The iPhone 7 and iPhone 7 Plus come with a fancy new home button that drops the internal mechanics for a static version that's force sensitive instead - a similar approach to the one used on the trackpads for the most recent MacBooks.
Now that the phone is out on the streets, users have been playing around with the handset, and a new discovery has been made - the new-look home button only works with skin-on-iPhone contact.
If you're planning on wearing gloves this wintertime it looks like you might have to whip them off to get anywhere, although based on user testing being reported on the web, some gloves designed for touch interfaces are proving compatible.
Touch and go
The discovery was made by Brit Mike Hurley, who tweeted out his discovery with an appropriately unimpressed emoji.
Of course the home button isn't just used to unlock the phone - it gets you back to the start on iOS, lets you access Siri, activate multitasking and so on. Because you can no longer physically push the button down, you're out of luck with gloves.
And with iOS 10 ditching swipe to unlock, it's going to be a lot harder to get into your phone in the first place. Apple hasn't commented so far, but we'll let you know if it does.
