iPhone 6S issue sees users struggling with 'burning hot' home button
Other problems with speakers and 3D Touch also being reported
It wouldn't be a proper iPhone launch without at least some semblance of a hardware controversy. And with the launch of the iPhone 6S and 6S Plus, the biggest early adopter gripe appears to be an issue with Touch ID.
First reported by 9to5Mac, users this year are reporting "burning-hot" home buttons, which some complain are too hot to leave their thumbs on for Touch ID authentication. The issue has done the rounds on Apple's support forum, with dozens of users complaining about it. Some users have expressed frustrations on Twitter, too.
However, the issue does seem to be software- rather than hardware-related. Advice on the forums suggests that holding down the home and power buttons for 10 seconds, resetting the phone, will fix the issue.
If the issue becomes bigger, Apple will likely issue a software fix with its next iOS 9 update. Until, then, however, the problem seems limited to a relatively small number of users.
That said, other problems with the new iPhones have also been reported. According to 9to5Mac, some iPhone 6S users suffer from an issue that sees their devices turn off of their own accord, despite having plenty of battery life. Another problem has been reported with speakers - some users say that notifications are played "super-loud", as if the speaker has been blown.
Finally, some users have reported problems with 3D Touch - particularly in relation to opening web links in Safari using a regular tap.
It's unlikely that we'll see another ‘Bendgate' emerge from any of these issues, which Apple will likely fix with software updates. However, it's worth bearing in mind that, when 13 million devices are sold over a single weekend, there's a decent chance that a few will be slightly faulty.
