Now that users have had a couple of days with the iPhone 7, people are starting to get a better idea of how it works, and some have found a couple of unexpected surprises.

The first one has to do with the most important button on the iPhone 7: the Home button. Instead of a mechanical button that depresses when you push it, the iPhone 7's solid state (non-mechanical) Home button doesn't move and instead operates using software, providing haptic feedback to mimic the feel of a button push.

But we already knew that before the device went on sale. So what's the potential problem?

Because the new button (like the iPhone's screen) requires fingertip contact or some sort of capacitive contact to operate, many users will assume they'll need to, for example, take off their gloves to "virtually push" the Home button. However, capacitive touch gloves should solve this problem.

The potentially confusing issue was first pointed out by Relay FM co-founder Myke Hurley via Twitter.

So here's a thing.

Cover your iPhone 7 home button with material (like from a t-shirt) and try to click it.

And if you, for some reason, don't want to use the new capacitive touch Home button, there's also the option of using AssistiveTouch to bypass it altogether (h/t MacRumors).

The new button also makes executing a hard reset of the phone a trickier proposition. If you can't "press" the Home button in combination with the Sleep/Wake button (the process for previous models), how do you reset the device?

Answer: Apple has changed the reset process. To reset the iPhone 7 and 7 Plus, you press and hold down the Power button and then, while continuing to hold the Power button down, press the Lower Volume button. Hold both buttons for about five seconds and you'll trigger a reset.

The other issue is less clear in terms of solutions, as it deals with a mysterious hissing sound some users are reporting coming from the iPhone 7 and iPhone 7 Plus when the devices are undertaking processor-taxing functions.

Reports are still spotty at this point, but at least one user has posted a video demonstrating the hissing sound.

#Hissgate, my #iphone7 makes hiss and click sounds while gaming, but I have to keep it close to my head to hear. Anyone else?

The reports of the CPU making ‘hissing’ sound in the iPhone 7 are legit, but I have to put the phone against my ear to hear it.

But despite the reports of the hissing sound, none of those reports have indicated that the sound impairs the function of the device in any way.

Apple hasn't officially addressed the reports, but as recent news of a competing smartphone's problems indicate, if these are the biggest issues with the iPhone 7, Apple is still way ahead of the game.
