Tech Support TROUBLESHOOTING GUIDE Smartphones Smartphones have many components in common with computers, and like PCs, smartphones sometimes freeze, crash, or just run slowly. In this article, we’ll help you to fix a problematic smartphone. Unresponsive Phone You made need to power off and then restart your smartphone if it isn’t responding. Unresponsive Phone Power down the phone and then restart it. Most phones feature a but- ton you can hold for a given amount of time to bring up the power con- trols. For example, Apple iPhone owners can hold the Sleep/Wake button until a red slider appears, which you can slide to turn it off. Most Android-based phones bring up a shutdown menu after you hold the Power button for a few seconds. If your phone won’t respond to any key presses, you may have to remove the battery to restart the phone. Note that this isn’t an option for the iPhone, as it has a permanently at- tached battery. To do so, you’ll typi- cally need to remove the back panel of the case and pull out the battery. 68 May 2012 / www.smartcomputing.com
