Sony in a press event invite has teased its rumored 6.44-inch smartphone, currently known as Xperia ZU, Xperia Z Ultra and Togari.

According to the image, the company will host a special media event in Paris, France, on July 4, during which the Sony Xperia Z Ultra will most likely be unveiled.

The image shows the ultrathin profile of a rather long device, which has the same on/off button on the side just like the Xperia Z and other recent Sony smartphones. On the same side, we can see the headphone jack, towards the top, the volume keys and a dedicated camera button. Another hole is present towards the bottom side of the handset.

Furthermore, the company hints at something big in the invite itself: “Sony Mobile reserves a big surprise for you,” the text says. We also notice the stylus/pencil presumably used to add a note on the invite. The note reads: “Do not forget to mark your calendars!”

This isn’t the first media event whose star is said to be the Xperia Z Ultra. Sony has scheduled a similar event for June 25 in Munich, Germany, although that invite doesn’t actually show the device.

We have seen a variety of Xperia Z Ultra rumors recently, with some of them showing purported images of the unconfirmed device. But this is the first actual image of the unannounced smartphone.

When it comes to specs, the handset is said to pack a 6.44-inch 1080p “Triluminos with X-Reality for Mobile” display, 2.2GHz Qualcomm Snapdragon 800 chip, Adreno 330 graphics, 2GB of RA, 16GB of storage, microSD support, 8-megapixel camera, 2.2-megapixel front-facing camera and Android 4.2 Jelly Bean. The handset is rumored to measure 179.2 x 92 x 6.5mm and weigh 212g.

We’ll be back with more details about the Xperia Z Ultra once we have them.
