For those who came in late, in 2014 multiple users reported that their brand new iPhone 6 and 6 Plus handsets were bending under pressure, such as when they were kept in a pocket. Apple never said anything about the problem and the Tame Apple Press insisted that the phone was as strong as the iPhone 5S.
According to documents found by Motherboard Apple's own tests showed that the iPhone 6 and iPhone 6 Plus were significantly more likely to bend than the iPhone 5S. Fortunately for Apple Bendgate went away, but in early 2016, many iPhone 6 and 6 Plus devices began to exhibit symptoms of “touch disease”. The phones’ screens would have a flickering gray bar at the top, and the touchscreen would stop working entirely or would work intermittently. Independent repair experts found that this was caused because the “Touch IC” chip, which translates a user’s touch into digital signals, became partially unseated from the phone’s logic board.
The information is contained in internal Apple documents filed under seal in a class action lawsuit that alleges Apple misled customers about touch disease.
The documents remain under seal, but US District Court judge Lucy Koh made some of the information from them public in a recent opinion in the case. The company found that the iPhone 6 is 3.3 times more likely to bend than the iPhone 5s, and the iPhone 6 Plus is 7.2 times more likely to bend than the iPhone 5s, according to the documents. Kohl noted that Apple described the bending as “expected behavior".
Koh wrote: "One of the major concerns Apple identified prior to launching the iPhones was that they were 'likely to bend more easily when compared to previous generations'".
