Apple today released iOS 11.2, the second major update to the iOS 11 operating system available on the iPhone, iPad, and iPod touch. iOS 11.2 comes a month after iOS 11.1, the first major update to iOS 11, and it follows several other smaller bug fix updates.

The iOS 11.2 update is available on all eligible devices over-the-air in the Settings app. To access the update, go to Settings --> General --> Software Update. Eligible devices include the iPhone 5s and later, the iPad mini 2 and later, the iPad Air and later, and the 6th-generation iPod touch.

iOS 11.2, as a major 11.x update, brings several new features and important bug fixes. It introduces Apple Pay Cash , Apple's peer-to-peer payments service. Apple Pay Cash works through the Messages app and is designed to allow for quick person-to-person money transfers, like Square Cash or Venmo.

You can quickly and easily send and receive money through iMessage conversations with Apple Pay Cash. Cash is sent from a linked debit or credit card, while received cash is stored in an Apple Pay Cash card in the Wallet app and can be used for purchases or transferred to a bank account.

For the iPhone X, iPhone 8, and iPhone 8 Plus iOS 11.2 appears to introduce faster 7.5W wireless charging speeds through compatible Qi-based wireless charging accessories. At 7.5W charging speeds, the three new iPhones are able to charge faster wirelessly than with the standard 5W wired iPhone power adapter.

When it comes to the iPhone X interface, iOS 11.2 adds a small bar underneath the status bar icons located at the upper right side of the Lock screen, which is designed to make the location of the Control Center gesture more clear. On the iPhone X, Control Center is accessed by swiping down from the top of the device.

In Control Center on all devices, there are two new informational pop-ups that are displayed when using the Wi-Fi or Bluetooth toggles. These pop-ups explain that Bluetooth and Wi-Fi are disabled temporarily rather than permanently when accessed from the Control Center.

iOS 11.2 introduces a new Sports section in the dedicated TV app, which offers up access to live sports games through integration with the ESPN app. The Sports app can be accessed through a new "Sports" tab at the bottom of the app, and it offers up custom content based on team preferences and current sports seasons.

There are multiple bug fixes in the update, including a fix for an animation bug in the Calculator app that caused some numbers and symbols to be ignored when entered in rapid succession. The update removes the animations from the calculator app so calculations can be done quickly with no need to pause between entering numbers to obtain the correct result.

The update also addresses a date bug that caused continual crashing in iOS 11.1.2 after December 2. The problem was linked to local notifications, and according to a support document, it is fixed in iOS 11.2. iPhone and iPad users experiencing this bug should turn off notifications and then install iOS 11.2.

Other new features in iOS 11.2 include redesigned camera emojis and other emoji tweaks, a new loading animation for Live Photos effects, and Live wallpapers for the iPhone X. For developers, the update introduces a new feature that allows them to offer new customers discounted introductory pricing for auto-renewable subscriptions in the App Store. Full release notes for the update are available below:
