Have you ever wondered how manufacturers of mobile phone screen protectors make sure their products don't fail? If they're serious about their promises of quality, they put them through rigorous testing. Read on to find out which types of tests FIXED screen protectors most often undergo and how our ultra-durable screen protectors performed in the stress test. FIXED Armor glass . You will find detailed test results in the article.
It's thin and fragile at first glance, but in reality it can save your phone from disaster. However, to do this, a protective glass should be resistant to impacts and scratches, but also flexible and hard enough. And this can only be verified through standardized laboratory tests .
Why and which FIXED protective glasses do we test?
We do not include any of our protective glass in our offer without it having passed testing, because only thanks to thorough and standardized tests do we know that the goods meet the specified flexibility, hardness and other key parameters.
Individual glass parameters are tested directly by our developers, and in most cases, the products undergo five tests. We will introduce them to you in more detail in the following lines.
Do you want to know how to choose a protective glass for your phone and what common myths surround it? Read a separate article about it . For example, you will learn why hardness and flexibility are crucial or that it is important to be careful not to cover the camera and sensors with glass.
We test hardness, flexibility and light transmission
When people say "protective glass", most people probably first imagine its resistance to hard impacts, typically when a mobile phone falls to the ground. But that is just one of the parameters that we test for FIXED glass. What else must a product meet before we "release it on the shelves"?
Strength and elasticity test
This test is absolutely fundamental and it is hard to imagine that glass would go on sale without passing it.
The best way to test the strength parameters is to drop a hard object on them from a height, which simulates, for example, a phone falling from a height to the ground. We also test the flexibility, because the glass is placed on a hollow base and after a hard object falls, its level of flexibility is immediately apparent.
In the test, we use a 64g steel ball that is dropped onto the protective glass several times from a height. The goal is for the glass to withstand the ball's fall from the highest point possible .
Glass surface hardness test
Among other things, users expect a protective glass to be scratch-resistant at the first opportunity. Resistance to this damage is tested by a hardness test of the glass surface.
The test is carried out using scrapers, which the tester runs over the glass and determines its hardness according to the Mohs scale, which always ranges somewhere on a scale from 1 to 10. The higher the number, the higher the hardness and the better the scratch resistance .
Edge resistance test
How much can glass withstand when dropped on an edge? We test this using the edge resistance test, which is carried out by pressing a prism against the edge of the glass (pressure resistance is given in kilograms). The greater the impact the product can withstand, the better.
Light transmission test
Glass that does not allow light to pass through well would be of no use to the user. That is why one of the tests is dedicated to the passage of a light beam through the glass . It is given in percentages and again the higher the number, the better. The measurement is made with a device that shows how much of the transmitted light is captured on the other side of the glass.
The more light that passes through, the less it is reflected from the protective glass, so the protective glass practically does not affect the display. The highest possible light transmission is also crucial because reflected light (for example, outdoors in the sun) causes glare.
Surface treatment test
It is also important for protective glass that the user's finger glides over it with the same comfort as on a mobile phone display without glass and that it does not leave smudges and fingerprints . Therefore, in practice, glass cannot be used if it does not have a surface treatment - simply because the finger does not glide over it.
This is why glass protectors are equipped with a so-called oleophobic layer, which repels water and therefore glides better on the display.
And how does the glass surface treatment test work at FIXED? We do it by dropping distilled water and analyzing the resulting bubble under a microscope. The larger the bubble's edge angles, the more it is repelled by the glass, and the better the oleophobic layer.
For example, FIXED Armor glass even performs better than phone displays .
How did the extra durable FIXED Armor glass perform in the tests?
FIXED Armor is our flagship screen protector. With its extra durability, it can withstand almost anything and protect your screen many times better and longer than regular glass. We like facts over promises, so let's see how FIXED Armor performed in each of the five tests above and how it compared to standard glass.
FIXED Armor protective glass testing results
As you can see, FIXED Armor glass outperformed the standard one in all tests and in many ways even outperforms phone displays . Therefore, it will not only not affect the properties of your display, but even improve it.
Did you know that we also include a glass applicator in the package of FIXED Armor protective glass , which ensures that you install the glass on your mobile phone quickly, accurately, and without bubbles or dust particles on the display? Thanks to this, anyone can install the glass in no time.
