Kelly Hodgkins, MacRumors:
As highlighted in a few reports shared in the MacRumors forums, a small but growing number of iPhone 6 Plus owners have reportedly bent their phones after carrying the devices in their pockets just days after launch. In one instance, a new iPhone 6 Plus was bent during a day of dancing, dining, and driving to a wedding.
Crap happens when you are not careful in the quest for super thin, super light, etc.
I think Apple made the wrong decision to make it so thin; Apple should have made it slightly thicker — which enhances rigidity — to make the camera flush with the body. And can you imagine how much more battery could have been shoved in there?
If you have an unbreakable habit of putting large smartphones in your pocket — front, back, does not matter — but are flexible enough to try Android, I highly recommend the LG G Flex.
