It's a basic but effective fix for a variety of software issues that cause the iPhone to behave strangely at times. On the iPhone, a
forced restart works similarly to a soft reset or ordinary
reboot without impacting any of your important data saved on the internal memory. Here's how to force a reset on your new iPhone:
- Quickly press and release the Volume Up button.
- Quickly press and release the Volume Down button.
- Then, until the Apple logo shows, press and hold the Side or Power button.
Wait till your gadget has completely booted up before checking to see whether it is already stable.
