As for the software version of the Sony Xperia Z1s, it has been listed as 14.2.A.0.144, which should point to Android 4.3 Jelly Bean (apparently, when it came to the Xperia Z Ultra, 14.2.A.0.290 happened to be the listing which was equivalent of the Android 4.3 Jelly Bean update). For those who are not in the know, the Sony Xperia Z1s happens to be a smaller version of the Z1 flagship, where it comes equipped with a 4.3″ 720p display, running on a Snapdragon 800 chipset, sporting a 20.7-megapixel camera alongside a water-resistant design. Whispers on the street have it that the Sony Xperia Z1s will arrive sometime in the first quarter of next year, sporting a $590 price point. [FCC Page]
