Starting Up and Shutting Down

One of the first things you’ll need to do is charge the battery. Android devices generally have a removable battery, which can easily be replaced. Apple devices have the battery sealed into the unit and it can only be replaced by an Apple service centre. Most Android devices are charged using a standard micro USB cable. Apple devices use a proprietary cable. Both types can be charged by connecting to the USB port of a computer or by connecting to a USB travel adaptor.

To insert the SIM card in an Android device, you’ll generally need to remove the rear cover to find the SIM slot .  Apple devices use micro-SIMs which are usually inserted into a slot in the casing. Many Android devices  allow you to add extra memory in the form of micro SD cards. It is not possible to add extra memory to Apple devices.

Most mobile devices offer a range of accessibility features to assist users with disabilities. Common features include:

  • Auto-rotate screen: Set the interface to rotate automatically when you rotate the device.
  • Call answering/ending: Answer calls by pressing specific keys
  • Screen timeout: Select the length of time that the device waits before turning off the display backlight.
  • TalkBack: provides voice feedback.
  • Negative colours: Reverse the display colours to improve visibility.
  • Font size: Change the font size for creating or showing items in applications.
  • Turn off all sounds: mute all device sounds.

A variety of options are available for locking or unlocking your device. These include:

  • Face detection unlock
  • Face and voice recognition unlock
  • Unlock pattern
  • Unlock PIN
  • Unlock password
Check your own mobile advice (or one you have access to). What options are available for locking / unlocking the device? Make a note of these.

Network options include Mobile networks (3G), WiFi, Bluetooth and NFC. Mobile network options include:

  • Use packet data: Set to use data connections on any mobile network.
  • Data roaming: Set to use data connections when you are roaming.
  • Access Point Names: Select an access point name (APN) for mobile networks.
  • Network mode: Select a network type.
  • Network operators: you can choose to search for and select a network or select the first available network.

You may need to enter a Network Key before you can access a WiFi network – the Network Administrator can provide you with this if required.

Some Android devices can read Near Field Communication (NFC) tags containing information about products. You can use this to make contactless payments and buy tickets for transportation or events. NFC is now widely used in Japan and is expected to become commonplace in Britain in the near future.
