Back in November AdDuplex noticed a 5 inch 720P screened Windows Phone handset, the RM-1072, using their advertising network.
Now NokiaPowerUser has discovered the handset passing through certification in Indonesia.
With a 5 inch 720P screen the device is clearly more mid-range rather than high end, and it may be one of the new generation of 5 inch LTE Snapdragon 410 13 megapixel Windows Phone reference designs we recently saw Yezz announce.
While our readers may be reluctant to trust Yezz, I suspect many will be a lot more excited about such a device coming from Microsoft.
We should hopefully learn more about the device by Mobile World Congress in March 2015.
