Install for These Small Enhancements
When Apple released the iOS 11 update it made some major changes to the software's UI. One of those changes was a rather confusing tweak to the Bluetooth and Wi-Fi toggles in Control Center.
In iOS 11.2, the company clarified how the Bluetooth and Wi-Fi toggles in Control Center work in iOS 11. Prior to iOS 11.2, the company had only outlined the changes in a support document.
As you can see in the screenshot here, tapping one of these toggles for the first time in iOS 11.2/iOS 11.2.1/iOS 11.2.2 brings up a couple of messages. These messages clarify why Bluetooth and Wi-Fi turn themselves back on after being disabled via the Control Center.
Once you install the iOS 11.2.2 update, you'll also get messages at the top of the screen that read "Disconnecting Nearby Wi-Fi Networks Until Tomorrow" or "Disconnecting Bluetooth Devices Until Tomorrow."
It's a smart little change and it's one that should clear up any confusion you had about the toggles moving forward.
Apple's also made a change to the iPhone X's Control Center gesture to make it more obvious.
If you're running iOS 11.2, iOS 11.2.1, or iOS 11.2.2 and you're on the iPhone X's lock screen, you'll see a small bar directly underneath the icons on the right side of the device's screen letting you know Control Center is there. It's a small tweak, but a nice touch, and a smart way to remind iPhone X users.
iOS 11.2-iOS 11.2.2 also includes improved video camera stabilization, support in Podcasts to automatically advance to the next episode from the same show, support in HealthKit for downhill snow sports distance as a data type, support for real-time text (RTT) phone calls for the deaf and hard of hearing, and improved stability in Calendar.
If any of those sound good to you, and you're currently running iOS 11.1.2 or below, consider downloading iOS 11.2.2.
