Google is giving up on plans to build Project Ara, its long-promised modular smartphone. Reuters and Recode both report that the project is being shut down as the company moves to streamline its various hardware efforts.

The news comes as a bit of a shock, though it does follow multiple delays and setbacks for the experimental smartphone. Google originally promised to launch the device in Puerto Rico as an initial public test but canceled those plans last year. In May it announced a scaled-back version of Ara with fewer modular parts, which was supposed to be available for developers before the end of 2016.

The decision to kill Ara instead has been attributed to Rick Osterloh, who joined Google earlier this year to lead a unified hardware division. The former Motorola president apparently decided the modular phone was unlikely to succeed. Instead, the company will focus on other efforts like its Pixel lineup, Chromecast and the upcoming Google Home.

The search giant may be done spending money on Ara, but the project isn’t necessarily dead and gone. Google is apparently open to licensing the technology it developed to another company or simply finding a hardware maker willing to take over. So it’s possible we could see the modular smartphone make a comeback, just don’t expect it to happen anytime soon.
