Microsoft isn’t giving up on its Android smartphones. After acquiring Nokia’s phone business in April, Microsoft is introducing a new Nokia X2 handset today. Although the specifications aren’t wildly different to the previous model, 1GB of RAM should help boost the performance of app switching, a feature that felt a little slow during our initial look at the original Nokia X. The Nokia X2 also includes a home button alongside the regular back button. The most surprising part of the Nokia X2 for many will be that Microsoft is continuing to invest in these Android-based handsets. Nokia’s original X device blended Windows Phone-like UI with Android and Microsoft services, and the X2 does exactly the same with slightly refreshed and refined hardware.
