The last two years have marked four major Sony flagships, putting them on a 6-month release schedule for each flagship phone. Given that the Xperia Z3 came out just a few months ago we figured there would be rumors of the Z4 coming out in early 2015, and this latest batch of rumors seems to help that theory along. The last time we saw rumors about the Xperia Z4 it was paired with an Xperia Z4 Ultra, something Sony hasn’t done in quite a few iterations of the phone now. The phone is still supported and actually just got an Android 5.0 Lollipop release for the Google Play editions of the phone, but given the age of the device it’s not surprising to see a follow-up possibly coming soon.
Focusing on the regular sized Xperia Z4 it looks like Sony will be sticking with the 5.2-inch screen that it’s been using for quite some time now, and the resolution is now rumored to be unchanged from the Xperia Z3 as well. That’s a 1080p Triluminos LCD display if you haven’t been following Sony’s displays. Given how significantly the quality has been upgraded on the screen of every single Xperia Z device even though the resolution hasn’t changed in a while, we expect this to see the same quality improvements that have been trending with Sony’s updated phones lately too. You’ll also notice significantly smaller bezels on the Xperia Z4, which fall in line with the last rumors, and show a significant departure from the bezels of older Sony phones even including the Xperia Z3. The Xperia Z4 is quite a bit smaller compared to the Z3 because of it!
Moving to the inside components of the Xperia Z4 these leaked slides from an internal Sony computer show that the phone looks to be receiving a chipset upgrade to at least the Snapdragon 805, which powers the Nexus 6 and Galaxy Note 4, although there’s a slight possibility that we could see the first big 64-bit chipset from Qualcomm inside too, the Snapdragon 810. This all depends on Sony’s R&D schedule and when Qualcomm has the Snapdragon 810 chipset available for widespread use too. Last but not least is the camera sensor which is apparently set to get an upgrade to the Sony Exmor IMX230 21-megapixel sensor, which is a generation ahead of the current 20.7-megapixel sensor in the Xperia Z3. All this points to a device that’s slated to feature some significant upgrades come the spring, so stay tuned to see what sticks and what doesn’t as the rumor mill continues!
