Google’s Modular Smartphone to Debut in Puerto Rico

Google’s vision of cheap modular smartphones made up of interchangeable pieces is getting closer to reality. The company showed off the latest prototype on Wednesday, and said that it will start selling its first modular phone in Puerto Rico later this year.

Google’s Advanced Technology and Projects (ATAP) group revealed the Spiral 2 on Wednesday during a crowded event for software developers at a Google office in Mountain View, California. It is a slim handset, its face dominated by a large display and a receiver module for phone calls that includes a light and proximity sensor on the front. On the back are eight different square and rectangular modules that snap into the phone’s slim metal skeleton to add different functions to the device.

The modules on the back include a camera, USB charger, Wi-Fi, and Bluetooth radios, and the device’s main processor. The display and receiver module on the front can also be swapped out. All the modules are held in place by magnets in the device’s frame.

Google says that this modular approach, which it calls Project Ara, will lead to inexpensive smartphones that can be customized and upgraded by users depending on their budget or personal requirements. You might want a camera with an optical zoom lens for a sightseeing trip, for instance, a pollution sensor to keep tabs on asthma, or just a simple phone with basic capabilities.

But the Spiral 2 prototype also shows how tricky it will be for Google to make a modular gadget successful. The latest device comes about nine months after ATAP unveiled the first Project Ara smartphone prototype, Spiral 1, at a similar conference (see “For Project Ara, It’s Module—Not App—Ideas Wanted”). That earlier device had Wi-Fi but no working cellular connection, and failed to work when presented to the crowd. Spiral 2 did manage to power up in public and showed Google’s Android operating system on its display.

The Spiral 2 prototype is slimmer and looks more polished than the previous version. But the handset is still far from being the flashy device with night vision and a slew of other modules imagined in a promotional Project Ara video shown at the conference. Google’s prototypes have yet to catch up to existing smartphones on features such as cellular data speeds, for example.

Ara Knaian, the chief mechanical engineer for the project and also its namesake, said one tricky problem now solved is that the modules of the first prototype would disconnect themselves when a person sat down on the phone. In the newer version, the slots for the modules on the endoskeleton are made more precisely.

“Definitely we’ve made a lot of progress,” he said. “Of course, there’s still plenty to do.”
