How Does It Work?

The Android device runs on an open source operating system and this means that it can be accessed by the public. This is one of the beneficial features of the device since many people are able to enjoy its features through the open source operating system. The aim of Google providing the code for the Android operating system to users and manufacturers may be more than just its application.

It may be argued that Google may not be very well positioned in the design and manufacturing of these devices and this means that it could be seeking for ways in which the design features could be explored by professional companies that have invested heavily in tablet design and manufacturing.

This could be a way of offering an opportunity to manufacturers who can improve the features of Androids by working on OS advancement and not coming up with their own systems, which could mean starting from the scratch. And because Android operating system is open source, it means that the manufacturers can focus on channelling their resources on the equipment or hardware and not concentrating on the software.
