An iPhone might display a blank screen, the touch screen may fail to respond, or an app gone awry may prevent the device from functioning properly. Getting your iPhone working again may require you to perform a series of troubleshooting steps to pinpoint and rectify the problem without damaging your data. After you’ve corrected the issue, you should update the iOS software as well as all of your apps to remedy buggy software and improve the reliability and performance of your iPhone. When general troubleshooting steps don’t resolve the issue, you can restore the device to its default settings using iTunes. Warnings Writer Bio
