A member at XDA has some photos and rumored specs of some Sony smartphone. The device has a model number D6503, a 5.2” display, thinner bezels and has a new UI with Android 4.3 Jelly Bean. Seeing the model number, what can be speculated is that this may be a successor to the Xperia ZL. However, the camera on the back shows it to be 20.7MP which is same as that in Xperia Z1 and the Xperia Z1 Compact. Here are the leaked images of the device.
What other things the images reveal is that three large speaker-like grills at the bottom, the micro USB slot and SIM tray at the left side, the lanyard eyelet on the left side and a microSD slot on the right side.
Other connections include the camera shutter button, power button, magnetic pin connectors, LED notification light and headphone jack.
