Ara, The Modular Phone

Google comes with new technology that is Ara, 

The Modular Phone 

In this phone specially designed for those who want new changes every day. In this phone, you can change every part of your phone like a camera, ram, cover, rom etc.

A modular smartphone in it's simplest form is a handset which can be easily upgraded by swapping individual components, or modules, in a plug and play style. It can be likened to upgrading a PC with a new motherboard, CPU or graphics card – out with the old, in with the new one component at a time. Project Ara was a modular smartphone project under development by Google. The project was originally headed by the Advanced Technology and Projects team within Motorola Mobility while it was a Google subsidiary. Google retained the ATAP group when selling Motorola to Lenovo, and it was placed under the stewardship of the Android development staff; Ara was later split off as an independent operation.
