65. Common Solutions

66. Project Identify possible solutions for each problem

67. Summary Mobile device hardware has few field-repairable units. Mobile devices are often replaced instead of repaired due to the high cost of repairs. Mobile devices often contain proprietary parts that cannot be interchanged. Touchscreens are used instead of other input devices, such as mice and keyboards. SSDs are used in mobile devices because of their size, energy efficiency, and lack of noise. Open source software can be modified by anyone with little or no cost. Use only trusted content sources to avoid malware and unreliable content. Both Android and iOS have similar GUIs for using apps and other content. Mobile devices use sensors, such as GPS and accelerometers, to enhance their functionality.

68. Summary Network connections for mobile devices are made with cellular, Wi- Fi, and Bluetooth connections. Email accounts are closely tied to mobile devices and provide many different data synchronization services. Android devices use apps to synchronize data not automatically synchronized by Google. iOS devices use iTunes to synchronize data and other content. Passcode locks secure mobile devices. Remote backups can be performed to backup mobile device data to the Cloud. Remote lock or remote wipe are features to secure a mobile device that has been lost or stolen. Antivirus software is often used on mobile devices to prevent the transfer of malicious programs to other devices or computers.
