The core or kernel provides access to various elements of the device hardware. It offers various services, such as the upper drivers or drivers for hardware, management processes, system files and access and management. The middleware is a set of modules that enable the existence of mobile applications. It is completely transparent to the user and provides key services such as messaging and communications engine, multimedia codecs, interpreters websites, device management and security.

The runtime application is an application manager and a set of open programmable interfaces in Mobile App Development. The user interfaces provide the user interaction and design of the visual presentation of the application. The services included are the graphics components (buttons, screens, lists, etc) And the frame interaction.

Apart from these layers, there is also a family of native phone applications which typically include menus, the label of phone numbers. As mobile phones grow in popularity, operating systems become more important. The market share of mobile operating systems in the second quarter of 2013 was as follows :

Android has the largest share since January 2011 with over half of the market, experienced an increasing and in only two years (2009 to early 2011) has become the most widely used mobile OS.

Mobile Device Management (MDM) is a type of software that enables monitoring and managing of mobile devices regardless of the network operator or service provider. Most let you install MDM applications, used for localization, tracking of equipment, backup, data reports and access devices, all remotely.

This type of applications has been widely accepted by the businesses, and its growth has been really high, this has been due largely to the popularity of smartphones. Agents maintain a connection to the server via USB, Wi-Fi, GPRS, 3G or other data transmission medium which allows the device to take control.

Mass Installation application: applications can be installed and run updates on multiple devices simultaneously and remotely controlling the connection type and the date of execution. Application selection: the MDM policies allow control over which applications can run devices, thus preventing users from running applications that are not productive.

Satellite tracking: through the use of GPS, we can find the location of one or more devices and the route maintained for a given period. File Synchronization: You can keep files synchronized with server devices.

Blocking of functions: a good MDM software enables control using device-specific functions can enable or disable the camera, microphone, USB, device access settings, among others. Cost control: some MDM can restrict the time phone calls or amount of data transmitted and even send alerts to take action or if the caps were exceeded.
