Why is it worth applying a screen protector 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 a screen protector?
- Protection against scratches and cracks
- Shock absorption during a fall
- Lower repair costs (it’s 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
- Rigid and thick (~0.3–0.5 mm)
- Hardness 9H
- Best protection against drops
- Requires precise installation – once applied, it’s 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 upon impact, but is also less resistant to scratches
- Easier to apply than tempered glass
- Ideal for curved screens
Examples:
✔️ GrizzGlass HybridGlass Hybrid Glass for Xiaomi 15
✔️ MyScreen HybridGLASS Apple Samsung Galaxy S24
✔️ 3MK FlexibleGlass Xiaomi 14T / 14T Pro
🔸 Protective film (PET / TPU / hydrogel)
- Ultra-thin, almost invisible
- Protects against scratches and streaks
- 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

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 one included with the film)
✔️ Mounting frame (if included in the set)
✔️ Quiet place with good lighting (preferably a bathroom after a shower)
How to prepare the screen before applying?
- Wash your hands – to avoid streaks and grease
- Turn off the phone – easier to hold and clean
- Clean the screen – first with alcohol, then with microfiber
- Collect dust with a sticker – even invisible dust can cause bubbles
How to apply glass or film – step by step
🟢 For tempered glass
- Fit the glass without peeling off the film
- Peel off the protective layer of the adhesive
- Slowly lower the glass from the center downwards
- Smooth the surface by pushing air to the edges
- Any small bubbles will disappear after a few hours
🟡 For hybrid glass
- Fit and adjust – you can gently correct the position
- Remove the protective layer
- Stick the glass, smoothing with a plastic card
- If necessary – peel off a section, remove dust, and stick it back
🔵 For protective film
- Usually, the film has several layers: number them according to the instructions
- Stick the film starting from one edge
- Use a card or spatula to slowly smooth the film to the other side
- 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 that make it easier to perfectly position the product. This is especially helpful for:
- 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 adhered, loses its properties upon removal 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 states compatibility with the in-screen reader (e.g., in Samsung Galaxy S24, Xiaomi 14T Pro, or OnePlus 12), the effectiveness of the reading may vary depending on:
- the thickness of the glass,
- the type of adhesive used,
- the precision of the installation,
- the quality of the scanner in the phone itself.
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 the 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 the 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+ 😉
