What we have here might be our first glimpse at the Moto E. On the left is the low-cost Moto G, and on the right is a phone we haven't seen before, bearing Motorola branding and the markings of a unit used for testing before release. It has a smaller screen and body, though with what looks like might be thicker bezels. But for a phone that's said to be thinner and cheaper, that's a small compromise to make.
The photo, as posted by Android Police, is said to have been pulled from Motorola Mexico's Facebook page (¿alguien cometió un error, eh?). In addition to the slightly smaller screen, the device pictured here also has a larger speaker slot (and possibly one under the screen). It also appears that there is not a front-facing camera on this device, which is both odd and understandable if Motorola's looking to save customers even a few more dollars here. That pill-shaped black spot is likely the proximity and ambient lighting sensor, as on the Moto X and Moto G.
If this is the Moto E, we expect it to be what we'll see in next week in London. Specs wise it's anticipated to be similar to the Moto G, though down a notch in a few places in order to attain that lower price for markets where that sort of device is welcome — like Mexico.
