Restarting your iPhone may accomplish a variety of tasks. It not only clears and refreshes the internal memory, but also fixes tiny bugs that cause an app or gadget to malfunction. A device restart or soft reset can also fix network issues, particularly small ones. That being said, you should attempt it right now. To begin, here's how to perform a soft reset on the iPhone 8 Plus:

1. For a few seconds, press and hold the Side/Power button until the Slide to Power Off option displays.
2. To totally turn off the gadget, drag the slider.
3. Press and hold the Side/Power button for another 30 seconds, or until the Apple logo displays.
