According to someone with knowledge of the device, the RM-1072 will feature a 5-inch screen with resolution of 720 x 1280. A quad-core Snapdragon 400 CPU will drive the phone and 8GB of native storage will be on board. Additional memory will be available through the phone's microSD slot. On the back of the handset will be an 8.7MP PureView camera while a .9MP snapper handles self-portraits. The unit will support dual SIM cards. The rest of the specs are supposed to match those of the Nokia Lumia 830, which means we should expect the phone to come with 1GB of RAM and a 2200mAh battery.
The RM-1072 is expected to cost $275, lock, stock and barrel. The model has already been certified in Indonesia along with the RM-1099 and the RM-1077, two other mystery Lumia phones that we hope to hear more about soon.
