Actually we have seen press image of single-sim version of the above device back in November. We don’t have an idea about existence of this device yet, but it looks like a new member of Asha 5XX family.
To me the display looks somewhere between 3.2 to 3.5 inch and the design of this device looks different from other Asha 5XX devices. The design of top bezel, home button and side profiles are all different form other Ashas. One more interesting thing is the presence of Bing search on both this and earlier leaked single-sim versions. So, will it come with more Microsoft influence?
We will let you know once we get to know something more about this device.
