Grab your calendar and turn in your vacation notice, Nokia fans, because the Finnish phone manufacturer looks like it's got something big planned for Oct. 22. Nokia just posted the image you see above to its official Twitter account along with the tagline "At Nokia, we never stop innovating. More to share on October 22 #Nokia #innovationreinvented."
Nokia hasn't shed much more light on what it's got planned for this Oct. 22 announcement, which I suppose is why they call these things teasers. If the rumor mill is to be believed, though, the Windows Phone maker will use the event to introduce us to the Lumia 1520. Expected to be the first Windows Phone in the phone/tablet hybrid category of devices, the 1520 will reportedly pack a 6-inch 1080p display, quad-core Snapdragon 800 processor, 20-megapixel camera and 3400mAh battery.
