As the latest round of rumors stated, the Motorola One Action does not run on Android One, despite being part of the "One" lineup. That is for the US, at least. Outside of the US, it will still run on Android One.
Motorola is actually going to be phasing out Android One, seeing as it has found that it is not the most important thing to its customers. Some might be worried that this means that updates aren't coming to the Motorola One Action. Well, they are coming. But, Motorola is only promising a year of software updates. That is at least longer than the Moto Z4 is getting.
The Motorola One Action sports a 6.3-inch Full HD+ CinemaVision display, that's with a 21:9 aspect ratio. Meaning that Motorola is the second smartphone maker to jump to 21:9, following Sony earlier this year. For a phone that has an action camera, this is actually a good thing. As you can shoot in cinema mode.
Internally, you'll find the Exynos 9609 chipset, and that is paired with 4GB of RAM and 128GB of storage. There is also a micro SD card slot available if you need some more space. All of this is powered by a somewhat large 3500mAh capacity battery, and there is also a 10W fast charger included in the box. So you can top off the One Action anytime.
Now it's time to get to the meat and potatoes of the One Action, and that would be the camera. It has a 16-megapixel main camera on the back, with a 117-degree field-of-view. It pulls double duty, by using pixel binning technology to output 4-megapixel photos with a 2um pixel size for some better low-light photography. That camera is really only meant for video though, but it can still take photos as you might expect. It does support shooting in 21:9, 18:9 and 16:9 aspect ratios.
There are three cameras on the back. The secondary sensor is a 12-megapixel sensor at 1.25um pixel size. It also has a f/1.8 aperture. This is the sensor that you would be using for photos, most of the time. Then there is a 5-megapixel depth sensor, to add some bokeh to your photos. Cinemagraph and Spot color are also coming to the One Action.
The Motorola One Action will be coming to the US, but so far we only have pricing on the European model. It's slated to be priced at €259 over in Europe. That translates to around $285 in the US. So it's likely it'll be under $300 when it does launch here. For a smartphone that also doubles as an action camera, that's not a bad price at all. Seeing as you can spend a lot more on a GoPro, and get no WiFi connectivity. Remember that the One Action also gets Google Photos support, so you have plenty of space to store all of those photos and videos.
