Protective glass on a smartphone: types and features, which is better

The screen is the most fragile part of the smartphone. From what state the display is in, directly depends on whether it will be comfortable to work with the gadget. With a serious injury, the device may be impossible to use, because the sensor will stop responding to touch. Therefore, a protective glass is glued on the screen.

Types of protective glass for a smartphone

This is a durable coating of glass, which is made according to the shape of the screen. It is tightly glued to the display. If necessary, it can be easily removed. Protective glasses consist of several layers:

• A silicone layer adheres to the smartphone display, so that the coating does not slip on the base.
• The next layer gives strength and restrains the formation of a deep crack.
• Tempered glass is the toughest layer that takes the impact.
• Anti-reflective coating reduces the reflection of light rays, the image remains bright.
• Oleophobic coating protects against moisture. Fingerprints are less likely to remain on it.

The outer coating of protective glass for a smartphone can be matte or glossy. Matte glass slightly reduces the brightness. However, glare does not appear on it in sunny weather the way it does on a glossy surface. Fingerprints do not remain on the surface.

The durability of the safety glass determines the type of material from which the safety layer is made. Coatings made of talc, gypsum are the least strong. Apatite, orthoclase are of medium strength. Diamond safety glass is the strongest and most expensive.

Protective glass can be flat and slightly not reach the edges of the smartphone. Glass with rounded edges repeats the shape of the gadget and goes to the ends of the device.

The location of the camera on the glass can be designed in several ways:

• Round hole. The camera is not protected additionally. Periodically it needs to be wiped clean of debris.
• At the camera location, the glass is solid, but there is no adhesive backing. It may fog up, and over time, debris may get under the coating.
• The area between the protective glass and the surface of the smartphone is filled with transparent adhesive.

If you need the quality of selfies to be perfect, choose a protective glass with a slit for the camera. Then there will be no distortion if the camera is clear. When full-fledged protection of the camera area from impact is more important, you need a solid glass.

What protective glass for a smartphone is better

Pay attention to such indicators:

• The thickness of the glass comes from 0,1 to 1mm. It is better to choose in the range from 0,3 to 0,33 mm. When the coating is too thin, it has low protective properties. Thick glass is noticeable on the faucet and can reduce the sensitivity of the sensor.
• The type of edge protection glass for smartphone without frames is 2D with straight corners, 2.5D, 3D with rounded corners. In 2D glass, the adhesive is applied around the perimeter. After peeling off on the screen may remain traces of the connection. To avoid this effect, it is better if the protective glass is completely covered with glue.
• The presence of a frame. This is a practical decorative element of the protective glass. Over time, the edges of the coating can peel off a little, dust and small debris gets under it. Under a black or colored frame along the contour of the glass, it is not visible.

It is better to choose a multilayer glass from a reliable manufacturer. Even when it cracks from the impact, the screen is not damaged. It is important to take into account that not all injuries can be protected from all injuries to the gadget. If you drop the smartphone from a great height on the asphalt, even the strongest protective glass will not keep the display intact.
