Techopedia explains Modular Phone
In general, Google's Advanced Technology and Projects (ATAP) group, which, according to some experts, emerged from DARPA, is behind the development of the modular phone and provides specifications for how this type of phone would work.
Developers working on modular phones are looking at the internal technology, for example, the passive components that will provide the different kinds of functionality. At the same time, designers are also looking at the aesthetic aspect of the phone so they could design the modules well, so as not to make the phones look overly clunky.
Modular phones are still under development, but some are being presented at various technology websites as they evolve.
