Microsoft Lumia 640 will be one of the first to receive Windows 10 update20
Besides discussing the update, Korpela calls the Lumia 640 an affordable high-end model. The device is equipped with a 5-inch screen carrying a 720 x 1280 resolution. This combination produces a pixel density of 294ppi. A quad-core 1.2GHz Snapdragon 400 CPU is under the hood with 1GB of RAM inside. The Lumia 640 comes with 8GB of native storage, and for those who need additional memory there is a 128GB microSD slot available. An 8MP camera adorns the back of the unit and there is a .9MP front-facing snapper ready to shoot selfies. A 2500mAh battery keeps the lights on.
Since the mobile version of Windows 10 is still months away, promoting the handsets that will be the first to receive the update is an important sales tactic for Microsoft. Most new phone buyers aren't going to twiddle their thumbs waiting for Windows 10 for Phone to be released.
