It's a nifty feature for those who use Apple Pay all the time, but it can get annoying if you're not an Apple Pay fan. I tired of Apple Pay after my saved cards were repeatedly declined in New York City yellow cabs, and adding insult to injury, I kept activating Apple Pay by accident from my iPhone's lock screen.
As with Reachability, you can keep Apple Pay stowed by tweaking a simple setting. Tap Settings > Wallet & Apple Pay, then turn off the Double-Click Home Button setting. Once that's done, your Apple Pay cards will stay hidden unless you specifically launch the Wallet app or hold your iPhone next to an NFC payment terminal.
Summon Siri from the lock screen-or not
Helpful though she can be, Siri has a bad habit of appearing on my iPhone screen when I need her the least. Maybe something's up with the Home button on my iPhone 6, but Siri frequently pops up on my screen when I'm unlocking my iPhone, or when I'm trying to double-click.
If Siri keeps making unwanted appearances on your iPhone or iPad's lock screen, give this setting a try.
You can't change the default method of summoning Siri-pressing and holding the Home key-but you can keep her from appearing on your iPhone or iPad's lock screen.
Tap Settings > Touch ID & Passcode, then switch off the Siri option under the Allow Access When Locked setting.
