Update: we’ve asked the question at the end of the post, and it looks like it’s been answered. Apparently, the Xperia Z4 is only for Japan, but the rest of the world will get a different flagship by the end of May, according to this report.
Finally all the rumors can come to an end as Sony announces the Xperia Z4, one of the most rumored (and leaked) smartphones of the year. It will replace (or at least it will try) the predecessor, the Xperia Z3, which was already an incremental upgrade to the Xperia Z2. If you were expecting a design overhaul, you’ll probably be disappointed, as Sony has decided to go with the same design and build (glass and aluminum sandwich).
However, on the inside, the specs have been bumped to make the already fast Xperia Z3 even faster with the Z4. A Qualcomm Snapdragon 810 processor sits at its core, helped by 3GB of RAM and 32GB of internal storage (expandable via microSD card). The screen is (still) a 5.2-inch unit with Full HD resolution, and the camera on the back is still one of 20.7 megapixels, with a 1/2.3-inch Exmor RS sensor behind the lenses and Sony’s own BIONZ image processor. The camera on the front has been dramatically bumped to 5.1 megapixels, while the battery takes a slight hit, the Xperia Z4 packing a 2,930mAh battery.
Weighing 144gr. and measuring 6.9mm in thickness, the Xperia Z4 is slimmer and lighter than its predecessor, but it is just as dust and water resistant with its IPX5/IPX8 ratings.
There is no word and details about exact pricing at this point, but Japan should see the Xperia Z4 sometime this summer. Whether this will be a Japanese-only unit (judging by its current appearance only on the Japanese website) or it will go global is yet unknown.
