Install iOS 11.3.1 to Fix These Issues
One of the big changes on board iOS 11.3.1 is a bug fix for iPhone 8 and iPhone 8 Plus users.

If you skipped iOS 11.3, your iOS 11.3.1 update comes with a substantial list of bug fixes for lingering iOS 11 issues. If you're dealing with any of these problems, and you skipped iOS 11.3, you'll want to consider downloading iOS 11.3.1 immediately.

If you skipped iOS 11.2.5, your iOS 11.3.1 update comes with bug fixes for several other issues thanks to iOS 11.2.5. These include:
If you skipped iOS 11.2, you'll get additional bug fixes with your version of iOS 11.3.1.
Apple's iOS 11.2 update was loaded up with bug fixes including one for the widespread calculator issue where quickly tapping 1 + 2 and the = sign gave the wrong result and a date bug that caused some devices to go into a crash loop.

If you own an iPhone 7 or an iPhone 7 Plus and you skipped iOS 11.2, iOS 11.2.1, iOS 11.2.2, iOS 11.2.5, and iOS 11.2.6, you probably want to install iOS 11.3.1 right now or in the near future. Here's why.
Apple's iOS 10.2.1 update, released in January of last year, prevented unexpected shutdowns on the iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, and iPhone SE.
iOS dynamically manages the instantaneous performance peaks, only when needed, to prevent the device from unexpectedly shutting down.
Apple's iOS 11.2 update extended the same capability to iPhone 7 and iPhone 7 Plus.
If you don't want unexpected shutdowns rendering your device unreliable or unusable, think about downloading iOS 11.3.1 today. Just know that it could come at the expense of your device's speed.
