In iOS 10, Apple made a small but fundamental change to the way touch ID users unlock their iPhone, iPad or iPod touch. If you’re tired of seeing “Press home to open” or “Press home to unlock” every time to you grab your phone, here’s how to switch it back to the way it was in iOS 9.
Change the iOS 10 Touch ID Behavior Back to iOS 9’s
To change the functionality back to the iOS 9 style you’re familiar with, simply launch the Settings app.
Navigate in the Settings menu to the “General” entry and select it.
Scroll down a ways until you see the entry for “Accessibility”. Select it.
In the Accessibility menu, again, scroll quite a bit until you see the entry for “Home Button” and select it.
In the Home Button menu you’ll find an entry, turned off by default in iOS 10, labeled “Rest Finger to Unlock”. Toggle it on, as seen below.
You can now press the Home button and, with a single press, both awake and unlock your iOS device.While we can appreciate why Apple made the change (to facilitate access to secure apps from the lock screen), we also appreciate they left a method in to go back to the iOS 9 way of doing things.
