A day ahead of the official announcement at Mobile World Congress 2015, Microsoft ha accidentally posted an article with a few details about Lumia 640 and Lumia 640 XL. The article was pulled back very fast, but NPU knew what the company had in its sleeves.
As MWC 2015 has officially started today, Microsoft decided to unveil both smartphones. The Lumia 640 features a 5-inch IPS 720p display that has Gorilla Glass 3 protection. It is powered by a quad-core Snapdragon 400 clocked at 1.2 GHz and paired with 1GB of RAM.
