Recently, the new folding smartphone Samsung Galaxy Z Flip went on sale and has already appeared on the desk of a famous blogger
What's wrong
Zach noticed that the display coverscratched by objects with a hardness of 2 on the Mohs scale, although usually modern smartphones only take materials with a hardness of 6-7. That is, the Galaxy Z Flip can be scratched even with a regular fingernail.
But at the presentation Samsung said thatThe flexible display is protected by a special ultra-thin glass coating, rather than plastic like other foldable devices. This coating is called Ultra Thin Glass and is a real breakthrough.
However, what is the innovation of this material if it scratches just like regular plastic coating? Zach suspected that Samsung had lied and that the Galaxy Z Flip's protective cover was also plastic.
The Verge decided to look into this issue and turned to Samsung for comments. The company did not want to communicate with journalists, but after a while one of the representatives explained:
Galaxy Z Flip features Infinity Flex Displaywith Samsung Ultra Thin Glass (UTG) that delivers a sleek, premium look and provides an immersive viewing experience. Samsung's first-of-its-kind UTG technology differentiates itself from others in its flagship Galaxy devices. Since the display is flexible, it should be handled with care. Also, the Galaxy Z Flip has a protective layer on top of the UTG, similar to the Galaxy Fold
It looks like Samsung is hinting that it could have been scratchedthat same second protective layer. But Zach believes that Samsung could use a hybrid plastic polymer (with microscopic pieces of glass mixed in), which is why it advertises this coating as “glass.”
In any case, with another test - for strength -The smartphone did the job. The blogger tried to bend it, as a result the metal frames came off a little, and in the end the glass on the back panel cracked. But the screen itself continued to work normally.
