Now thanks to a recently leaked photo, we have an inkling of what it could look like. The photo has recently surfaced on Baidu and it basically shows us the back of the phone without its cover, essentially showing off some of its innards in the process. Of course this could be pretty much any phone so take it with a grain of salt for now.
The photo also has some text overlaid on it which more or less confirms what we know about the handset so far. The Lumia 1330, if the rumors are to be believed, will feature a 5.7-inch 720p HD display. This is actually a slight decrease from the Lumia 1320 which had a 6-inch 720p HD display, but with the smaller screen it would theoretically be sharper.
It will also be powered by a Qualcomm MSM8926 chipset with 1GB of RAM, a 14MP rear-facing camera with ZEISS optics and a 5MP front-facing camera, both of which are major upgrades over the Lumia 1320. Take it with a grain of salt for now but with CES and MWC 2015 around the corner, perhaps we will learn more about it officially soon.
