Screen protector or tempered glass — and do you need one with a phone case?

A phone case protects the back, corners, camera, and raised edge. But that palm-sized glass surface you look at hundreds of times a day is left exposed to pocket keys and grains of sand.

In this guide, we’ll go through the difference between tempered glass and protective film, why LEKA is a thin nano-PET film rather than thick glass, and whether you need a screen protector on top of a phone case at all. Short answer to the last one: usually yes — and not for the reason you think.

Short answer

Do I need a screen protector if I already have a phone case?

Yes, if you want full protection. A phone case and a screen protector protect two different things: the phone case handles the back, corners, and raised edge that keeps the display off the table — the screen protector handles what the case can’t reach: scratches on the glass surface itself. Together, they cover the whole phone. Separately, there’s always a gap.

The basics

What a screen protector actually does

A common misconception is that a screen protector is for drops. Most scratches, however, happen in much more ordinary ways: keys and coins in the same pocket, grains of sand on a table, or a backpack where your phone travels at the bottom.

Glass is hard, but not invincible. When your phone repeatedly meets materials harder than itself, the surface starts collecting hairline cracks and dull streaks. A screen protector has one simple job: it takes the hit so the display doesn’t have to. You can replace a worn film in a few minutes — replacing a scratched display can cost hundreds of euros.

Lastu character wondering which to choose, tempered glass or protective film Comparison

Tempered glass or protective film?

Two schools of thought, two different feels. Neither is wrong — the choice depends on what you value.

Feature Tempered glass screen protector Protective film (nano-PET)
Feel Firm, glass-like feel under your finger Preserves the original fingertip feel
Thickness Clearly adds thickness on top of the display Adds virtually no thickness
Edges Covers curved edges inconsistently, may crack on impact Thin and flexible — follows the edges, bends on impact
Installation Risk of air bubbles Easy to install, self-leveling
Small scratches Stay permanently visible Self-leveling surface — small scratches disappear
LEKA

LEKA — thin protection you barely feel

LEKA is a nano-PET protective film, not traditional tempered glass. It’s designed for exactly what most people want from their phone: as much protection as possible, with as little visible impact as possible. The film is so thin that it follows the display all the way to the edges — you use your phone like the film isn’t even there.

A self-leveling surface material means everyday little scratches fade from view instead of staying there permanently, catching the light. The package includes two films. You’ll find the details on the LEKA page.

FAQ

Frequently asked questions

Will my phone screen get scratched without protection?

Usually not from drops, but from everyday life: keys and coins in your pocket, grit on tabletops, and the bottom of your backpack wear down the glass over time. The screen protector takes those hits for you.

Is LEKA tempered glass?

No. LEKA is a thin nano-PET protective film that follows the screen and keeps the original touch feel. Compared with glass, it adds no thickness and won’t chip at the edges.

Do I need a screen protector if I already have a phone case?

Yes, if you want full protection. The phone case protects the back, corners, and raised edge; the screen protector protects the glass surface itself from scratches. They cover different areas.

Does LEKA fit iPhone 18 Pro and other new models?

It fits — LEKA is cut for each model and is available for the most popular models from iPhone 18 Pro to the Galaxy S26 series. Check your model on the LEKA page and add the film to the same order with your phone case.
