If you’ve bought yourself a shiny new iPhone 7 this weekend then you might want to take a moment to get your ear close to the handset and make sure it’s not making any untoward hissing sounds.
A couple of people have reported the issue on Twitter and been offered replacement devices by Apple, so it looks like this could be a minor manufacturing defect affecting a small number of iPhones rather than a large scale problem that’s going to bring Apple to its knees.
Still, it takes a little of the shine off the iPhone 7 launch weekend. Yesterday we found out that the motionless home button in the new phones doesn’t work well with gloves.
