A new image emerged in Google’s pic sharing platform Picasa, shot with an unseen yet new Xperia device. It has a model number C503 and the codename HuaShan. It seems we are talking of a middle-range device with specs yet unknown, however its camera is of a 5-megapixel variety which seems a little disappointing for a 2013 device. What’s interesting is that HuaShan runs Sony’s eDream firmware ver. 12, while most Xperia devices are running ver. 10. More details will follow when available.
