Apparently spotted somewhere in China, the new smartphone seems to be running Windows Phone 8.1 Update 1. As we told you yesterday, this update should bring various enhancements to WP, including the ability to organize apps into folders (called Live Folders).
The Lumia Tesla supposedly has a PureView camera on the back. Its display looks pretty large, so it might measure around 5 inches. We don’t know much else about the handset, but it’s said that this will be released by Microsoft as an “affordable high-end” device.
Microsoft may want to announce the Lumia Tesla at the same time with another new Windows Phone 8.1 handset that’s codenamed Lumia Superman (reportedly, this will feature a 4.7-inch display and a 5MP front-facing camera). While the Lumia Superman is expected to go on sale in the US as soon as next month via Verizon and AT&T, for the moment we don't have details on the availability of the Lumia Tesla. But we'll certainly keep an eye on this, and get back to you when new info arrives.
Update: Actually, this handset may be just a white Lumia 1520. However, it's definitely running Windows Phone 8.1 Update 1.
