Tired of scratches and fingerprints on your mobile screen? We all are, and we are always looking for a way to avoid them. Screen protectors are born from that need, with options such as tempered glass, hydrogel and more, each with its advantages and disadvantages.

Of those, there is a small group of protectors sold as self-healing and as the solution to all your problems. However, there is always the question of whether they really deliver on what was promised. Knowing this, we went to investigate and find out if self-repairing films for mobile screens They are used for something. Do you want to know the answer?

A screen protector that repairs itself?

the theme of self-healing surfaces is not a new thing, and on mobiles we have been listening to them since 2013 with the back of the LG G Flex. In 2017 it was the turn of the screens, thanks to a team from the University of California that developed a solution capable of conducting electricity.

That same year Motorola patented a much more drastic solution, with a glass screen capable of being repaired after heating it and without removing it from the mobile. And now, in 2020, Apple announced that its first folding mobile would have a self-repairing screen.

These self-healing surfaces, except for Motorola, are made of elastic polymers able to return to its original form after a scratch. Imagine a slime, that if you make a mark on it or deform it, after a short time it will be as if nothing had happened. It is the same principle, although the sheets for the mobile screen are much harder and also less “flexible”.

Do self-healing sheets really fix themselves?

Continuing with the previous idea, the self-healing sheets are made to return to their original shapebut how effective are they? Reading many user opinions and researching this type of protector, the truth is that the appreciation of them is very variable. There are those who hate them, some who love them, some who say that a specific brand is terrible and another is good (and vice versa).

Actually, you can find everything, but what you really need to know is the regenerative capacity of these sheets of protection. Going back to the slime example, what happens when you separate it totally into two pieces? They don’t come back together on their own, certain? The same thing happens with these protectors.

Self-healing screen protectors have a regenerative threshold, only much lower because they are made of more rigid polymers. Thus, if the scratch is very deep do not expect a miracle, because you will probably have cut the protector. In this case it will try to repair itself, but it will not be a perfect repair and there will be quite visible marks.

In the case of less deep scratches the thing improves a lot. Since the protector only “sinks” into the area of ​​the scratches, it will be able to repair the damage more easily and leave little visible or imperceptible marks.

However, in reality the deformation of the protector is still there, because flexibility and malleability come into play. When you deform something, it rarely stays the same again. and self-healing sheets also move by this principle.

They are useful? Yes, although don’t expect them to be a wonder that will fix all your problems, because they won’t make your screen indestructible. Although eye, there are some protectors to which you can apply heat they behave very very well.

Good self-healing screen protectors and bad protectors, why are there so many different opinions?

The issue of conflicting opinions about these protectors is linked to two factors. The first are buyer’s expectations, who sometimes buys one of these sheets thinking that it will solve his life, and it is not. When you buy something you have to know what you can expect from that product, its limitations and strengths.

The second factor is the manufacturer, as in everything, Some are very bad and some are very good.. What is the best you can do? Read the opinions of other buyers trying to be objective in your evaluation.

Directly related to the above is the price, but we will not include it as a quality factor because it is not always the case. Tests? The Poco F2 Pro and the OnePlus 8T, two phones that give a review of much more expensive ones.

Would we recommend them? If you know what you can expect from them, yes we would recommend them no problem. However, if you are only going to buy one because they sell it to you as the definitive solution, then better not. Here we leave you a very good option from a manufacturer with good opinions from its users:
