks and grease
2. Turn off the phone – it will be easier to hold and clean
3. Clean the screen – first with alcohol, then with microfiber
4. Collect dust with the sticker – even invisible dust can cause bubbles

How to apply glass or film – step by step

🟢 For tempered glass

1. Fit the glass without peeling off the film
2. Peel off the protective adhesive layer
3. Slowly lower the glass from the center downwards
4. Smooth the surface by pushing the air to the edges
5. Any small bubbles will disappear after a few hours

🟡 For hybrid glass

1. Fit and adjust – you can gently correct the position
2. Remove the protective layer
3. Stick the glass, smoothing with a plastic card
4. If necessary – peel off a section, remove dust, and stick it back

---

🔵 For protective film

1. Usually, the film has several layers: number them according to the instructions
2. Stick the film starting from one edge
3. Use a card or spatula to slowly smooth the film towards the other side
4. Peel off the next layers according to the markings (e.g. ①, ②, ③)

💡 Hydrogel films have self-healing properties – minor scratches disappear on their own!

Is it worth using glasses with a mounting frame?

Yes! More and more brands are adding mounting frames, which make it easier to perfectly position the product. This is especially helpful with:

• curved screens
• small screens (e.g. iPhone SE)
• first installation

✅ Check e.g.:

• Tech-Protect Supreme Set Tempered Glass for Apple iPhone 16e Clear
• UGREEN SP629 Tempered Glass for Apple iPhone 16 Pro
• Tempered glass for the camera Spigen Optik.tr ez Fit Camera Protector Google Pixel 9 Pro XL Crystal Clear
• Tempered glass Spigen GLAS.tR ez Fit Samsung Galaxy A36 5G Clear
• Tempered glass Spigen GLAS.tR ez Fit HD Samsung Galaxy S25 Ultra Clear

Can you peel off and reapply the glass?

In the case of hybrid films and glasses – yes, but with caution. Tempered glass, once applied, loses its properties when removed and may get damaged.

Frequently Asked Questions

Does glass affect touch quality?
➡️ No, if you choose a high-quality product – the screen remains just as sensitive.

Can glass crack on its own?
➡️ No, but it can get scratched or damaged due to stress, e.g., with a strong case.

Does a protective glass work with a fingerprint reader?
➡️ It sometimes does – but there is no guarantee. Even if the manufacturer informs about compatibility with the in-screen reader (e.g., in Samsung Galaxy S24, Xiaomi 14T Pro, or OnePlus 12), the effectiveness of reading may vary depending on:

• the thickness of the glass,
• the type of adhesive used,
• the precision of installation,
• the quality of the scanner in the phone.

In some cases, re-adding the fingerprint after applying the glass can improve effectiveness. However, some phone and glass manufacturers note that 100% effectiveness cannot be guaranteed.

Does protective glass fit every case?
➡️ Not always. If you have a bulky case, it’s worth choosing «case friendly» glass that doesn’t reach the edges and won’t peel off.

Can you apply glass yourself without experience?
➡️ Yes! Especially if you choose glass with a mounting frame, e.g. 3mk HardGlass Max Lite or Grizz EasyFit. It literally takes 2–3 minutes.

What’s better – tempered glass, hybrid, or film?
➡️ It depends on your needs.

• Tempered glass = best protection against drops
• Hybrid = flexible and lightweight
• Film = thin, almost invisible, good for scratches

How much does good phone glass cost?
➡️ From 15 to 80 PLN, depending on the brand and model. Still cheaper than replacing a display for 1000 PLN+ 😉

What is a fingerprint reader?

How does a fingerprint reader work in smartphones?

A fingerprint reader in smartphones is a complex system that utilizes various technologies to identify unique fingerprint patterns. With sensors that scan the fingertip, the device is able to register and store an image of the user’s fingerprints. When the user attempts to unlock the phone, the scanner compares the scanned fingerprint with the stored pattern, allowing for quick and efficient unlocking of the phone.

What technologies does a fingerprint reader use?

Fingerprint readers use various technologies, including optical and capacitive. Optical technology uses light to create an image of the fingerprints, while capacitive technology works by measuring the difference in electrical capacitance between different areas of the fingertips. Recently, ultrasonic scanners have also gained popularity, which use sound waves to capture detailed information about the fingerprint, increasing recognition accuracy. What are the types of fingerprint readers?
