Apart from the Z Ultra, Crossmap states that Sony’s Xperia Z1 (formerly Honami) has also generated a lot of interest. The device has a TFT screen of 5.0in with 1080 by 1980 pixels.

NDTV stated that it will have the same TRILUMINOS display found on the Z Ultra and will operate on Android OS Jelly Bean 4.2.2. The 2.2GHz it runs on will come from a Snapdragon 800 MSM8974 processor.

Crossmap also states that the Z1 will be available with a Sony G lens and BIONZ. The camera will be of 20 megapixels. It will go on sale across the globe in September as well.
