One change in iOS 10 had a lot of people worked up. It wasn't a massive change to the operating system, and it certainly didn't make a big splash during Apple's keynote, but it has fundamentally changed the way some people use their iPhone and iPads.

Apple changed the way we unlock our iPhones. As of iOS 10, you have to press the Home button to unlock your phone, where before you could just rest your finger tip on the Home Button to unlock it using the fingerprint scanner, or Swipe to Unlock via your passcode if you had an older iPad or iPhone.

It's a small change, maybe, but when you have to retrain your fingers things can get frustrating.

Luckily it is easy to change it back to the way things were. To reactivate Rest Finger to Open, go to Settings > General > Accessibility > Home Button, then tap Rest Finger to Open.

Press to Unlock versus Slide to Unlock

How to unlock iPhone or iPad in iOS 10: iOS 9 and iOS 10

In iOS 9 (left), you were instructed to 'slide to unlock'. In iOS 10 (right), the instruction is 'Press Home to unlock' (or, occasionally, 'Press Home to open')

To be frank, you'll probably get used to the new way of doing things before long, and generally speaking this is a change that makes good sense: most people these days, and certainly the majority of people able to update their devices to iOS 10, have a Touch ID fingerprint scanner, and it's an altogether more efficient method to press the Home button while simultaneously having your fingerprint scanned.

But one aspect of the new system is different without adding any efficiency, and that's the fact that you have to actually press the Home button - you used to be able to get away with just lightly resting your fingertip on the scanner and letting Touch ID go to work. For sure, pressing a button isn't the most onerous of tasks, but when you've grown used to one particular method of unlocking a phone, even small changes can be annoying.

Even more annoying when you consider that the iPhone 7 doesn't actually have any moving parts in the Home Button so you aren't really pressing anything, you just push harder and Apple uses a vibration to make it feel like you pressed a button.

The good news is that you can turn off the requirement to press the Home button unlock your iPhone or iPad, and it's really easy if you know where to look for the setting.

Open the Settings app and go to General > Accessibility, then scroll down to the fourth group and tap Home Button. Toggle the bottom setting, Rest Finger to Open, so that it's enabled (green).

From now on you will be able to, in Apple's words, "Open iPhone with Touch ID, without having to press the Home button."

Bring back Swipe to Unlock in iOS 10

Now for the bad news. You can't bring back Swipe To Unlock, and we assume you won't even be able to. (Unless the backlash is huge. Or possibly someone comes up with a method via jailbreaking.)

If your reason for wanting to avoid using the Home Button is that your Home Button isn't working on your iPhone read this: How to fix a broken Home Button on the iPhone.
