If you watch the video, the iPad Rehab spokesperson CLEARLY states that the problem is caused by BENDING the iPhone, for example by having the iPhone in your back pocket and sitting on it.
Smartphones, like desktop and notebook computers, HDTVs, tablets, and other electric devices are not meant to be bent. If they are bent, either purposely or by accident, damage can easily be done to the delicate electronic components inside the devices. Smartphones, because they are much smaller and thinner than larger computers or TVs, can be damaged much more easily.
In 2014 Consumer Reports did a 3-point pressure test on the iPhone 6 Plus, and they found that it took 90 pounds of pressure to bend the phone!!!
It is unfortunate that some people are neglectful of this fact, and (as in this case) many take absolutely no responsibility for the damage they have done to their own electronic devices. Lawyers love people such as those as clients, because win or lose, and no matter how frivolous a case they take on, it is money in their pockets.
Not everyone lacks the common sense to understand this, but is it REALLY necessary that each smartphone box come with a large sticker that says “Don’t apply enough pressure to this device to bend it, as that will cause damage”?
If this does get to court, with the evidence presented that the problem is caused by user damage to the iPhones, it will get tossed out!
