If you're having a tough time double-clicking your iPhone or iPad's Home button fast enough, there's an easy way to slow things down.
If you don't have the split-second timing needed to double-click the Home button, there's a setting that'll help slow the pace a bit.
Tap Settings > General > Accessibility > Home Button, then pick a speed: Default (the fastest), Slow, or Slowest.
Each of the three options will blink repeatedly as you tap them, giving you an idea of how fast you'll have to double-click. Don't feel bad if you opt for the Slowest setting; that's what I did.
Turn off Reachability
Older iPhone models look puny compared to the jumbo-sized iPhone 6 and 6 Plus versions, but the smaller 3.5- and 4-inch iPhone screens have one advantage over their bigger brothers: You can access the entire thing with your thumb while holding the device in one hand.
iOS's Reachability feature can be summoned by accident.
That's why the bigger iPhone handsets (the iPhone 6 and later, except the iPhone SE) got Reachability, a feature that scoots the entire screen down to about the midpoint of the display, making it easier to reach the top of the interface with your thumb. You can activate Reachability by double-tapping, but not pressing, the Home button.
Now, Reachability is a considerate feature for those who use their iPhones with only one hand, but it's also easy to activate Reachability by mistake. Luckily, there's an easy way to disable Reachability if it's more trouble than it's worth. TapSettings > General > Accessibility, then switch off the Reachability setting.
Disable Apple Pay access from the lock screen
What's the point of Apple Pay if it isn't easier to get to than your wallet? Good question, and that's probably why you can use the Home button as an Apple Pay shortcut.
In just a few taps, you can turn off the Home button's ability to access Apple Pay from your iPhone or iPad's lock screen.
From your iPhone or iPad lock screen, you can simply double-click the Home button to make your Apple Pay debit and credit cards appear.
