Sony just announced the Xperia Z and the Xperia ZL. The two phones are very similar from what we can tell so far. The Xperia ZL sports the same 1.5GHz quad-core Qualcomm Snapdragon processor as the Xperia Z, as well as a 1920 x 1080p 5-inch display, 2GB of RAM, 4G LTE support and a 13-megapixel camera.
Unlike the Xperia Z, however, the ZL doesn’t appear to be water resistent. The two looked nearly identical in our brief look at both of them, so we’re guessing there isn’t much of a difference on the surface. The Xperia ZL is due out during the first quarter of this year.
