When you buy a mobile phone, you want to protect it to the maximum in order to prolong its useful life, so the first accessories you need when buying a mobile phone, whether new or second-hand, are the case and the screen protector.

In today’s article we tell you how important it is to choose the right screen protector, as well as the types of protectors that are available, to make your choice easier. Do not miss it!

How to choose a suitable screen protector 

A screen protector is a transparent layer of robust material that adheres to the screen of your mobile device to protect it. Its main purpose is to avoid cracks or scratches on the screen, which can arise from falls or bumps that occur during handling.

The screen is one of the most important and delicate elements of your mobile phone, and if it breaks, it can prevent the use of the device. In fact, screen breakage is one of the most common breakdowns dealt with by mobile technical services.

When choosing a screen protector for your mobile you should take into account the following criteria:

  1. Material of manufacture and thickness : some materials with which the protectors are made are polyethylene terephthalate (PET), Tempered Glass, InvisiGlass Ultra or UltraGlass. The thickness is usually between 0.2 and 0.45 millimeters. Keep in mind that the fact that a protector is thicker does not mean that it is more resistant, this depends on the composition and the manufacturer. You should consider the thickness at the level of usability and aesthetics, since the edges of a thick protector will be greater
  2. The type of coverage : Flat protector, which covers only the active area of ​​the screen or curved, which covers the maximum possible surface from edge to edge.
  3. Transparency level: Most screen protectors have a transparency level of over 95%. There are protectors with a multilayer structure, as well as others with anti-reflective surfaces, thanks to a matte coating, which makes it impossible to read from afar.

As we have mentioned, the ideal is to accompany the screen protector with a cover with thick edges, so that it also protects the device from side impacts. We tell you the most common types of screen protectors according to the characteristics mentioned.

Types of screen protectors

There are many types of screen protectors, since with the passage of time and the advancement of technology, the importance of protecting devices that are increasingly sophisticated has increased considerably. 

That is why some types of protectors are already part of the past, such as plastic protectors that, initially, were made of a very thin layer and their protection was not very effective. Another type, not so common, are nanoliquid protectors, a liquid solution that covers the entire screen of the phone, but with the passage of time, it decreases until it disappears.

Before mentioning the most common types, you should know that screen protectors are classified into two categories according to their materials:

  1. PET Protectors (Polyethylene Terephthalate): Semi-rigid and light plastic sheets that offer mainly anti-scratch protection.
  2. TPU protectors (Thermoplastic Polyurethane): They are moldable plastics that adapt well to curved surfaces and stand out for their elasticity. Within this type of protectors we can find those of gel or hydrogel.
  3. Tempered glass protectors: They are the most common and most resistant protectors, since their technology is based on the “multilayer” that consists of the union of several layers of materials.

The most common screen protectors that you can find on the market are the tempered glass one and the gel or hydrogel screen protector (TPU type), although you should keep in mind that both can have different varieties of models.

Tempered glass screen protector

The tempered glass screen protector is the most popular, since its resistance is very high thanks to the layers that make it up. Among them we find a layer of silicon, whose function is to absorb shocks and that these do not affect the glass of the device. Other layers are the oleophobic coating, with “anti-glare” properties, and finally, the tempered glass, which makes it a very resistant protector.

There are many types of tempered glass, among them we can find the mirror screen protector, which reflects everything as long as the screen is black, or the matte screen protector (or privacy screen protector), which only allows viewing the content of the screen in front of it and not from the sides.

Tempered glass has another advantage, and that is that it is very easy to find availability for all types of devices and, in addition, they are cheap. , we always recommend opting for recognized brands such as the Zagg screen protector , which stands out among all for its 25% extra protection against scratches.

In our mobile repair shops you can find all kinds of accessories for your phone, including Zagg’s InvisibleShield Glass + tempered glass protectors, a highly scratch-resistant protector with anti-shock technology and an easy-to-clean surface.

Gel or Hydrogel screen protector

It is another of the most common screen protectors, it stands out for its flexibility that allows it to adapt to all types of surfaces, even the back of the phone. This type of protector has properties based on fatty materials such as oil, which allow it to adhere perfectly to the screen, with a lumpy appearance.

Another of its features is that it protects the screen from scratches and bumps, and if these occur, they are limited to the area in which they occurred and do not spread throughout the panel.

The gel or hydrogel screen protector is a good option if you have a mobile with a curved screen , although its placement is not very simple and its price is not as cheap as that of tempered glass protectors.
