Project Ara under Google's Advanced Technology and Projects Group (ATAP) is currently working with more than 20 partners and aims to bring its modularized smartphone into commercial production in 2015, according to industry sources.

Makers in Taiwan's supply chain will play an important role to help realize the production of modularized phones, with related handset frames to be produced by Quanta Computer and connector boards by Foxconn Electronics, the sources noted.

Hardware partners will ship modularized parts, including displays, camera modules, CPUs, wireless modules, batteries, memory devices and cases, to consumers directly through Google's platform.

However, it remains to be seen if the modularized smartphones will be popular since most consumers are paying more attention to brands and handset designs, said the sources.
