As if a Lego-like customizable phone made of blocks wasn’t enough: Thanks to a modified version of Android L software, you’ll be able to swap out parts from Google’s Project Ara modular phone without turning the device off, notes the Phonebloks blog. Obviously, this doesn’t apply to the phone’s display or CPU modules. Everything else is fair game, though. That means if you want a better camera or more memory at some point during the day, you can simply replace those modules on the fly without having to shut down and restart your phone. I could see that being very handy for the camera sensor: Perhaps you’ll carry different imaging modules for various lighting conditions or types of photos. In fact, during the Linaro Connect USA event held earlier this month — Linaro is assisting with the software — Paul Eremenko, head of Project Ara for Google’s ATAP group, asked this very question: “Why choose a phone for its camera…when you could choose a camera for your phone?”
