The Sony Xperia Z1s should be announced early next year as the mini version of the Xperia Z1. It appears that the Xperia Z1s model number will be D5503 with codename Amami. This fits the naming scheme of this being the first 2014 Sony Xperia handset. When Sony moved to its new model numbering system, the first letter determined the year. So ‘C’ was 2013, ‘D’ is 2014, ‘E’ is 2015 and so on.
This particular model is the European LTE version and shows that the Xperia Z1s is likely to see a global release. It also highlights where this particular model will sit in its 2014 line-up. The 2013 equivalent was the Xperia ZR (C5503) which had a 4.6-inch 720p display. We spotted some sample images from the D5503 on Flickr and you can see the Exif information below. It shows that the handset was running firmware version 14.2.A.0.204. We’ll bring you more details as we have them.
