Samsung explained that the problem occurred when the user uncovered the special material shield covering the Galaxy Fold screen. But if it's that important, there's a controversy that there should have been enough guidance to misunderstand the screen shield.

Min Jae, a reporter at the core of the controversy, has pointed out.

OLED, organic light emitting diode (OLED) panel, is used on the screen of smartphone.

OLEDs are vulnerable to external shocks due to their nature and are vulnerable to oxygen and moisture. To protect them, the protective film made of tempered glass is finally covered on the screen.

Foldable blinds, which require repeated folding and unfolding, can not use glass on the screen, so instead they cover the screen with plastic film.

This film is like the glass of an existing smartphone.

[Ju, Byung-Kwon / Professor, Dept. of Electrical and Electronic Engineering, Korea University: From the substrate on the floor, 'coverglass' to 'cover plastic' is a single integrated display panel. If something is damaged, the operation of the device will be problematic.]

It is Samsung's analysis that the screen function was broken by removing this film which is like a part after all.

However, even if the film was not deliberately removed, it could be pointed out that the folded portion protrudes or the nails are easily scratched.

In the end, it is the first material that actually applies to smartphones, but it is pointed out that the user did not have enough notice in advance.

Samsung Electronics said it can replace the shield if there is a defect in use, but it should not be replaced by the user and should go through a service center.

In February, MWC, the global mobile exhibition, saw the wrinkled part of the screen when Huawei revealed its folder bubble.

It is not surprising that the controversy over the completeness of FolderBoop is growing due to excessive competition and containment by various companies trying to preoccupy the latest smartphone market.
