Apple has launched a program in the U.S. and Canada to replace the power/lock button of the iPhone 5. According to Apple, it discovered the button may fail on some devices manufactured through March 2013. Customers can use Apple's web site to determine if theirs is affected. If so, the phone can be sent directly to an Apple repair facility or taken to an Apple Store where it will be examined and then sent to a repair facility. Apple says the turn around time for repairs will be four to six days. In some cases, Apple may be able to provide a loaner device while the customer's iPhone is being repaired. Owners of the iPhone 5 can visit Apple's support site (link below) for more information.
Apple builds the best products. They don't malfunction. If anybody has a problem with the power button they are probably holding it wrong. If you hold an Android phone that way the power button stops working too.
