That leaves a space in the middle, but that could soon be filled following the leak of images purporting to be the Moto M. The alleged mid-range smartphone sports an all-metal body and a rear-mounted fingerprint scanner, features commonly reserved for more premium devices.
The rumoured specs for the Moto M are also pretty impressive: 2GHz quad-core Snapdragon 625 processor with either 3GB or 4GB RAM with 32GB of storage and 4GB RAM with 64GB of storage depending on the market. Both versions appear to have a microSD card slot that will let you expand storage by up to 128GB.
On the front there's expected to be a 5.5-inch full HD 1080p display, dual microphones and a mammoth 5100mAh battery.
The image and specs leak doesn't mention price or release date, but considering there's a fully-built version of the phone, we should hopefully start seeing more news soon.
