This Y2k-esque bug is not exactly the greatest thing that could happen to Apple right now; as MacWorld noted, iOS 11.1.2 was originally meant to fix a bug that turned off iPhone X screens in the cold, which itself followed a prior 11.1.1 update meant to take care of an auto-correct error. Tap Software Update, and the 11.2 update should be there waiting for you. If you have an iPhone 8 or an iPhone X as well as a wireless charger that supports 7.5W or more, your phone will now charge more quickly as Apple first limited wireless charging to 5W. Apple hasn't said anything about the bug, but has put up a new support page on the web. You can now send or receive money directly by using this app on the iOS device.
Tap to turn off Notifications. After you install it, you will need to turn your notifications back on.
iOS 11.2 is a must-upgrade due to the critical bug it fixes, but besides that and the arrival of Apple Pay for iMessage, it's largely a variety of smaller improvements to the system whose sum is greater than their individual parts. A few other tidbits are also included in this update. So, if you want to run a jailbroken software, you should settle for the 10.3.3 until there's an 11 stable version to try out.
To close down apps that are running in the background on most iPhones, you double-click the Home Button and then swiping up. The update also brings some system improvements to your device.
The new update is available on the iPhones 5s and later, iPads Air or mini 2 and later and the sixth generation iPod touch.
Additionally, the new iOS 11.2 update also brings new emojis to the camera app along with some updated emojis. This causes the device to heat up, which, in turn, causes a reset.
