Update Your iPhone to iOS12
Keeping devices updated is important for security and stability purposes. Another reason to update is because updates often come with new and cool features. Apple, recently released iOS12 and it comes with lots of cool new features you’ll want to check out. Get started by installing the update (it took my phone less than 20 minutes to complete).
Be sure your phone is plugged in and connected to wi-fi then Settings > General > Software Update. Tap Download and Install.
