But recently, many netizens reported that the glass of the nut Pro back cover just bought would explode!

According to the pictures taken by netizens, most of the explosions occurred at the logo of the back cover. The explosion occurred suddenly in normal use, but no one was injured.

Then we asked professionals about this problem,

professional: In fact, the reason is very simple. Because the logo on the back shell of the nut Pro is metal, there is not enough margin left when assembling the metal logo.
