If your iPhone begins to exhibit persistent issues, such as apps that crash or blank screens, you can perform a hard reset to return the device to factory default software and settings. Back up your apps, contacts, media and photos to iCloud before performing the master reset; after you reset the iPhone, you can restore the backups to replace your apps and files. If your iPhone is frozen or unresponsive, perform a soft reset using the hardware keys.
