One of the many new features you will find in your iPhone 6 is Reachability. For those of you who have not heard about it before, it is pretty simple. Double-tapping on the Touch ID/Home button will bring the screen down about, allowing users to reach the top apps a lot easier when they are only using one hand to navigate through the device.
As you can understand, this feature can be very useful but also very annoying, especially if you are as clumsy as I am. Although I would suggest giving it a try first, disabling Reachability is actually prety easy.
How to turn off Reachability in your iPhone 6
1. Open the Settings app.
2. Tap on the Accessibility menu.
3. Scroll down until you find the Reachability option.
4. Use the toggle button to disable the feature.
Although it is extremely rare, sometimes the feature will still work even after you have disabled it. If that happens, simply enable and disable the feature again and then restart your device to force the changes.
