What type of screen saver should I buy for my phone?

Since your smartphone is prone to drops and scratches, using a screen protector is best to avoid accidental scratches and cracks on your phone screen every day. But which of the different types on the market is the best screen protector for your phone? We've put together some helpful information you need to know about glass, gel, PET, and even liquid film screen protectors. Follow the lines below.


Types of phone screen protectors  

  • Polyethylene terephthalate (PET) films 

  • The term "PET" refers to a plastic polymer (polyethylene terephthalate). This material is typically found in items like refrigerant bottles and other food storage containers. PET films are usually the cheapest and also the lightest and thinnest. 

    This type of screen protector offers minimal protection against scratches but has the advantage of being less noticeable when applied to the screen.


  • Glass Screen Protector 

  • Without regenerative properties, the glass screen protector has the advantage that it is stiffer and thicker and therefore offers better protection. However, they are generally more visible precisely because of their greater thickness. 

    In addition, they prevent damage to the device panel but are quickly visible and easy to use and can even break if dropped, which can make many consumers want to change frequently. 

    There are also different types of screen protectors made of glass. You've probably heard of safety glass, 3D screen protectors, and even 10D. To understand how it works:

    • Safe glass: In the beginning, simple glass panels were more fragile. So much so that they have gradually been replaced by tempered glass, more common in the current market. This type of protection offers greater resistance to acute impacts. 
    • 3D, 4D, 5D, 6D or 10D glass: The difference between this type of screen protector is that it adapts better to the screens and the design of the phone. The curvature may vary depending on the model, and the entire protector practically imitates the front of the smartphone, including the "chin" and "forehead" parts, bringing these edges in the colours of the original design. This construction allows the film to be camouflaged. But wait: increasing numbers (3D, 4D, 5D) do not always mean a higher level of protection; While the promise is generally as follows, solidity varies by manufacturer and increasing the number can mean other benefits like carbon or metallic trim. These specifications vary by brand.

  • Hydrogel Screen Protector 

  • A new solution is the Hydrogel Screen Protector, which promises to absorb as much shock as a glass film, although it is thinner. They are also better for 2.5D glass displays and curved edges, but their edges can wear out faster. One downside is the price, which is generally higher than tempered glass films.


  • Liquid Film 

  • This type of screen protector caused controversy a few years ago for trying to give users a "placebo effect." There are several tests on YouTube showing that Liquid Nano fixed Film, the most popular brand to sell the product, used the protection of its own Gorilla Glass smartphone to sell non-existent scratch protection. 

    Since it is liquid and almost invisible when applied, it is also difficult to know when the product is completely spent and to estimate the breakdown time. Based on this information, it is better to stay away from this type of screen protector.


    After all, what is the best screen protector? 

    Well, it depends. When you have evaluated all of the above, you may have noticed that some solutions may work better depending on the type of display. For example, if you have a smartphone with a curved screen, a classic tempered glass film leaves the edges free, which can be fatal to the panel if it falls. In this case, you can choose a 3D glass model (4D, 5D, etc.) or a hydrogel screen protector. 

    If your phone has a flat screen, a safety glass screen protector may be the best option for protection and economy. It is less scratchy than hydrogel models. Ideally, you can compare the feeling of the two before making a decision. 

    The advantage of PET film and ordinary glass is the price. But remember: the cheapest ones can be expensive when it comes to protecting your mobile screen, that's why they are the least recommended.


    Note: The screen protector does not protect the back of the phone or the edges, so do your best to get a "good" case. I mean one with something like a raised lip above the screen.
