Named the most convenient glass for a smartphone

MegaFon expert Zabelsky said that 3D is the most convenient glass for a smartphone

The most convenient glass for a smartphone is 3D, Vladlen Zabelsky, head of the accessories and portable equipment department at MegaFon, told RIA Novosti.

“High-quality protective glass has perfectly processed smooth edges and is always uniform in structure – without air bubbles, streaks and cloudy areas inside. The most practical and easy-to-use 3D glass, they completely cover the smartphone display, they are difficult to accidentally hook or peel off. 2D and 2.5D edges are not polished,” he explained.

Zabelsky added that, unlike a film that protects the screen from scratches, glass will save the smartphone display from shock or strong mechanical impact. He also recalled that glasses are produced taking into account the characteristics of a particular smartphone model – the shape of the display, size, rounded edges, the location of the speakers and the number of holes. “Of course, you can choose universal glass, but it will be less effective,” the  expert added.

According to Zabelsky, the strength of glass is measured on a 10-point Mohs scale, which determines the degree of surface resistance to scratches, cracks and chips. So, manufacturers indicate the strength of glass with the indicator “H” – hardness (strength, rigidity). “Today, the most common glass with a strength level of 9H. Such glasses reliably protect smartphones when dropped, and are also resistant to scratches,” he explained.

“The optimal glass thickness is from 0.3 to 0.5 mm. Users who tend to drop their smartphone often, as well as children who are still learning to take care of their gadgets, will use tempered glass with a thickness of 0.5 to 1 mm and a strength of 9H Products with such characteristics effectively protect the display even when dropped,” Zabelsky concluded and noted the need for periodic glass replacement: when air bubbles formed on the screen, a network of cracks appeared, the corners began to peel off or the sensor sensitivity decreased.
