There was a time when the phone screens were made from glass that didn’t much differ from a usual glass. At that time, it was easy to scratch the phone screen with coins, sand, or other sharp items in your pocket. And the fall of the phone often ended with a broken screen. At this time, screen protectors were very relevant.

Especially popular have become Corning’s Gorilla Glass – tempered glasses that withstood a quite hard impact and saved your phone screen undamaged.

However, phone manufacturers made sure that new phone models would get more and more rugged screens. These days many phone manufacturers make phones with tempered glass. That means new expensive phones don’t need any additional screen protector. Although it is not necessary to use a screen protector, you can still do it.

Some people install a screen protector after purchasing a smartphone, while others prefer to use a phone without one. Let’s find out what the advantages and disadvantages of a screen protector are. This article will help you to understand if your smartphone needs a screen protector.

What advantages does using a screen protector offer?

Screen protection will absorb impacts such as scratches and bumps, increasing the likelihood that the smartphone screen will remain intact during prolonged use.

If your phone falls on concrete, asphalt, or other hard surfaces, a tempered glass screen protector will absorb a significant portion of the impact. Replacing a broken tempered glass screen protector is ten times cheaper than replacing your phone’s touch screen.

If you use a screen protector and case, it will allow your phone to look better even after years of use, so you can sell it more profitable than a phone with scratches, chips, and abrasions.

Most screen defenders have an oleophobic coating that makes your finger slide more easily and pleasantly over the surface. Also, greasy streaks and fingerprints on the smartphone screen are not so noticeable and easier to remove with a dry cloth. However, the oleophobic coating will be erased over time and will only be restored if the oleophobic liquid is applied again. If you’ve never used an oleophobic liquid or hydrogel screen protector, it may be better to try it on a tempered glass screen protector than directly on your smartphone touch screen.

The screen’s scratch protection is particularly useful for smartphones whose touchscreen has an ultrasonic fingerprint scanner built into it. Small scratches usually do not affect the scanner, but one or more deep scratches may cause the scanner to fail.

Disadvantages of using a screen protector

Some smartphones have a quality oleophobic coating that is superior to this coating in cheap screen protectors. In this case, the oleophobic coating is usually washed in 1-2 weeks, and it should be applied again.
Also, the installation of a protective glass or film automatically deprives the owner of the antibacterial coating. However, only two smartphones with antibacterial coating were produced. But maybe more of them will appear in the future.

Cheap screen protectors can affect the touchscreen sensitivity of your smartphone, which in rare cases, reduces responsiveness in applications. Your screen can also become darker and duller as the protective glass creates an additional barrier to light. There may also be minor changes in color rendering and glare.

Ultrasonic fingerprint scanners built into modern phones do not work with most screen protectors because the correct reading of a fingerprint requires direct contact with the touchscreen. This problem is solved by installing a screen protector from the smartphone manufacturer, but such a screen protector will be more expensive.

Conclusion

The article contains all the pros and cons that will help you decide whether you need a protective glass on your smartphone. Most tempered glasses, including cheap ones, rarely have a negative impact on sensor sensitivity, brightness, or color rendering. But it happens that the cheap glass is 1.5-2 mm narrower than the screen size of your smartphone, so once the tempered glass is installed, there are gaps along the edges of the screen.

A third-party screen protector can be a hassle for smartphone owners with an ultrasonic fingerprint scanner. If the ultrasound scanner does not work with your tempered glass, the problem can be solved by installing a manufacturer certified smartphone screen protector.
