This is the first product from Essential, the most recent company created by Andy Rubin, who was the co-creator of the Android smartphone platform and led that group at Google.
CNBC recently reviewed it. It's one of the best smartphones we've used in a while, though it has a few shortcomings.
One feature we didn't get to cover, however, is the new accessory dock. Essential is building all sorts of gadgets to attach to the phone. The first is a 360-degree camera.It attaches to the back of the phone. Surprisingly, the magnets seem to be really strong. It won't slip off in case you're taking a 360-degree photo over the Grand Canyon.
