– Basic features of mobile operating

systems.

– Hardware differences in the mobile device.

Google Android and Apple iOS make up the vast majority of the mobile marketplace.

There are other players in this space, but they don’t

come close to the reach and influence of Apple and

Google in the mobile marketplace.



– Android.» Open source: the operating system can be modified within the

licensing agreement.

» Hardware: vendors can create their own Android devices.

» App sources: Google Play is the largest source of apps, but it is

not the only source.

– iOS.» Closed source: only available from Apple; can’t be modified.

» Hardware: only created by and available from Apple.

» App source: only available from Apple’s iTunes.

– Windows.» Closed source: only available from Microsoft.

» Hardware: vendors can create their own devices.

» App source: only available from the Microsoft App Store.


– Common operating system features.» Screen orientations: mobile devices can determine the

orientation of the screen (landscape or portrait).

• They do this through the use of an accelerometer and/or

gyroscope.

» GPS: mobile devices have global positioning system

capabilities, allowing the device to know where it is.

• Some apps use this information to improve their functionality.

» Geotracking: similar to GPS, but uses cell towers to track and

log device movement.

• Digital forensic specialists can use this information to track the

movement and history of a device.

• Some apps are available that make this easier.

» Screen calibration: not the issue that it once was, but the

touch screen may need to be recalibrated.

• Follow the device’s instructions to do so.

Mobile devices (tablets and phones) provide a smaller form factor for the user.

This smaller form factor has led to some differences

in the hardware of mobile devices when compared

with that of their lager cousins.



– No field serviceable parts.» Difficult to take apart without specialized equipment, with the

possible exception of some batteries.

» Most components are soldered in place (this is also becoming

more common on laptops).

» Not upgradeable; what you buy is what you get.

– Solid state drives.» Mobile devices never come with spinning hard disk drives.

– Touch interface.» Multi-touch: most mobile devices can sense when the user is

touching the screen in more than one place. This allows for

pinch and spread functions.

» Touch flow: most mobile devices can sense when a user has

moved a finger along a screen. This allows for dragging objects

and scrolling the screen type functions.


Android and iOS make up the majority of mobile devices. Android is open

source and open hardware, while iOS is closed across the board. Users

can load apps from appropriate sources to mobile devices. Screen

orientation and location services are built into the operating systems.

Topic

Basic features of mobile

operating systems.

Summary

The fact that there are no field serviceable parts and they are not

upgradeable help to define a mobile device. Additionally, all mobile devices

use SSD and have touch screens.

Hardware differences in the

mobile device.
