Module 8: Supporting Mobile Devices - CompTIA A+ Course

Overview

• Module Focus: Mobile devices and related technologies.
• Sections:
  1. Set up mobile devices and peripherals.
  2. Configure mobile device apps.
  3. Install and configure laptop hardware (feels out of place).
  4. Troubleshoot mobile device issues.

Section 1: Set Up Mobile Devices and Peripherals

Mobile Display Components

• Digitizer Functions:
  • Front layer of the device sensing touch (phones, tablets, some laptops and desktops).
  • Enables touch functions like scrolling, pinching, zooming.
• Glass Layer and Screen Protectors:
  • Essential to protect screens from brittleness and breaking.
  • Advisable to use covers and screen protectors.

Rotating and Removable Screens

• Rotating Screens:
  • Enabled through gyroscopes or accelerometers in devices.
  • Can be turned off when undesired (e.g., lying on your side).
• Removable Screens:
  • Some devices have removable screens, though rare.

Mobile Device Accessories

• Common accessories: headphones, microphones, speakers, touchpads, trackpads, drawing pads, cameras, webcams.
• Stylus (Touch Pins): Less common on phones, more on tablets or notes.

Wi-Fi Networking

• Enabling/Disabling:
  • Wi-Fi usually on by default, needs initial configuration.
• Airplane Mode:
  • Disables wireless communication to prevent interference.
• Antenna Placement:
  • Signal issues due to distance or physical obstructions.

Mobile Hotspots and Tethering

• Devices can broadcast their internet connection to others.
• Hotspot: Uses device’s data plan for connectivity.
• Tethering: Connected devices use USB, Wi-Fi, or Bluetooth.

Mobile Device Wired Connection Methods

• Laptops: Various ports (USB, HDMI, VGA, DisplayPort).
• Smartphones/Tablets: Primarily USB-C.

Bluetooth Wireless Connections

• Connects devices like headphones, cars, and speakers.
• Pairing process: Often requires PIN for security.

Near Field Communication (NFC)

• Used for contactless payments and data exchange.

Port Replicators and Docking Stations

• Port Replicators: Expand available ports (e.g., USB hubs).
• Docking Stations: Rare now; used to integrate laptops with desktop peripherals.

Section 2: Configure Mobile Device Apps

Mobile Apps

• Operating Systems: iOS (App Store), Android (Google Play Store), others like Huawei (App Gallery).
• Security: Be cautious with unknown apps.

Types of Data to Synchronize

• Contacts, calendar, mail, pictures, music, videos, documents.
• Synchronization Methods:
  • Cloud accounts (e.g., OneDrive, Google Drive).
  • Direct sync with laptops/desktops via USB or Wi-Fi.

Email Configuration Options

• Auto Discover: Simplifies email setup (e.g., for Gmail, Office 365).
• Manual Setup: Occasionally required for corporate or ISP emails.

Enterprise Mobility Management (MDM)

• Manage devices remotely (e.g., Microsoft InTune/Endpoint Configuration Manager).
• Features: authentication policies, compliance policies, remote device wipe.

Two Factor Authentication

• Enhances security through additional verification steps.

Section 3: Install and Configure Laptop Hardware

Laptop Disassembly

• Tools and Parts: Ensure correct tools are available.
• Organization: Use paper to keep track of screws and parts.

Battery Replacement

• Common Issues: Mostly related to AC adapters.
• Sealed designs often prevent battery replacement.

RAM and Adapter Replacements

• RAM: Typically SO-DIMMs; check compatibility and limits.
• Adapters: Can include Wi-Fi cards and others.

Section 4: Troubleshoot Mobile Device Issues

Power and Battery Issues

• Common Problems: Poor battery health, overheating, improper charging.
• Swollen Batteries: Must be replaced and disposed of properly.

Hardware Failure Issues

• Overheating: Often due to updates or usage.
• Liquid Damage: Turn off immediately, dry out thoroughly.
• Defective Ports: Can affect charging and peripheral connection.

Screen and Collaboration Issues

• Internal vs. External Display Issues: Use external screens for testing.
• Broken Screens: Require replacement.
• Digitizer Issues: Often caused by physical damage or dirt.
