Mobile devices can encounter problems ranging from unresponsive touchscreens to complete system lockout. This video explores common symptoms, such as slow performance (caused by excessive apps running) or overheating, and their solutions.
Mobile security troubleshooting

Video - 00:06:00

A lot of symptoms point to potential attacks on a mobile device, such as connection loss, power drain, slow data speeds, high resource utilization, and unintended connections. Others point at attacks that have already happened, such as leaked personal files, unauthorized account access, or unauthorized access to microphone or camera.
Mobile device security

Mobile device security starts with a lock screen but goes beyond with multifactor authentication (MFA) and remote find, lock, and wipe. Corporate environments use mobile device management (MDM) services for even more control over mobile devices.
Mobile synchronization

Synchronization keeps data up-to-date on each of your mobile devices and other connected devices. This video explores syncing to the desktop, automobile, cloud, and more.
Mobile devices and email

Video - 00:09:00

Corporate or ISP e-mail setup requires various configuration options, such as POP or IMAP for incoming mail and SMTP for outgoing mail. S/MIME was a way to encrypt e-mail attachments. Standard Google or Apple accounts set up with a simple username and password. This video explores these options.
Maintaining mobile devices

Video - 00:11:00

Mobile devices are surprisingly self-maintaining these days, but there are a few issues that come up occasionally. A big part of this is understanding the names and functions of certain settings unique to smartphones.
Virtual reality

Virtual reality enables you to experience remote or fanciful locations via computer. Augmented reality layers virtual elements onto a camera feed of the real world, making it easier to follow navigation instructions or chase fanciful monsters.
Touring iOS

Video - 00:07:00

iOS devices use a lot of gestures for accessing functions. The App Store offers all apps available for iOS. Settings enables you to change application permissions, account information, location services, and more.
Touring Android

Video - 00:10:00

Android devices are very customizable. The Google Play store offers shopping options for new applications (apps). Google accounts are mandatory. This video explores features specific to Android devices.
Mobile connections

Video - 00:10:00

Mobile devices connect to other devices via wired or wireless. Wired connections are used for power and data transfer. Wireless options include NFC, Bluetooth, infrared, or 802.11 (Wi-Fi). These connections are used for a variety of purposes, including file sharing, enhanced features (adding headphones, for example), and general networking.
What is a mobile device?

Video - 00:09:00

Mobile devices come in a variety of sealed forms and run mobile-specific operating systems. Devices include smartphones, tablets, wearables, e-readers, and more. OSes are Android, iOS, and a few others to a lesser extent. This video tours the common mobile devices.
Power management

Video - 00:11:00

Saving power is important, especially on mobile devices and laptops. Every CPU has a built-in feature to shut down different parts of a computer to reduce power needs. It’s up to the techs to make sure the power management settings are optimal for the users.
Touring your laptop display
