Protecting a smartphone right out of the box is something almost all users do. The current smartphones are more delicate and with a simple fall they can suffer very important aesthetic and functional damages. Today we talk about the most common protection in all smartphones: tempered glass or screen protector . It is one of the most sold accessories and it is very common to see it placed on almost all the mobile phones of friends or family. Today we dig a little into which one is more recommended and what you should take into account when buying a screen protector .
The 3 keys to screen protectors: hardness, transparency and fingerprints
If you are considering buying a screen protector for your mobile, you may have seen several that offer somewhat cumbersome information. Brands play with the marketing factor and also with terms that users do not usually know very well. Today we talk about the 3 keys when choosing a protective glass for your mobile .
Hardness in screen protector glasses
Almost all users confuse the most important term in screen protectors, hardness. This feature is displayed on screen savers with a number accompanied by an ax ( 9H ). It is the most important piece of information, but also the most misleading.
This one does not talk about resistance to bumps or drops, but to scratches . The number refers to the Mohs scale and offers a degree of resistance to scratches, that is, to how hard the glass is. But no, at no time does it talk about how resistant it is to falls or blows.
The scale goes from 1 to 9 and the most common is to find 9H crystals. If it is not 9H, it probably has a worse scratch resistance and the manufacturer decides not to include it in the information on the glass, so we do not recommend its purchase too much.
Again, we warn you that the figure speaks of scratch resistance and never shock resistance. Remember that it is a glass with the function of receiving blows, so if it breaks it will mean that it has saved the screen from an almost certain breakage.
If you have to buy a protector, make sure that it is a 9H or 10H glass, as you will have a glass that is quite resistant to daily scratches.
Transparency, another very important factor
You have bought a mobile phone and you want to enjoy its screen to the fullest, so you do not want a glass that reduces vision. In general, protective glasses are multi-layered and lack transparency. It is important that you pay attention to the percentage of transparency of the glass that you are going to buy and that it is above 95% .
Again, if the glass manufacturer does not talk about this factor, it may not be highly recommended to buy it. A glass with little transparency will spoil much of the image quality that your device offers.
Buy a protective glass with an oleophobic coating
Traces are another important factor. Many of these crystals are so cheap that they don’t offer too many treatments. The manufacturer may have spent the entire budget to make it sturdy and forget about fingerprints.
If you buy a protective glass, it is highly recommended that it have an oleophobic layer so that your fingerprints do not flood the front of the terminal and the experience is negative.
Very cheap protective glasses: run away from them
In stores like Amazon, all you have to do is do a simple search to find thousands of sellers that offer different types of tempered glass or screen protectors. Our recommendation is that you avoid extremely cheap crystals , as they probably do not offer everything that your box has.
A protective glass is responsible for protecting the screen of your smartphone and making the experience satisfactory while you use it. Don’t look to spend 2 euros / dollars on it and invest a little more.
A very cheap protective glass with 9H hardness, oleophobic coating, 98% transparency and high resistance sounds hard to believe. It depends a lot on the brand and the device, but our recommendation is that you opt for a recognized brand to ensure quality and compliance with all the factors that we have told you.
