They’re pretty dependable devices, but even today’s smartphones sometimes “hang” or “freeze”. No matter what you do, they refuse to respond when you touch their screens or press their keys and buttons.
Worry not. Smartphones are pretty easy to reset, or “reboot” to use the computing term, and the chances of losing your data in the process are practically nonexistent (you do regularly back up your smartphone, don’t you)?
To reboot an iPhone, hold the Home button and Sleep/Wake button together for ten seconds, or until the Apple logo appears. There isn’t too much more to this on Apple’s web site, but the site does offer other handy tips on how to handle problems on the phone.
Note that these instructions pertain to all of Apple’s iOS-based devices, including iPad and iPod Touch.
