On XDA Developers forum, some of the images were leaked of an unknown device having 5.2-inch dispaly and running on Android 4.3 jelly bean. The handset was carrying the model number “D6503”, although no official handset has been identified.
The image shows that handset with three speaker holes, a microUSB port on the left side, a SIM tray and a microSD slot on the right. Somewhat similar to Sony’s Xperia Z1 include the power button, volume rocker, camera button, headphone jack, magnetic pens, and notification light.
Some more identification like, G-lens logo on the back expect it to match Sony Xperia Z1’s 20.7MP. May this will soon unveil in the upcoming Mobile World Congress.
