New WP leaker Xero has posted some parts of render of mysterious Lumia device, revealing some more information on upcoming WP update and future Lumia devices.
The first screenshot shows what appears to be a lockscreen with a percentage based battery meter. It also reveals that Microsoft is going to use the “LUMIA” branding instead of “Nokia” on future phones. Also the 18:20 timing on leaked screenshot suggests a new WP device Lumia 1820.
The second screenshot is also of lockscreen (lower part), showing user action on some unread notification.
