One of the more interesting smartphone-related projects that Google is currently prepping is, undoubtedly, the Android-powered ARA modular smartphone, which will allow you to snap different hot-swappable modules on an endoskeleton (simply addressed as "endo" by its creators) and thoroughly change the hardware setup of your device. Well, a beta release of the compelling gadgetry might see the light of day in just a few months' time, sometime in March 2015.
Google has already filed in a trademark for the "ARA" name with the United States Patent and Trademark Office, hinting us that the modular device most probably won't see its name changed right before the first modular devices and modules officially break cover. Then again, Mountain View might strap another fancy name to its curious project, but the "ARA" moniker will probably stick for the time being.
We already know that the modular device will run a custom version of Android 5.0 Lollipop and most of its modules (except for the CPU and display units) will be hot-swappable. Google has already released a developer's board for the ARA phone. All in all, the ARA handset has already become a substantial part of the Android folklore and we can't wait to learn more about the captivating project.
