Man's iPhone 4 back cover exploded after purchase, Apple claims it's not product-related and the phone was confiscated

Leading the trend of the times, more and more people are using this mobile phone, but the iPhone has become a shadow in the heart of Mr. Yuan from Hangzhou. "I originally wanted to buy one for my wife too, but now we definitely won't!" The reason for Mr. Yuan's helplessness is very simple: half a year ago, he bought an iPhone 4. Two weeks ago, while answering a call and talking for more than ten minutes, the back cover of the iPhone 4 suddenly exploded. Mr. Yuan showed the cracked phone to the reporter: the black frame of the iPhone 4 was severely deformed, the back cover was shattered like a spider web, but the screen was intact. The invoice showed that Mr. Yuan purchased the iPhone 4 on April 13th of this year.
