Based on the naming scheme we can only assume that these handsets are the successor to the Lumia 635. That being said, what can we expect from these two new handsets? The leaked specifications of the Lumia 640 claim that it will come with a 5-inch display, 1GB of RAM, and 8GB of onboard storage. It is also said to be powered by Qualcomm’s Snapdragon 400 processor which makes it a somewhat low-end device.
The specs are also stating that it will come with an 8MP rear-facing camera, and a 1MP front-facing camera. As for the Lumia 640 XL, it is unclear as to what the difference is at the moment, but we can only assume that it will sport a larger display, but as to whether it will be more powerful remains to be seen. In any case Microsoft will be making their announcement tomorrow so be sure to check back with us then for the official details.
