What to Check When Getting a Tempered Glass Screen Protector

One of the most popular mobile accessories is a tempered glass screen cover. 

This prevents the front panel from becoming scratched and decreases damage in the case of a collision, thanks to the protective surface. 

However, not all screen protectors are made equal. Other factors must be considered when looking for a screen protector to avoid degradation of sensor performance and information display.

Using the suggestions in this post, you should be able to find the best screen protector for your smartphone.

Look into the Material of Your Protector

Tempered Glass Screen Protector

It’s important to know that “protective glass” is tempered glass that has been hardened by heat or chemical processes. The protective surface is better able to withstand shocks and absorb mechanical energy after processing. Other screen protectors can’t match the level of protection provided by this particular add-on.

It’s also possible to apply a thin layer of gel-like liquid glass on the surface. In principle, the coating formed after solidification provides dependable protection, but in fact, the protective characteristics of the film are inferior to those of a typical one. As a result, using liquid glass is not suggested.

Conventional and hydrogel films are also available for purchase. With the use of hydrogel film, minor scratches are tightened, making the film last longer and smoothing out air bubbles in the event of an improper installation. However, the film’s protective qualities aren’t up to par with those of glass.

How Thick Should It Be?

Tempered glass screen protectors are available in three different thicknesses: 0.26 mm, 0.33 mm, and 0.5 mm. Protective characteristics are expected to increase with increasing thickness. This method is also used to absorb mechanical energy in the real world. Because of this, the glass’s wear resistance is 0.5 mm higher than the ones with lower thicknesses. The sensor’s sensitivity is unaffected by the thickness of the glass.

It’s important to remember that the glass frequently affects the ultrasonic fingerprint scanner. Unless you choose a manufacturer-certified glass device or an alternative with a notch for the fingerprint reading spot, the increased thickness interferes with fingerprint reading. First, the glass is more expensive, whereas the second option is less expensive but less appealing.

What Type of Finish Do You Want for the Surface?

There are tempered glass options with various finishes, including glossy, matte, and mixed.

The screen’s brightness and colour reproduction are unaffected by the screen’s glossy surface. It is also easier to see when something has been scratched because of the protective layer. The reflective nature of the surface can also cause glare.

It is less frequent to see frosted glass because of the brightness reduction that occurs once installed. Because of the increased graininess, viewing becomes more taxing on the eyes. Scratches and glare on the glass are less evident due to this.

Glossy and matte surfaces can both be found in combined-type glasses.

How Transparent Is It?

This setting influences the screen’s ability to transmit light through the glass. The more transparent the tempered glass screen protector, the less light it will retain. Transparency levels for most eyeglasses range from 92 to 95%. There are also 99%-transparent glasses on the market.

The most transparent glass should be used whenever possible. Otherwise, you’ll have to raise the system’s default brightness, which employs more power and drains the battery faster.


Not all tempered glass screen protectors are made equal. There are always other factors that should be considered when choosing a tempered glass screen protector. These tips should help you get started in the right direction.
