I have an iPhone 6 Plus which has somehow become bent. Apple have told me in writing that this is a technical hardware issue and the second of their four suggested options is to post on this forum. I am therefore doing what Apple suggested and assume that I can in fact post about this in here.
It is possible that there might be an issue with the overall design or a manufacturing fault in a limited number of iPhones and therefore I am doing as directed by Apple and posting on this forum.
I had problems with an iMac 27" screen in the past which users on the Apple iMac forum couldn't solve but did report as having the same fault. The thread became one of the most viewed on the Apple Forums and in the end I did get my iMac screen replaced FOC well out of warranty. Therefore highlighting an issue users are having may, or may not, highlight a wider number of occurrences.
When I first heard about people with bent iPhones my immediate reaction was that this was just an attempt to rubbish the phones near launch by a competitor, or was people not looking after their iPhones properly. However when it actually happened to me I got quite a shock and my whole attitude changed. Even more so when Apple has said they WILL NOT REPLACE ANY IPHONE 6 or 6 PLUS phones with ANY sort of bend damage. Don't be too quick to dismiss my problem. It may be your next problem, it was mine.
